Bamboo plants are particularly exposed to this abiotic stressor in southern China, which makes it essential for researchers to conduct relevant studies to fully understand the pernicious effects of HMs on various biological and physiological aspects of bamboo. V-51 ABIDJAN (Côte d'Ivoire) (2) ENSA, 08 BP 35 Abidjan 08 (Côte d'Ivoire) (3) B.P. Afshan et al. If you continue browsing the site, you agree to the use of cookies on this website. Morphological indices were also depressed as a result of the adverse influence of HMs, leading to decreased shoot length (10 to 73%) and reduced number of emerged plants (6 to 57%). This necessitates the investigation of the effects of HMs on growth and physiological properties of bamboo. Physiological characteristics like transpiration and photosynthesis rate, chlorophyll index, leaf water potential, and relative water content also could be appropriate indices for monitoring plant water status and computation the real value of LLWR and IWC … Rubén Díaz‐Sierra, Mart Verwijmeren, Max Rietkerk, Víctor Resco Dios, Mara Baudena, A new family of standardized and symmetric indices for measuring the intensity and importance of plant neighbour effects, Methods in Ecology and Evolution, 10.1111/2041-210X.12706, 8, 5, (580-591), (2017). The southern regions of China are severely impacted by human-induced heavy metal (HM) contamination, which poses an impediment to growth and productivity of bamboo (Indocalamus latifolius) plants. PY - 2012/3/1. Review articles are excluded from this waiver policy. Leaf growth, plant weight etc. Investigating factors involved in the alleviation of the toxic effects of heavy metals (HMs) on plants is regarded as one of the important research concerns in the environmental field. Growth Responses and Photosynthetic Indices of Bamboo Plant (Indocalamus latifolius) under Heavy Metal Stress. EFFECTS OF PLANT DENSITYAND SOIL MOISTURE ON GROWTH INDICES OF TWO UPLAND RICE VARIETIES N'guettia R. YA0 (11, Bernard COUÉ (11, Koffi. Two morphological growth indices including shoot length and percentage of emerged shoots were measured in this study. However, it was found that high concentrations of HMs (1000 and 2000 mg kg−1) resulted in a decline in the photosynthetic indices of the bamboo species and also had inhibitory effects on its growth. A staple of much of the world’s table, the cassava plant (Manihot esculenta) can be grown in the home garden as well. The excessive levels of heavy metals (HMs) in the soil, which mainly stem from human-induced activities, are a major threat to human health, plant productivity, and wildlife [1, 2]. AU - Norton, Randall. To investigate the effects of superabsorbent polymers on water requirements and growth indices of Ficus benjamina L. ‘Starlight’, rooted cuttings were planted in media and treated with six levels of superab-A 200 polymer (0, 0.2, 0.4, 0.6, 0.8 and 1.0%) and four irrigation intervals (4, 8, 12, and 16 days). Moreover, the assumption should be tested in bamboo plants whether or not HMs in low concentrations are beneficial to their growth and development. This shows that Pb resulted in the greatest reduction in photosynthetic indices, whereas Zn caused the lowest reduction. viii. Growth Responses and Photosynthetic Indices of Bamboo Plant ( Indocalamus latifolius ) under Heavy Metal Stress AbolghassemEmamverdian , 1,2 YulongDing , 1,3 FarzadMokhberdoran , 4 HMs are increasingly becoming major environmental contaminants that affect all living organisms. MDWI [R max(1500–1750) –R min(1500–1750)]/[R max(1500–1750) +R min(1500–1750)] was a newly proposed water index that incorporated short-wave infrared wavelengths and was more efficient at detecting changes in plant water status compared with the indices that employ near infrared wavelengths (NDWI and WI) (Eitel et al., 2006).

Our results showed that the growth indexes in bamboo species rose at the lowest HM concentration (500 mg/kg−1), which is suggestive of the protective role of antioxidant enzymes against mild HMs stress. Now customize the name of a clipboard to store your clips. description about Growth and developmental analysis indices in crop production. Looks like you’ve clipped this slide to already. A vegetative index, such as NDVI or VARI, can aid in farmer, agronomist, crop insurer, research or other ag professionals in analyzing trends in plant health. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Our results indicated that the lowest concentration of HMs (500 mg kg−1) positively contributed to the growth of bamboo species, but there was a significant reduction in the plant growth indices (shoot height and the number of emerged shoots), when HMs levels were further increased to 1000 and 2000 mg kg−1. The effect of plant growth promoting rhizobacteria (PGPR), salicylic acid and drought stress on growth indices, the chlorophyll and essential oil of Hyssop (Hyssopus officinalis). Abstract. Vertical bars in the figures indicate standard deviation (SD). These observations are in line with the findings of Chen et al. This leads to reduced energy transmission to the photosynthetic reaction centre [19]. This work was supported by the Special Fund for Forest Scientific Research in the Public Welfare from State Forestry Administration of China [no. Our findings suggested that almost all photosynthetic properties decreased with an excess of HMs (except Cu and Zn in 500 mg/kg−1). Similar observations are reported for sunflower and corn where net photosynthesis and transpiration were declined by HMs stress [23]. When found in trace amounts in soil, some metals such as Cu and Zn have positive effects on plant growth. Moreover, we found that the number of the emerged bamboo stands in the species used in our study was reduced when it was subjected to excessive amounts of HMs. According to the results, the percentage of the emerged plants was about 1.06-fold higher than the control at Zn 500 mg kg−1, but it was about 1.31-, 1.35-, and 1.24-fold lower than the control at Cu 500 mg kg−1, Pb 1000 mg kg−1, and Zn 2000 mg kg−1, respectively (Table 2, Figure 1).  GROWTH ANALYSING PARAMETERS In growth analysis, crop growth is expressed as a function of time, but as can be seen from the three components of rate dry matter accumulation, crop growth should be expressed in terms of absorbed solar radiation. The growth parameters were increased by 4% and decreased by 40% under the 1000 and 2000 mg/kg−1 Pb treatments, respectively. Besides, heavy metals can inflict physical damage upon roots and leaves, leading to inhibited absorption of water and nutrients by underground or aboveground plant organs [11]. of Arizona, 37860 W. Smith‐Enke Rd., Maricopa, AZ, 85138 The objective of the study was to investigate some gas exchange parameters and growth indices in two-year-old bamboo species (Indocalamus latifolius) under heavy metal stress. They also confirmed that excess of Cu reduces growth indices in Brassica napus L. [27]. 2018, Article ID 1219364, 6 pages, 2018. https://doi.org/10.1155/2018/1219364, 1Co-Innovation Center for Sustainable Forestry in Southern China, Nanjing Forestry University, Nanjing 210037, China, 2College of Biology and the Environment, Nanjing Forestry University, Nanjing 210037, China, 3Bamboo Research Institute, Nanjing Forestry University, Nanjing 210037, China, 4Department of Agronomy and Plant Breeding, Faculty of Agriculture, Islamic Azad University, Mashhad Branch, Mashhad 94531, Iran.

Emamverdian A(1)(2), Ding Y(1)(3), Mokhberdoran F(4), Xie Y(1)(2). HMs are viewed as one of the chief culprits for the contaminated human and animal food chains. Growth and yield are functions of a large number of ... different growth indices (Roderick, 1990; Sepetolu and Budak, 1994): LAI = L / P, RGR = 1 / W * dw / dt, NAR = 1 / L*dw / dt, Soil Biota and Organic Residue Decomposition Methods, Customer Code: Creating a Company Customers Love, Be A Great Product Leader (Amplify, Oct 2019), Trillion Dollar Coach Book (Bill Campbell). You can change your ad preferences anytime. The results illustrated that excessive HMs (1000 and 2000 mg kg−1) triggered a decline in a number of photosynthetic-related indices including the rate of photosynthesis (μmol CO2 m−2 s−1), intercellular CO2 concentration (μmol CO2 mol−1), conductance to H2O (mol H2O m−2 s−1), and net assimilation as well as transpiration. OMF on some growth indices of tomato plant were examined. In order study of physiological growth indices in maize (Zea mays L.) hybrids under different plant densities application, a factorial experiment based on randomized complete block design was conducted at Research Farm of University of Mohaghegh Ardabili in 2007. The extreme concentration of metals in the soil can bring about detrimental changes to plant photosynthesis, eventually leading to the reduction of plant growth and yield [7]. These observations are in agreement with the results of our experiment, where it was revealed that HMs stress in high concentrations negatively affected the percentage of shoot length, resulting in decreased shoot length. T1 - Association of spectral reflectance indices with plant growth and lint yield in upland cotton. Investigation of the Effect of Plant Growth Promoting Rhizobacteria on Some Growth Indices and Yield Parameters of Safflower Under Different Soil Salinity Levels . AU - Thorp, Kelly R.

It is measured as the mass increase per aboveground biomass per day, for example as g g−1 d−1 . Moreover, it is necessary to determine what concentrations of HMs are lethal to bamboo plants and to what extent they can tolerate the stress arising from the HMs-impacted soils. It was revealed that vinasse fertilizer formulated with 9% of N PK exhibited the best impact to the tomato plant growth. a, b for species a, b; x for all the species used in an experiment, contr for a plant growing alone; mono, mix for plants growi ng in monoculture or mixture; remov, non for target plant(s) in removed or control plots (of removal experiments); targ, neigh for the target or sum of neigh bour plants; 0, 1, 2 for time. Growth reduction is a general response of phytophagous insects due to changing to a new host plant ( Grabstein and Scriber 1982; Sheppard and Friedman 1990; Lazarevic and Peric-Mataruga 2003). Bamboo plants cover large parts of China forests [12, 13]. Another aim pursued in the study was to find out if HMs in low concentrations contributed positively to the growth parameters of the bamboo plant. Photosynthetic-related parameters including net photosynthetic rate (PN), conductance to H2O (Cond), intercellular CO2 concentration (Ci), and transpiration rate (Tr) were quantified using the LI-6400XT Portable Photosynthesis System (LI-COR, Lincoln, Nebraska, USA). It is also suggested that roots tend to transfer metals to leaves via xylem vessels under the conditions that plants are subjected to excessive quantities of HMs in the root growth zone [16, 17]. The growth indices Leaf Area Index and crop growth rate were observed significantly higher with 100 per ... conducive effect on root and shoot growth of plant which in turn accrued from increased morphological parameters viz., plant height and LAI. Author(s) : Sharifi, P. Absorptance of incident solar radiation (IA')  INTRODUCTION TO GROWTH  DETAIL DISCUSSION ABOUT GROWTH ANALYSING PARAMETERS Therefore, it is important to provide some quantified information about the impacts of heavy metals on a number of growth and physiological aspects of this plant. GROWTH ANALYSIS Growth analysis is a mathematical expression of environmental effects on growth and development of crop plants.

This is a useful tool in studying the complex interactions between the plant growth and the environment. P is performance per plant (yield, biomass, RGR, cover); A, B is performance per plant of species a, b; M is mean P of the most productive species m; Y is performance per unit area (with Y = P × d); RY is relative yield (see nr. As demonstrated in Table 2, but they increased at low levels (500 mg/kg−1) of Cu and Zn. The application of Cu led to an 11% increase at 500 mg/kg−1 and a 33% decline in growth parameters at 1000 and 2000 mg/kg−1. J. KOUADIO (2) et Guy / HAINNAUX (3) (1) ORSTOM-Adiopodoumé, B.P. The data used to support the findings of this study are available from the corresponding author upon request. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. 1999a; Jolliffe 2000; Sackville Hamilton 2001). Plant growth analysis is considered to be a standard approach to study of plant growth and productivity (Wilson, 1981). Zinc caused a 12% increase at 1000 mg/kg−1 and a 23% increase at 2000 mg/kg−1 in growth relative to the control (Figure 1). Plant nutrition is the study of the chemical elements and compounds necessary for plant growth, plant metabolism and their external supply. They can accumulate in plant organs and act as a growth inhibitor by disrupting plant vital physiological and developmental processes [3, 4]. circumstances of growth. Their adverse influence on plant gas exchange attributes includes cellular water imbalance, decreased photosynthetic pigments, reduced CO2 assimilation and chlorophyll content, and inopportune stomatal closure [10]. It gives Absolute values of biomass between two intervals. (2000) reported that the differences in growth indices of crops are normally attributed to their genetic constitution. ficantly increased physiological growth indices in maize which indicates that the highest TDW (1910 g.m -2 ), LAI (4.2), RGR (0.08 g.g.day -1 ) and CGR (31.2 g.g.m -2 .day -1 ) Generally, a significant drop in growth indices such as shoot and root length or plant height is reported in various plant species including Trigonella foenum-graecum L. grown under Cd stress , Jatropha curcas subjected to Pb excess , Glycyrrhiza uralensis seedlings exposed to Cd stress , tomato, canola, and Indian mustard seeds treated with Pb, Zn, and Ni excess , Vicia faba L. under Cd stress , and … Bamboo species under HMs stress on photosynthetic performance [ 20, 21 ] KOUADIO ( 2 ) et Guy HAINNAUX.
