Optimal Leaf Positions for SPAD Meter Measurement in Rice
The Soil Plant Analysis Development (SPAD) chlorophyll meter is one of the most commonly used diagnostic tools to measure crop nitrogen status. However, the measurement method of the meter could significantly affect the accuracy of the final estimation. Thus, this research was undertaken to develop a new methodology to optimize SPAD meter measurements in rice (Oryza sativa L.). A flatbed color ...
متن کاملAssociation of root, specific leaf area and SPAD chlorophyll meter reading to water use efficiency of peanut under different available soil water
Drought is the major abiotic constraint affecting peanut productivity and quality worldwide. There is a pressing need to improve the water use efficiency (WUE) of rain-fed peanut production. Breeding varieties with higher water use efficiency is seen as providing part of the solution. The objectives of this work were to (i) evaluate genetic variation in WUE, harvest index, root dry weight, spec...
متن کاملdetermination of best method of partitioning n fertilizer by using leaf color chart (lcc) and chlorophyll meter (spad) in rice
in order to determination of partitioning n fertilizer by using of leaf color chart (lcc) and chlorophyll meter (spad) in rice an experiment was conducted as split plot under randomized complete block design with three replications during 2006 and 2007 at rice research institute of iran. main plots were contained cultivars in three levels (grh1, khazar and hashemi) and sub plots were contained ...
متن کاملResponse of Chlorophyll, Carotenoid and SPAD-502 Measurement to Salinity and Nutrient Stress in Wheat (Triticum aestivum L.)
Abiotic stress can alter key physiological constituents and functions in green plants. Improving the capacity to monitor this response in a non-destructive manner is of considerable interest, as it would offer a direct means of initiating timely corrective action. Given the vital role that plant pigments play in the photosynthetic process and general plant physiological condition, their accurat...
متن کاملFLU: a negative regulator of chlorophyll biosynthesis in Arabidopsis thaliana.
Tetrapyrroles such as chlorophylls and bacteriochlorophylls play a fundamental role in the energy absorption and transduction activities of photosynthetic organisms. Because of these molecules, however, photosynthetic organisms are also prone to photooxidative damage. They had to evolve highly efficient strategies to control tetrapyrrole biosynthesis and to prevent the accumulation of free inte...
