بررسی اثر سایه اندازی بر وضعیت کلروفیل در مراحل مختلف رشد نخود

In order to study the effect of shading on chlorophyll content at different growth stages of chickpea (ILC482) carried out a experiment via factorial in based on randomized complete block design with 3 replications in research farm on Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran during 2012-2013. Factors were including shading (no-shading, 25, 50, 75 and 100 percent) at different growth stages (vegetative and reproductive stages and all of growth duration). Results showed that shading intensity and shading stages and interactions between of them were significant on chlorophyll b and total chlorophyll at before anthesis and significant on chlorophyll a and chlorophyll b and total chlorophyll at grain filling period. The most of chlorophyll b and total chlorophyll were before flowering and at time of grain filling at shading of reproductive stage. The most and the lowest of Chlorophyll b and total chlorophyll obtained before flowering and at time of grain filling at no-shading and shading 100%, respectively.
