in order to study the effect of foliar zinc spraying on photosynthetic pigments and yield of chickpea under water stress conditions, a factorial experiment carried out based on randomized completely block design (rcbd) with three replications in university of mohaghegh ardabili agricultural research station in 2012. the treatments consisted of three levels of irrigation (irrigated at planting, ...

Jalapeño peppers at intermediate ripening stages (IRS) are typically discarded at the packinghouse because they are not demanded for fresh consumption or industrial processing. These peppers have been scarcely studied in terms of pigment composition and bioactivity. In this study, the profile of pigments (carotenoids and chlorophylls) and antioxidant activity were determined in raw and heat-pro...

I review the hypotheses that have been proposed to explain the adaptive value of autumn leaf colours. The available adaptive hypotheses can be reduced to the following. Photoprotection: pigments protect against photoinhibition or photooxidation allowing a more efficient recovery of nutrients. Drought resistance: pigments decrease osmotic potential allowing leaves to tolerate water stress. Leaf ...

Chloroplast pigments from young and old leaves of three chlorophyll-deficient peanut mutants (lutescens, auredus, and virescent) and two "normal" peanut genotypes ('Chico' and 'Guanajuato') were analyzed using high performance liquid chromatography. All genotypes showed chlorophylls a and b, carotene, lutein, neoxanthin, and violaxanthin in young and old leaves. Generally, there were decreases ...

A protocol has been developed for reconstituting visual pigments in intact retinae by delivering synthetic isomers of retinal incorporated in phospholipid vesicles. Calibration curves have been constructed relating the lambda(max) of the native porphyropsins (visual pigments based on 11-cis 3-dehydroretinal) of the rods and four spectral classes of cone in the goldfish, and the equivalent photo...
