Abstract
In this work, some photosynthetic pigments with acetone, methanol and diethyl either were extracted spectrophotometrically, in addition to SPAD chlorophyll meter frombean (Phaseolus vulgaris L.) var. Biotack and cowpea (VignasinensisSavi) var. California black eye leaves in vegetative, flowering and podding growth stagesin Koya city, Erbil- Iraq.Results shows that concentration of chlorophyll a in bean and cowpea leaves increased significantly when acetone used in the extraction process followed by methanol and the lowest obtained when the diethyl either is used, whereas methanol was the best solvent for extracting chlorophyll b.Results also show that there were nonsignificant differences in SPAD readings between different growth stages in both of bean and cowpea plants. The data shows that the SPAD reading is high in cowpea compare to bean plants.SPAD readings correlated high significantly with chlorophylls a and b concentrations, when acetone used as solvent in cowpea plants.
