Chlorophyll content of the plant influences photosynthetic rate. Water stress caused a fall in leaf chlorophyll [3]. Increasing intensity of water stress decreased leaf chlorophyll content and tended to increase the chlorophyll a/b ratio [196]. Makhmudov [1983] reported that moisture stress inhibited biosynthesis of the precursor of chlorophyll in wheat leaves which ultimately reduced the chlorophyll content. Thimman [1980] stated that water stress induced leaf senescence leading to decreased photosynthetic activity with the accompanying degradation of proteins and chlorophyll. [47] Found increased level of carotenoid content under drought conditions. The chlorophyll content of the leaf was decreased by water deficit but there was accumulation of large amount of proline in the leaf. [13] stated that total chlorophyll content of the leaf declined under water stress conditions. It may be due to decreased synthesis and increased degradation of chlorophyll in leaves under water stress [57].
