Abstract

Compared with short day treatment (SD 10h light a day), long day treatment (LD 15 h light a day) resulted in lower PS Ⅱ photochemical activity and lower efficiency of primary conversion of light energy in PS Ⅱ. The rate of electron transport in PS Ⅱ PS Ⅱ and through the whole chain under LD was lower too. The chloroplasts from LD-treated leaves of Nongken 58s (58s-LD) contained less chlorophyll b than 58s-SD. The marked decline of photochemical activity of Nongken 58s chloroplasts induced by LD may result in lower amount of various photosynthetic products, which are probably involved in the primary cause of male sterility.
