Abstract:
The stem of kidney bean plant (Phaseolus vulgaris L., cv. Kentucky 101), a typical dextrorse climbing plant, was subjected to compulsorily sinistrorse-winding. The compulsory sinistrorse-winding induced changes in physiological activities. The number of pods with immature seeds (used as vegetable) was doubled and the fresh weight of the pods also significantly increased by sinistrorse-winding. Compulsory sinistrorse-winding increased chlorophyll content, photosynthetic rate, respiration, nodule formation, N(2)-fixation, glutamine synthetase [L-glutamate: ammonia ligase (ADP-forming); E.C. 6.3.1.2] activity and protein content. Thus, it seems to affect the basic physiological processes that promote physiological activities though the action mechanism is unknown.
