Dry matter production and partitioning in two cultivars of Phaseolus vulgaris under different watering regimes. (179)
Two cultivars of the common bean (Phaseolus vulgaris L.) were subjected to three watering treatments. Dry weights of leaf, stem, root, pod wall and seed, and leaf areas were recorded a_t 10-day intervals from emergence. There was a preferential distribution of dry matter to the roots as water!ng was decreas??d, both before and after flowering. Root weight and leaf area decreased after flowermg. A maJor source of assimilates to the developing seed appeared to be those re-translocated from the _leaves, root, stem and pod wall. The cultivars were not significantly different in their response to the watermg treatments.
