✦ Synopsis

Accumulation of Ca, Mg and K, the principal cations in dry bean (Phaseolus vulgaris L) seed, was studied under Ðeld and greenhouse conditions. "Cran-09Ï, a cranberry bean and "NorstarÏ, a navy bean, were grown to maturity under greenhouse conditions. "Cran-09Ï had a seed weight of 605 mg, a seed Ca concentration of 1É2 g kg~1 and a Ca harvest index of 0É032. The corresponding three parameters in "NorstarÏ were a seed weight of 161 mg, a seed Ca concentration of 2É2 g kg~1 and a Ca harvest index of 0É064. The di †erence in seed Ca concentration was not due to increased absorption of Ca by "NorstarÏ, but rather was due to a larger proportion of Ca in plant tops being diverted to the seed component. The larger seed Ca concentration in "NorstarÏ was compensated to some extent by a smaller seed K concentration. In contrast to Ca, cultivar had relatively little e †ect on harvest indices for Mg, K, N and P. The average seed Ca concentration in six navy bean cultivars grown under Ðeld conditions was 90% more than that of three kidney and three cranberry bean cultivars.
