Optimal harvest time for Medicago ruthenica seed

摘要：

Medicago ruthenica is an excellent perennial legume and widely distributed.The biggest problem limiting its development and application is seed production due to excessive seed shedding.It is a pivotal factor limiting seeds quantity and quality.So it is essential to determine the optimal harvest time to balance the seed loss and seed gain with high seed quality.Accumulation of degree‐days has been used to determine optimum harvest time ( Edwards, 1980).The objective of this study was to determine the optimal harvest time of M.ruthenica seed in northern China.
