Studies of Native Fodder Grasses in Japan : IV. Hard seed content of some wild legumes under storage conditions

[摘要] The hard seed content of Karasuno-endo (Vicia angustifolia L.) and Kawaraketsumei (Cassia mimosoides L.) which are being improved as fodder was investigated. Both immature and mature seeds of Karasuno-endo which had been stored for 1 or 3 months in the laboratory increased their hard seed content 0 to 62.7 % and 50 to 94.6 %, respectively. When immature seeds of Karasuno-endo were stored in a desiccator with water in the bottom of it, they retained their permeability entirely, but when stored with desiccant their hard seed content increased 0 to 99.3 % after 10 days of storage. Under storage condition in the laboratory mature seeds of Karasuno-endo reduced their percentages of hard seed in summer but didn't change them in other seasons. When they were stored with desiccant they showed high percentages of hard seed in every season. Mature seeds of Kawaraketsumei stored in the laboratory increased their hard seed content in winter and reduced in summer. Under dry storage condition with desiccant they reduced the hard seed content rapidly.
