【 摘 要 】

The influence of the shell on the moisture of groundnut seed was examined using two cultivars, Nakateyutaka, which had a large seed with a thick shell and Chico, which had a very small seed with a thin shell. In group 1, freshly harvested seeds were shelled or unshelled and forced air-dried at 28°C for 9 days. In group 2, the shelled and unshelled seeds after dry storage (dried seeds) were sown in vermiculite at a 3-cm depth at 28°C and grown for 5 or 6 days. In group 3, the dried seeds were placed in a room kept at 25-28°C with a relative humidity of 89-99% for about 13 weeks, and in group 4, the dried seeds were placed in a room at 26-28% humidity for about 13 weeks. The effect of shell on the seed moisture differed with the cultivar in groups 1 and 2, but not in groups 3 and 4. The seeds in groups 2 and 3 showed an about 12-hour imbibition period, but the shelled seed germinated earlier and at a higher moisture content than the unshelled seed in group 2. The seed in group 3 did not germinate due to very slow moistening. These results suggest that the function of the shell is not only to protect the seed but also to regulate the moisture of seed.
