摘要：

The charophytes Chara corallina Kl. ex Willd. and Nitella sustilissima A. Br. are present in temporary wetlands in Australia. The mean maximum percentage germination of these two species and the number of oospores in the seed bank are compared using germination and total count methods of seed bank analysis. The pattern of germination in both field and laboratory studies and the fate of individual sporelings of both species is examined. C. corallina showed a pattern of later germination of 5% of the seed bank, a high rate of establishment and early reproduction, whereas N. subtilissima had earlier 13% germination, poor establishment and did not reproduce during the experimental period. The life history patterns of these species are compared. © 1990.
