中文摘要 | 在春、秋兩個期作下,KS2 與 68-I-J 兩個紅豆品種的形態發育有很大的差異。 68-I-J 在春、秋兩個期作均為無限生長丑,總乾物質生產在兩個期作間沒有明顯差異, 但 是種子產量以秋作較高。KS2 在秋作為有限生長型,在春作為無限生長型,總乾物質生產以 春作較高,約為秋作的 2 倍,但是春作的種子產量僅為秋作的 70%。 兩個品種在春作產量 降低的主要成分是種子百粒重減少,約減少 40 ∼ 46%,亦即是種子充實不良。 春作的總乾物質重、LAI、LAD、NAR、CGR 等供源成分並不比秋作低。 由此可知,春作的產 量減低與種子充車不良,並非由於供源不足,而是由於積儲成分較差與分配效率降低所致。 |
英文摘要 | The morphological developments of two varieties of adzuki bean(KS2 and 68-I-J)were significantly different between two crop seasons. 68-I-J showed the indeterminate growth habit both in spring crop and in fall crop. However, no si gnificant difference in total dry matter production was detected between two cro p seasons.But, the seed yield was significantly greater in the fall than that in the spring. KS2 showed the determinate growth habit in fall crop season, but ex hibited indeterminate growth in spring. The rpoduction of total dry matter in spring was two fold higher than in the fall. And, in spring it only produce 70% seed yield of the fall crop. The decrease in seed yield for both varieties were mainly due to a poorer seed-filling.And, 100-seed weight showed 40 to 46% difference between two crop seasons. The components of source for both varieties such as LAI, LAD, NAR, CGR were not worse in spring than in fall. Consequently, the seed yield and seed-filling reduction came from the reduce sink accumulation and lower partition efficiency. |
