中文摘要 | 本研究目的在探討不同落葉型品種間各生育期落葉性之變異,以供雜交親本的選定及育種選拔上的參考。試驗結果顯示春作三種落葉型各生育期之落葉性均不會影響到單株莢重的累積,但單株莢果產量則以延遲落葉型較高,其次為提早落葉型,最低為正常落葉型,其原因是延遲落葉型之莢果充實速率較提早落葉型及正常落葉型為高。在品種方面,僅有提早落葉型之中國赤ささげ及曉大納言兩品種之生育期落葉性會影響單株莢重的累積,其原因是此二個品種受生育期落葉影響,其莢果充實速率較低及有效充實期較短的關係。秋作除了延遲落葉型外,正常落葉型及提早落葉型之生育期落葉性均會影響單株莢重的累積,而單株莢果產量以延遲落葉型較高,其次為正常落葉型,最低為提早落葉型,其原因是延遲落葉型之莢果充實速率較高及有效充實期較長的關係。在品種方面,有正常落葉型之早生大粒品種及提早落葉型之圓葉64 號及曉大納言兩品種之生育期落葉性會影響單株莢重的累積,其原因是早生大粒品種因受生育期落葉影響,其莢果充實速率較低及有效充實期較短,而圓葉64 號及曉大納言兩品種則受生育期落葉影響,其莢果充實速率降低。 |
英文摘要 | The main purposes of this research are to investigate the relationship between the different growth stages and seed roduction for 12 varieties of three leaf abscission genotypes for adzuki bean, in order to select cross parent and develop selection. The results were summarized as follows: According to the timing of leaf abscission, delay leaf abscission (DLA), normal leaf abscission (NLA), and early leaf abscission (ELA) were discriminated. The accumulation of pod weight per plant is similar among three types of adzuki bean mentioned above no matter of developing stage in spring crop except for two ELA varieties, Chugoku red (CR) and Akatsukidainagon (AD). However, it was affected by the timing of leaf abscission in NLA and ELA genotypes in fall crop. Besides, DLA genotype has the highest pod yield per plant than the others in both crop seasons. It might bring about the higher of filling rate and the longer of filling period. Furthermore, the accumulation of pod weight per plant of Early large seed (ELS), a NLA variety, was decreased by lower of filling rate and shorter of filling period. On the other hand, its accumulation in two ELA varieties, Round leaf 64 (RL64) and Akatsukidainagon (AD), was only resulted from lower of filling rate. |
