蔓生和矮生长豇豆器官生长相关与生产力研究

以曼生和矮生长豇豆，研究其干物质积累和分配、地上器官与地下器官、营养器官与生殖器官及生殖器官与同化器官的生长相关等。结果表明，两类长豇豆生育过程中植株和各器官干物质不断增加，均呈Ｓ型趋势变化。蔓生长豇豆比矮生长豇豆的干物质积累量高，蔓生长豇豆中白荚品种比青荚品种高。生育过程中根系分配的干物质越来越少，地下器官与地下器官的比例逐渐升高；随着干物质分配的中心由茎叶逐渐转移至花荚，生殖器官与营养器官的比

Studies on Organ Growth Relationship and Productivity in Vine and Dwarf Asparagus Bean

Dry matter accumulation and partition, growth relationship between upper and underground organs, and vegetative and reproductive organs in vine and dwarf asparagus bean Vigna unguiculata W.ssp. sesquipedalis (L.) Verd. ] were studied. The results showed that dry matter of plant and organs were increasing, in S trend, during growth and development. Dry mater accumulation of vine asparagus bean were more than dwarf asparagus bean, and that of white pod cultivar were more than green pod cultivar of vine asparagus bean. During growth and development, dry matter partitioned to root were decreasing, the ratios of upper/underground organs were increasing; with the center of dry matter partitioned shifted for stem and leaf to flower and pod, the ratios of reproductive/vegetative organs and reproductive/assimilatory organs were increasing. The three ratios of vine asparagus bean were higher than dwarfasparagus bean, and green pod cultivar were higher than White pod cultivar.
