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.
