摘要： Coordination of sugar transport and metabolism between developing seeds and their enclosing fruit tissues is little understood. In this study the physiological mechanism is examined using two genotypes of asparagus bean (Vigna unguiculata ssp. sesquipedialis) differing in pod wall and seed growth rates. Pod growth dominates over seed growth in genotype oZhijiang 121' but not in oZhijiang 282' in which a obulging pod' phenotype is apparent from 8 d post-anthesis (dpa) onward. Seed and pod wall growth rates and degree of pod-bulging were measured in the two genotypes together with assays of activities of sucrose-degrading enzymes and sugar content in pod wall and seed and evaluation of cellular pathways of phloem unloading in seed coat using a symplasmic fluorescent dye, 5(6)-carboxyfluorescein (CF). Activities of cell wall, cytoplasmic and vacuolar invertases (CWIN, CIN and VIN) were significantly smaller in pod walls of o282' than in o121' at 10 dpa onwards. Low INV activities were associated with weak pod wall growth of o282'. In seed coats, CF was confined within the vasculature in o282' but moved beyond the vasculature in o121', indicating apoplasmic and symplasmic phloem unloading, respectively. Higher CWIN activity in o282' seed coats at 68 dpa correlated with high hexose concentration in embryos and enhanced early seed growth. However, CWIN activity in o282' decreased significantly compared with o121' from 10 dpa onwards, coinciding with earlier commencement of nuclei endoreduplication in their embryos. The study shows genotypic differences between obulging pod' and onon-bulging' phenotypes of asparagus bean in sucrose metabolism in relation to the pathway of phloem unloading in developing seed coats, and to pod and seed growth. Low INV activity in pod wall corresponds to its shortened and weak growth period; by contrast, the apoplasmic path in the seed coat is associated with high CWIN activity and strong early seed growth.
