“…No account was taken of the possibility of other sources of nutrition for normally maturing seeds in these studies on detached fruits. Later studies (4,16,17) of pea fruit development on the plant came to similar conclusions from examination of changes in various soluble and insoluble biochemical fractions during hull and seed development. The evidence here was of a correlative nature based partly on consideration of the different timing of pod and seed maturation.…”

Phaseolus vulgaris L. cv Seminole pods removed from the plant continued their development when incubated in suitable conditions. Seeds continued to grow and develop and pods and seeds passed through an apparently normal developmental sequence to dryness. Seed growth was at the expense of pod dry weight (DW) reserves. Losses of pod DW paralleled DW gains by seeds in detached pods and in pod cylinders containing a seed. The transfer activity was apparent only within the period 10 to 30 days after anthesis (DAA) with maximal activity between 15 to 20 DAA. This period corresponds to maximum pod growth and the attainment of maximal DW. Seeds are in only the early phase of seed growth at this time. No DW transfer was observed at developmental stages beyond 30 to 35 DAA when normal senescence DW losses in pods became evident and seeds were in the later phase of seed fill. Pods or pod cylinders remained green and succulent over the transfer period, later passing through yellowing and drying phases characteristic of normal development. DW transfer was dependent on funicle integrity and was readily detectable in pod cylinders after 7 days incubation. The DW transfer activity may contribute to continuing nutrition of seeds under conditions where the normal assimilate supply to seeds becomes limiting. Defoliation and water stress treatments applied to Phaseolus plants reduced seed yields but allowed persistence of seed maturation processes such that all seeds developing to dryness were capable of germination.Early this century it was suggested that reserves deposited in legume pods might be a source of nutrition for their enclosed developing seeds (7, 23, 30; reviewed in 17). A transfer of reserves of C or N was assumed from observation of losses by pods and gains by seeds. Pfenninger (23) that seeds of Vicia faba continued their development after removal from the plant, and several studies have reported continuing seed growth in detached pods of Pisum sativum (3,14,18,26) and Glycine max (19) cultured in aseptic conditions. In the latter, the potential role of pod tissues in supporting seed growth was not examined directly since contributing nutrition from the culture medium was involved to an unknown extent. Although soybean seeds do continue their maturation in detached pods, their growth is reported to cease upon pod removal (1).More recent studies (27) of the sources of nutrition for developing legume seeds show the greater proportion comes from translocated assimilates of vegetative origin and that fruit reserves provide only a limited supply. Temporary storage of incoming assimilates which may involve conversion to more useful forms has been suggested to account for the remarkable linearity of seed growth in the short term independent of diurnal or day to day fluctuations in supply in soybean (28). This argument is likely to find general application at least in species with relatively fleshy pods (6, 28) and complements other recognized functions ofpods in protecting the developing seeds, and acting as photo...

“…In Glycine max the proteins appear after the starch grains (Bils and Howell 1963) although a few grains, called ribonucleoproteins (Stephenson et al 1959), are present earlier. Most authors (Bisson and Jones 1932, McKee et al 1955, Bain and Mercer 1966 working on peas have observed a close similarity in the time of initiation and duration of protein and starch synthesis. The observations on the cotyledons of C. cajan and V. radiata (present work) agree with the above statement.…”

“…Also during development of the pea and other leguminous seeds there is a rapid rise in the starch content accompanied by a fall in sugars (Bisson andJones 1932, McKee et al 1955). Same phenomenon is observed in the presently studied plants.…”

“…The changes in the sugar content of growing peas have been studied by several investigators (1,6,8). All have found that the maximum sugar content is attained at a relatively early stage of ripening, much before the peas are considered ripe for canning.…”
