Fruit growth of cucumber in relation to assimilate supply and sink activity
TLDR
Assimilate distribution in Cucumis sativa, cultivar ‘Farbio’, was studied during 36 days after emergence of the inflorescense in the 5th axil to formulate a hypothesis that relates the dynamics of fruit growth to assimilate supply and the sink activity of individual fruits.About:

PART OF A SPECIAL ISSUE ON FUNCTIONAL-STRUCTURAL PLANT MODELLING Dry matter partitioning models for the simulation of individual fruit growth in greenhouse cucumber canopies
Dirk Wiechers,Katrin Kahlen +1 more
TL;DR: In this paper, an FSPM was developed which combined a model for architectural development, a biochemical model of photosynthesis and a model of assimilate partitioning, the last including a fruit growth model based on a size-related potential growth rate (RP).

Effects of Exogenous Plant Growth Regulators on Yield, Fruit Growth, and Concentration of Endogenous Hormones in Gynoecious Parthenocarpic Cucumber (Cucumis sativus L.)
Shoko Hikosaka,Nobuo Sugiyama +1 more
TL;DR: Results suggest that fruit load may have a greater influence on fruit abortion than that of PGRs, as well as that of other endogenous plant hormones.

Changes in Pickling Cucumber Yield and Economic Value in Response to Planting Density
TL;DR: The hypothesis that the density of 330000 plants ha -1 currently used by many growers could be significantly reduced without losses in economic value of the crop is supported and seed cost is proposed to be included in studies designed to identify optimum planting density.

Growth characteristic and sink strength of fruit at different CO2 concentrations in a Japanese and a Dutch tomato cultivar
TL;DR: Adjustments of cultural practices including increasing fruit number per truss and/or genetic approaches to enhancing fruit sink strength by breeding may improve fruit yields of Japanese cultivars under high source/sink conditions.
Journal ArticleDOI
The influence of fruit on the regulation of internal ethylene concentrations and sex expression in cucurbita texana
TL;DR: The results indicate that young developing fruits may send a signal that inhibits ethylene production, leading to the promotion of staminate flowers, and that, when fruits are no longer strong resource sinks, ethylene concentrations increase and promote pistillate flower production.

The Relationship Between the Rates of Carbon Transport and of Photosynthesis in Tomato Leaves
TL;DR: In this article, the carbon balance of a mature tomato leaf was measured over a 6-h period from a tomato leaf and the rate of carbon transport based on this carbon balance was measured under a range of net photosynthetic rates.

Assimilate Source-Sink Relationships in Capsicum annuum L. I. The Dynamics of Growth in Fruiting and Deflorated Plants
TL;DR: Net assimilation rates of fruiting plants exceeded those of deflorated plants, and these differences appeared to be associated with alterations in assimilate demand, indicating that leaves of these plants retain their photosynthetic capacity long after full expansion.
