Fruit removal increases root-zone respiration in cucumber.
BACKGROUND AND AIMS Many attempts have been made to avoid the commonly observed fluctuations in fruit initiation and fruit growth in crop plants, particularly in cucumber (Cucumis sativus). Weak sinks of the fruit have been assumed to result in low sink/source ratios for carbohydrates, which may inhibit photosynthesis. This study focuses on the effects of low sink-source ratios on photosynthesi...
متن کاملCold temperature increases winter fruit removal rate of a bird -
We tested the hypothesis that winter removal rates of h i t s of wax myrtle, ~Vfjricu cerifern, are higher in colder winters. Over a 9-year period, we monitored M. cerifkru fruit crops in 13 0.1-ha study plots in South Carolina, U.S.A. Peak ripeness occurred in November, whereas peak removal occurred in the coldest months, December and January. Mean time to fruit removal within study plots was ...
متن کاملGibberellin Is Involved in Inhibition of Cucumber Growth and Nitrogen Uptake at Suboptimal Root-Zone Temperatures
Suboptimal temperature stress often causes heavy yield losses of vegetables by suppressing plant growth during winter and early spring. Gibberellin acid (GA) has been reported to be involved in plant growth and acquisition of mineral nutrients. However, no studies have evaluated the role of GA in the regulation of growth and nutrient acquisition by vegetables under conditions of suboptimal temp...
متن کاملSrap Markers for Fruit Shape in Cucumber
Fruit shape is one of the most important quality factors in many domesticated plants. In this study, we used bulked segregate analysis (BSA) to identify two sequence-related amplified polymorphism (SRAP) markers linked to fruit shape in cucumber (Cucumis sativus L.). A segregating F2 population of 130 plants from a cross (B-2-2×Y-3) of B-2-2 with long fruit shape trait and Y-3 with round fruit ...
متن کاملRoot cap removal increases root penetration resistance in maize (Zea mays L).
The root cap assists the passage of the root through soil by means of its slimy mucilage secretion and by the sloughing of its outer cells. The root penetration resistance of decapped primary roots of maize (Zea mays L. cv. Mephisto) was compared with that of intact roots in loose (dry bulk density 1.0 g cm-3; penetration resistance 0.06 MPa) and compact soil (1.4 g cm-3; penetration resistance...
