WebFlower bud abscission in response to light quality appears to be controlled partly by the presence of leaves. The delay of bud abscission was positively correlated to the number of leaves being exposed to red light. Excluding the flower buds from exposure to red or far-red light, while exposing the remaining parts of the plants to these ... WebAbscission of flower buds, flowers, and immature fruits commonly accounts for low crop yields. Some species produce mature fruits from as many as half the flowers they bear, others from only a small fraction (Table 4.3). Kapok trees may produce more than 1,000 flowers for each fruit that grows to maturity (Stephenson, 1981).

High floral bud abscission and lack of open flower …

WebMany species of plants regularly abscise a large fraction of their buds, flowers, and fruit. Previous work has revealed that the production of excess fruiting structures allows a plant to retain high quality buds or fruits over those of low quality through a process termed "selective abortion." The aim of this proposal is to bridge an important gap in our … WebJul 26, 2003 · The flower bud abscission percentage was recorded every 5–10 days during kernel formation. Polyamine concentration declined during the period that coincides with that of kernel development, in both fruiting and non-fruiting branches, while significant bud abscission occurred from mid-July till late September in fruiting branches. ... how does interlock work

Regulation of floral organ abscission in Arabidopsis thaliana

WebThe alteration of heavy (“ON/bearing”) and light (“OFF/non-bearing”) yield in pistachio (Pistacia vera L.) has been reported to result from the abscission of inflorescence buds on high yielding trees during the summer, but the regulatory mechanisms involved in this bud abscission remain unclear.The analysis provides insights into the transcript changes … WebIt is suggested that light-controlled flower bud abscission in Lilium X ‘Enchantment’ is mediated by ethylene, and that an increase in ethylene evolution in darkness is a … WebDec 22, 2024 · Flower abscission typically causes significant financial losses by the horticultural landscape. Previous research has revealed that phytohormones, transcription factors, and other genes involved in floral development regulate the maintenance and mortality of flowers. ...
