The occurrence of enzymes associated with bean leaf abscission was investigated in bean (Phaseolus vulgaris) flower reproductive organs in which catabolic cell wall events are essential during anther and pistil development. Cellulase activity was detected in high levels in both pistil and anthers of bean flowers before anthesis. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis followed...

Plant organ abscission is a common phenomenon that occurs at specific position called the zone (AZ). The differentiation and development of pedicel AZ play important roles in flower fruit abscission, which are great significance for tomatoes before harvest. Previous studies have reported some genes involved differentiation; however, regulating cell after remain poorly understood. In this study,...

Camellia oleifera is a woody oil tree with overlapping flower bud differentiation and fruit maturation. Therefore, mechanical harvesting of fruits leads to abscission. The present study investigated the effects number per on growth, yield, nutrient accumulation, fatty acid composition in C. oleifera. Here, we set different numbers by thinning flowers. Heavy (T2 T3) significantly reduced yield p...

Delayed cell separation historically was one of the first agricultural traits selected for by man. Successful collection of fruits and seeds of crops such as wheat (Triticum monococcum), rice (Oryza sativa), and a variety of legumes was only possible due to the selection for delayed fruit abscission or pod shatter in which seeds were retained on the stalk rather than rapidly shed. This selectio...

Natural and synthetic plant growth regulators have been used with increasing frequency to modify crop plants by changing the rate or pattern, both, of their responses internal external factors that govern development from germination. The use (PGRs) in modern horticulture is well established, particularly industrially advanced countries, application fast picking up developing nations as well. r...

The most part of hibiscus plants produces short life flowers that last one day. Therefore they are called ephemeral and flower senescence is usually associated with petal in-rolling and abscission. Flowers are well shaped and different organs can be easily separated, these characteristics make the hibiscus a good model system for flower senescence studies. The aim of this work was to identify m...
