The development of the leaf abscission zone in Ginkgo biloba trees and seedlings was studied. Leaves from Ginkgo seedlings were debladed to enhance anatomical changes in the abscission region. The development of an abscission layer was observed six days after deblading. The formation of the zone was not complete, but an abaxial to adaxial pattern of development was apparent. No evidence of sepa...

Plants utilize an innate immune system to protect themselves from disease. While many molecular components of plant innate immunity resemble the innate immunity of animals, plants also have evolved a number of truly unique defense mechanisms, particularly at the physiological level. Plant's flexible developmental program allows them the unique ability to simply produce new organs as needed, aff...

Abscission zone tissue of citrus was shown to have a higher rate of protein synthesis than tissue distal or proximal to it, based on the incorporation of leucine-1-(14)C. The proximal tissue had the slowest rate of protein synthesis. As the tissue approached abscission, the rate of synthesis in the abscission zone decreased and the differences in rate of protein synthesis between the 3 zones al...

Across the globe, tomato (Solanum lycopersicum L.) is a commonly used vegetable for culinary purposes. Despite its economic importance, production decreasing now days due to occurrence of various abiotic stresses like drought. Hence, it important understand mechanism drought tolerance sustain production. A field experiment was conducted with tolerant and susceptible genotypes or susceptibility....

The main objective of this work was to identify and classify genes involved in the process of leaf abscission in Clementina de Nules (Citrus clementina Hort. Ex Tan.). A 7 K unigene citrus cDNA microarray containing 12 K spots was used to characterize the transcriptome of the ethylene-induced abscission process in laminar abscission zone-enriched tissues and the petiole of debladed leaf explant...

The effects of 1-methylcyclopropene (1-MCP) and naphthaleneacetic acid (NAA) on fruit set and the expression of genes related to ethylene biosynthesis and perception and cell wall degradation in apple (Malus ·domestica Borkh.) were studied when applied during the normal chemical thinning period. 1-MCP at 209 mg L had a small negative effect or no effect on the final fruit set, depending on the ...

In recent years, herbaceous flowering potted plants have widely been used to be planted in garden area but these species might be also used as interior plants. Post production performance of flowering potted plants under interior conditions has become a research area of great interest. The aim of this work was to evaluate whether Salvia splendens may have a potential use as short-term colour so...

A decline in growth, flowering, and boll (fruit) retention is referred to as cutout in cotton (Gossypium hirsutum L.). Fruit load affects cutout, possibly through hormonal effects. Experiments were conducted to test the hypothesis that fruits are a source of abscisic acid (ABA) that moves into fruiting branches and growing points where it inhibits growth, flowering, and boll retention. Removal ...
