Pantothenic Acid and Acetic Acid Utilization in Tomato Fruit-set.
Fruit-set in the tomato has been shown to be dependent upon the presence of mature leaves (3). The nature of the nutritive materials supplied by the leaves has been studied by use of excised tomato flowers cultured on an agar medium to which various nutrients have been added. Of the organic acids tested, all those participating in the Krebs tricarboxylic acid cycle were found to be effective in...
متن کاملGibberellin regulation of fruit set and growth in tomato.
The role of gibberellins (GAs) in tomato (Solanum lycopersicum) fruit development was investigated. Two different inhibitors of GA biosynthesis (LAB 198999 and paclobutrazol) decreased fruit growth and fruit set, an effect reversed by GA(3) application. LAB 198999 reduced GA(1) and GA(8) content, but increased that of their precursors GA(53), GA(44), GA(19), and GA(20) in pollinated fruits. Thi...
متن کاملThe role of auxin and gibberellin in tomato fruit set.
The initiation of tomato fruit growth, fruit set, is very sensitive to environmental conditions. Therefore, an understanding of the mechanisms that regulate this process can facilitate the production of this agriculturally valuable fruit crop. Over the years, it has been well established that tomato fruit set depends on successful pollination and fertilization, which trigger the fruit developme...
متن کاملFruit Cracking in Tomato
dom’ reached anthesis most rapidly, while plants of ‘Mathilde Gütges’ and ‘Merritt’s Supreme’ were the slowest to f-lower. Table 2 represents days to anthesis and not days to salable color. In general, plants were salable, based on sepal color, ≈10 days before anthesis, so subtracting 10 days from data in Table 2 gives forcing times (from start to sale) for these cultivars when a 62F (17C) mini...
متن کاملTomato Fruit Pericarp
The tomato fruit consists of a thick, fleshy pericarp composed predominantly of highly vacuolated parenchymatous cells, which surrounds the seeds. During ripening, the activation of gene expression results in dramatic biochemical and physiological changes in the pericarp. The polygalacturonase (PG) gene, unlike many fruit ripening-induced genes, is not activated by the increase in ethylene horm...
