The impact of phenylphthalamic acid (PPA) rates including 0 (PPA0), 1000 (PPA1000), 2000 (PPA2000) or 3000 (PPA3000) mg L-1 and perfect fertilizer rates including 0 (PF0), 100 (PF100), 200 (PF200) and 300 (PF300) mg L-1 was studied on vegetative and reproductive growth of ornamental pep...

This experiment was conducted to explore the reasons of difference between ‘Zard’ olive orchard with the poor vegetative growth rate and fruit set and orchard with suitable vegetative growth rate and fruit set in relation to some soil and plant factors during two seasons. Note that assumptions were based on the overall canopy greenness of the olive trees, so experimental orchards in which the p...

Fruit set and early development depends on endogenous hormone levels and gene expression related to fruit growth and development in cucumber (Cucumis sativus). In this study, the growth and development of cucumber ovaries and young fruits, endogenous hormones levels, and Csexpansin 10 (CsEXP 10) gene expressions in pollinated fruits and unpollinated ovaries were studied from -2 to 6 days post a...

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...

iran is the center of origin as well as variation for pomegranate (punica granatum l.). also, iran is one of the most important countries in the world in terms of pomegranate culture and production. monitoring morphological and physiological changes which occur during fruit growth and development is an important determining in orchard management decisions. the aim of the present research was to...

Fruit thinning is defined as the removal of certain flowers or clusters of flowers or individual fruitlets after fruit set and natural dropping have occurred.it improves fruit yield and quality and return bloom for the following year.There are three types of thinning namely:hand,mechanical and chemical.Chemical thinning is the most common type of thinning.Various chemicals are used for thinning...

Auxin is one of the most prominent phytohormones regulating many aspects of fleshy fruit development including fruit set, fruit size through the control of cell division and cell expansion, and fruit ripening. To shed light on the role of auxin fruit ripening, we have previously shown that Sl-ARF4 is a major player in mediating the auxin control of sugar metabolism in tomato fruit (cv MicroTom)...

Polyamines are organic polycations that have been associated with a large number of plant growth and developmental processes, such as pollination and fruit set. Most of the research has been done in horticultural plants, with only limited information existing for cotton. Numerous studies have correlated increased fruit set with increased polyamines concentration during flowering. Therefore in t...

Information from Literature Much has been published about pollination, pollinators, pollinizers, fertilization and fruit set in text books and periodicals. The definitions are not difficult. Pollination is the movement of pollen among compatible flowering plants (cross-pollination) or from anthers to stigmas on the same plant or different plants of the same clone (self-pollination). Many plants...
