pruning of the plant canopy and paclobutrazol application to the root zone are agronomic practices that improve harvest yield in mango (mangifera indica l.) orchards. to assess the effect of pruning and paclobutrazol treatment on the vegetative and reproductive development of ‘ataulfo’ mango, three pruning dates (20 april, 20 may, and 20 june) and three concentrations of paclobutrazol (pbz) (7....

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 ...

The vascularization of the pedicel in Marisol clementine (Citrus clementina Hort. ex Tanaka) has been characterized in relation to fruit growth. Phloem and xylem formation occurred during the first half of the period of fruit growth. Phloem cross-sectional area reached its maximum value by the end of fruitlet abscission, 78 d after anthesis (DAA), shortly after the rate of accumulation of dry m...

Since the biological effects of maleic hydrazide (MH) were first described by SCHOENE and HOFFMANN (4), a great many papers have appeared describing the effects of that compound on growth and flowering. NAYLOR (3) sprayed tobacco, maize and cocklebur with various concentrations ranging from .025% to .2%o and obtained either suppression or delay of visible flowering. WHITE and KENNARD (5) delaye...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

flowering and fruit production of ‘nagami’ kumquat is somewhat different from other citrus species because usually have three flowering peak in a year which can lead to producing fruits with different quality on a tree. considering the proper effect of paclobutrazol on raising citrus flowering, a pot experiment with three levels of paclobutrazol (zero, 0.1 and 0.5 g ai per tree) and six replica...

Alternate bearing (AB) is the process in fruit trees by which cycles of heavy yield (ON crop) one year are followed by a light yield (OFF crop) the next. Heavy yield usually reduces flowering intensity the following year. Despite its agricultural importance, how the developing crop influences the following year's return bloom and yield is not fully understood. It might be assumed that an 'AB si...

The rate and duration of apple fruit growth, cell division, and cell expansion, were considered in relation to within-tree factors affecting them. Fruit size at harvest was found to be related to the position of fruit on the spur, seed number, spur size, number of fruits set on the spur, and the date of flowering. The position of fruit on the spur, and spur size, were related to blossom size, b...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...
