this experiment was carried out in 2003-2004 to determine fruit set patterns in four pistachio cultivars (akbari, ahmad aghaie, kalle ghouchi and ohadi) to find out the correlation between final fruit set and embryonic sac development, and as well between primary fertility and final fruit set. in a field experiment, inflorescence schematic shape and position of flowers (on inflorescence on the ...

Most Japanese plum-type cultivars are self-incompatible and therefore cross pollination is necessary to ensure fruit set. Moreover, pollen can directly affect fruit development process and quality.  This study was carried out to investigate the effect of 6 pollen sources (‘Goje Sabz’, ‘Simka’, ‘Shablon’, ‘Methley’, ‘Myrobalan’ and ‘Black Star’) on  fruit quantitative and qualitative characteris...

Abstract The Sidimpuan snake fruit ( Salacca sumatrana Becc.) tree flowers throughout the year. However, fruits are produced seasonally. level of production is directly related to flowering and set. A low formation results in a number that can be harvested. deeper understanding phenology set may help solve problem off-season production, focus this study. study was conducted village Palopat Mari...

this study was conducted under ahvaz, iran environmental condition during 2012 and 2013 growing seasons in order to investigate the influence of foliar application of potassium on some physiological and biochemical characteristics of three olive cultivars including ‘mission’, ‘koroneiki’ and ‘dezfuli’. potassium sulfate in different concentrations of 0, 1, and 2 g l-1 was sprayed twice on selec...

Ethylene production in apple fruit and protoplasts and in leaf tissue was inhibited by spermidine or spermine. These polyamines, as well as putrescine, inhibited auxin-induced ethylene production and the conversion of methionine and 1-aminocyclopropane-1-carboxylic acid to ethylene. Polyamines were more effective as inhibitors of ethylene synthesis at the early, rather than at the late, stages ...

high-density planting system is one of the effective methods for improving production and profitability of tree orchards. in this research, the effects of four planting densities (1904, 2666, 3137 and 4800 tree/ha) on annual shoot growth, tree yield, physicochemical properties of fruit and leaf mineral contents of apple (malus domestica borkh cv ‘granny smith’treegrafted on m26 clonal rootstock...

Plant cuticles on outer fruit and leaf surfaces are natural macromolecular composites of waxes and polyesters that ensure mechanical integrity and mitigate environmental challenges. They also provide renewable raw materials for cosmetics, packaging, and coatings. To delineate the structural framework and flexibility underlying the versatile functions of cutin biopolymers associated with polysac...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

Jujube (Ziziphus jujuba Mill.) fruit is an important medicinal plant in Iran. The harvesting time is a crucial for jujube fruit quality. Several characteristics of jujube fruit when harvested at four development stages; white mature (light green), crisp mature (white-red), fully mature (red) and fully ripe (dehydrated brown) were evaluated. Fruit weight, diameter, volume, pulp to stone ratio, f...
