in order to study stigma receptivity in peach cultivars : (‘makhmali’, ‘anjiri-ye-tabestane’, ‘anjiri-ye maleki’, ‘haj-kazemi’ and ’zoodras’) controlled pollination was done in both field and laboratory conditions. before pollination trials the in vitro germination of the pollen was tested in petridish. branches with adequate number of flowers were chosen for controlled pollination. self pollin...

Soluble sugar accumulation pattern and contents were studied in two Iranian melon cultivars, ‘Suski Sabz’ and ‘Jalali Zard’ (Cucumis melo L. Inodorous). Sucrose, glucose and fructose contents were determined in different mesocarp tissues of developing fruits during days after pollination (DAP). They were characterised by enhanced accumulation of glucose and fructose during early fruit developme...

to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

The influence of osmoticum treatments on early kernel development of maize (Zea mays L.) was studied using an in vitro culture method. Kernels with subtending cob sections were placed in culture at 5 days after pollination. Sucrose (0.29, 0.44, or 0.58 molar) and sorbitol (0, 0.15, or 0.29 molar) were used to obtain six media with water potentials of -1.1, -1.6, or -2.0 megapascals. Kernel wate...

The effects of two viviparous genes, vp(1) and vp(5), on development of the maize (Zea mays L.) embryo and endosperm were investigated. Differences between viviparous and normal embryos first appeared at 25 to 30 days after pollination. Increases in fresh weights indicated that viviparous began to grow more rapidly than normal embryos at that time. Amino acids and ethanol-soluble carbohydrates ...

18 The effect of the pollination time and of the pollen origin was studied in three self-compatible 19 and late-blooming almond genotypes in order to evaluate their effect on fruit set and yield. 20 The full self-compatibility of the three genotypes was clearly assessed as fruit sets after self21 pollination were similar to those obtained after cross-pollination with pollen from two 22 differen...

Germination of strawberry seeds from self- and cross pollination of 4 commercial cultivars were evaluated under mist and in vitro cultures. The study was conducted in McGill University in Quebec, Canada, during 1994 and 1995. Self-pollination of Chambly and Redcoat cvs., and cross pollination of Oka × Chambly as well as Redcoat × Veestar and their reciprocals were used. At maturity, fruits were...

For sexual reproduction of Allium hirtifolium, collected bulbs were planted in the field. In order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. Ovary development and seed setting of A. hirtifolium extraordinary were affected by pollination and there was a significant difference between mean effect of se...

BACKGROUND AND AIMS The pollination drop is a liquid secretion produced by the ovule and exposed outside the micropyle. In many gymnosperms, pollen lands on the surface of the pollination drop, rehydrates and enters the ovule as the drop retracts. The objective of this work was to study the formation of the pollination drop in Juniperus communis, its carbohydrate composition and the response to...
