to evaluate the effects of presence of insect pollinators on quantity and quality of seeds of two common cultivars of onion (allium cepa l.), namely red azar shahr and yellow sweet spanish, an experiment in a factorial randomized complete block design was carried out at two sites. bulbs of equal size were planted with plant to plant 35 cm and row to row 50 cm spacing. at each site, experimental...
Parallel declines of wild pollinators and pollinator-dependent plants have raised alarms over the loss of pollination services in agroecosystems. A spatially explicit approach is needed to develop specific recommendations regarding the design of agricultural landscapes to sustain wild pollinator communities and the services they provide. I modeled pollination services in agroecosystems using a ...
Pollinators are the key point for successful pollination in most flowering plants around regions where 90% depend entirely on pollination. Majority of pollinating species wild, comprising bees, certain flies, wasps, moths, butterflies, thrips, beetles, bats, birds and other vertebrates, among them insect pollinators crucial. Fruit crops benefit an impressive way from pollination, there is a rem...
rapd markers through an application of 23 decamer primers were employed for genetic diversity analysis of some sweet cherry cultivars. bands with good resolution and high repeatability were selected for evaluations. the 23 primers produced 188 bands, among which, 153 were polymorphic. cluster analysis of the cultivars was performed based on the presence (1) and absence (0) of the bands, using j...
lants have evolved a variety of reproductive systems. The trees of some species, -L such as ash and ginkgo, are differentiated by gender, with both a female and a male individual required for seed production. Other species, such as cherries and almonds, ensure cross-pollination without separating individuals by gender: each plant is self-incompatible, so that stigmas cannot be fertilized by pol...
Experiments were conducted during 1996-1997 in Nough of Rafsanjan to evaluate double pollination on fruit set and development of pistachio nut. In the first experiment, Owhadi cultivar was pollinated by a combination of pollen from Beneh (P. mutica F&M), Atlantica (P. atlantica Desf) and Soltani (P.vera L.). In the second experiment, Owhadi cultivar was pollinated by pollen from Beneh, Atlantic...

The objective of this experiment was to evaluate self-compatibility of two late blooming almond cultivars and identification and introduction of suitable pollinizers from late flowering genotypes, and evaluation of pollen source effect on fruit characteristics to earn high quality nuts for Iranian almond industry. This experiment was carried out in order to determine the best pollinizer for two...
Pollination is an important early step in sexual plant reproduction. In Arabidopsis thaliana, sequential pollination events, from pollen adhesion onto the stigma surface to pollen tube germination and elongation, occur on the stigmatic papilla cells. Following successful completion of these events, the pollen tube penetrates the stigma and finally fertilizes a female gametophyte. The pollinatio...
