Hybridization is one way to produce Hibiscus rosa-sinensis L. which have various shape and colour of flowers. However, this hampered by the possibility self-incompatibility in To identify simplest methods are used observing morphology anatomy fruit development, followed a descriptive analysis data that has been obtained. The results on crossing artificial pollination 103 flowers single pink sho...
INTRODUCTION There are many potential factors that can modulate bronchial reactivity, including exposure to allergens, viral infections, and medications. The aim of this study was to analyze the effect of grass pollination intensity on the bronchial reactivity in seasonal allergic rhinitis (SAR) patients subjected to subcutaneous allergenic immunotherapy (SCIT). MATERIAL AND METHODS This stud...
Diallel crosses among 6 Avena sativa L. and A. sterilis L. lines and introductions were used to evaluate the validity of the assumptions for the genetic model. Number of days to pollination, plant height at pollination and at maturity, as well as grain and stem protein percentages were evaluated. According to Griffing's method 1 the reciprocal mean squares for all the traits under study were si...

the present research was conducted with the purpose of studying self and cross-compatibility in some commercial cultivars of peach through field and microscopic studies in order to increase the quantity and quality traits of the product. the study was carried out in years 2010 and 2011. in a first experiment, the pollen germination of 10 cultivars of peach was studied in culture medium. the res...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
apricot (prunus armeniaca), palys an important role in fruit production industry in iran. irregular set of fruit, caused by either sterility of flower organs or incompatibility has been the main problem in apricot production over the years. in this study, it has been attempted to determine these phenomena for four apricot cvs. namely ‘shahroodi’, ‘nasiri’, ‘jahangiri’ and ‘noori’ through the me...
Seed set in banana is influenced by weather, yet the key weather attributes and critical period of influence are unknown. We therefore investigated during floral development for a better perspective seed increase. Three East African highland cooking bananas (EAHBs) were pollinated with pollen fertile wild ‘Calcutta 4′. At full maturity, bunches harvested, ripened, seeds extracted from fruit pul...
Detached pistils of Lilium longiflorum were labeled with d-glucose-U-(14)C 24 hours after anthesis and then sampled for the next 6 days to determine the appearance of label into exudate from the stylar canal and the stigmatic surface of the pistil. Results were obtained with unpollinated cv. Ace pistils and pollinated cv. Ace pistils, selfed or crossed (cv. Croft pollen). Limited data were also...
In red clover seed production, low yield is limiting the commercial exploitation of tetraploid clover. To explore if pollination factor for in clover, we investigated pollinator behaviour and plant reproductive success diploid (2x) cultivar ‘Rajah' (4x) ‘Amos' using honey bee hand approaches. We measured set at flower head level with increasing visitation rate bees (one bee, two open pollinatio...
