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...
Generalized pollination systems and autonomous self fertilization are traits that have been linked with plant invasiveness. However, whether specialized pollination requirements pose a significant barrier to plant invasions is not yet clear. Likewise, the contribution of pollinators to the fecundity of facultatively self pollinating invasive plant species is poorly understood. We addressed thes...
Due to the rapid increased in the day by day users for spectrum cause scarcity of it. So due to its limitation and for the effective utilization of spectrum Cognitive Radio (CR) technology came into existence. This CR consists of its four main modules, which are: Spectrum sensing, mobility, sharing and management. Among which spectrum sensing is the keystone part, as due to the dependency of ot...
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) ...
in order to identify the best maturity time for excision of fertilized ovules in interspecific hybridization, intercrosses were made between two diploid (gossypium herbaceum and g. arboreum, 2n=26) and two tetraploid species (g. barbadense and g. hirsutum, 2n=52). flower morphology, growth rate of ovules and ovaries, as well as fiber growth pattern in various time scales post anthesis were reco...
The pollination biology of the cactus Pachycereus pecten-aboriginum was studied in a tropical location in western Mexico (ca. 18° N latitude) to compare with data from a northern population (ca. 28° N latitude). Throughout this range, the nectar-feeding bat Leptonycteris curasoae is resident within the tropics but migratory in its northern range. The hypothesis was tested that if a predictable ...
Nursery pollination in Caryophyllaceae species by Hadena and Perizoma moths has been extensively described in the last few decades. Evidence across multiple pairs of species shows that such pollination systems constitute relatively specialized interactions, shifting between parasitism and mutualism depending on the presence of effective co-pollinators. In this work, we describe a new specific S...
Objective: Environmental and economic challenges resulting from the application of nitrogen fertilizers have increased Concerns about its productivity in the agricultural systems. Thus an experiment in order to investigate ability SSM-Wheat for simulation growth and yield of wheat (cultivar N-87-20) in response to fertilizer nitrogen in the direction decrease Pollution environm...

Pollination and fertilization of canola flowers are the main factors of canola seed production. In order to study the effects of insect pollinators on seed quantity and quality of three chosen cultivars of canola, namly, S.L.M., Okapi and Talaye, a split plot experiment in a complete randomized block design with four replications was carried out in Isfahan region. Main plots consisted of canola...
