Pollination is a well-studied and at the same time a threatened ecosystem service. A significant part of global crop production depends on or profits from pollination by animals. Using detailed information on global crop yields of 60 pollination dependent or profiting crops, we provide a map of global pollination benefits on a 5' by 5' latitude-longitude grid. The current spatial pattern of pol...
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...
Abstract This study aimed to evaluate the effect of combination between irrigation, semiprotected cultivation, and artificial pollination on yield, number fruits, mass yellow passion fruit grown under organic production. The experimental design was in randomized blocks set up split plots (2x2x2) with eight treatments four replications. plot consisted irrigation or rainfed conditions, second fac...
Pollination is critical to fruit production, but the interactions of pollination with plant resources on a plant's reproductive and vegetative features are largely overlooked. We examined the influences of pollination, irrigation and fertilisation on the performance of almond, Prunus dulcis, in northern California. We used a full-factorial design to test for the effects of pollination limitatio...
This study aimed to investigate the floral biology and pollination requirements of sesame (Sesamum indicum L.), cultivar CNPA G2. The study was carried out at Barbalha, State of Ceará, and consisted of two phases: floral biology and pollination requirements. Flowers were observed as for time of anthesis, lifespan and stigma receptivity, and were applied the following pollination treatments: ope...
Theresa M. Culley* Stephen G. Weller Ann K. Sakai Dept of Ecology and Evolutionary Biology, University of California–Irvine, Irvine, CA 92697, USA. *e-mail: [email protected] Although much emphasis has been placed on specialist pollination systems, attention is shifting towards systems in which plants are visited by a variety of pollinators [1,2]. Until recently, examples of generalist pollinatio...
Insects are the most important global pollinator of crops and play a key role in maintaining sustainability natural ecosystems. Insect pollination monitoring management therefore essential for improving crop production food security. Computer vision facilitated can intensify data collection over what is feasible using manual approaches. The new it generates may provide detailed understanding in...
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 ...
Linking Land Cover Data and Crop Yields for Mapping and Assessment of Pollination Services in Europe
Pollination is a key ecosystem service as many crops but in particular, fruits and vegetables are partially dependent on pollinating insects to produce food for human consumption. Here we assessed how pollination services are delivered at the European scale. We used this assessment to estimate the relative contribution of wild pollinators to crop production. We developed an index of relative po...
Objective: To know the variables of reproductive component materials for manual cross-pollination purposes, which search sexual synchrony is emphasized. Design/methodology/approach: Four were analyzed, two with white pulp and red pulp, about it unknown if they present self-incompatibility, in flowering also unknown. The phase that can shed light on its behavior analyzed Results: It was found st...
