Insect-pollinated crops provide important nutrients for human health. Pollination, water and nutrients available to crops can influence yield, but it is not known if the nutritional value of the crop is also influenced. Almonds are an important source of critical nutrients for human health such as unsaturated fat and vitamin E. We manipulated the pollination of almond trees and the resources av...

The honey bee is a major insect used for pollination of many commercial crops worldwide. Although the use of honey bees for pollination can disrupt the habitat, the effects on their physiology have never been determined. Recently, honey bee colonies have often collapsed when introduced in greenhouses for pollination in Japan. Thus, suppressing colony collapses and maintaining the number of work...

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...

Tropical biodiversity and associated ecosystem functions have become heavily eroded through habitat loss. Animal-mediated pollination is required in more than 94% of higher tropical plant species and 75% of the world's leading food crops, but it remains unclear if corridors avert deforestation-driven pollination breakdown in fragmented tropical landscapes. Here, we used manipulative resource ex...

Considerable infonnation has been developed on floral induction and the flowering process in Citrus in the papers which precede this one. Flower induction is a prerequisite to fruit production, so it is very important to have a clear understanding ofthe process. However, simply producing large numbers offlowers does not necessarily guarantee a subsequent large crop of fruit to harvest when they...

Pollen limitation of female fecundity is widespread among angiosperms, a signal that pollinators frequently fail to transfer pollen to fertilize all ovules. Recent surveys have suggested that pollen limitation is associated with floral specialization. This study uses a group of Antillean Gesneriaceae with contrasting pollination systems (bat, hummingbird, and generalist) to assess the premise t...

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...

Pollination is the process of transferring pollens to the stigma of conspecific plant and pollination ecology is the mutual relationship between flowers and pollinators. Pollination is a co-evolutionary process between flowering plants and pollinators, which dates back to millions of years. Insects are the most effective pollinators and have important role in pollination ecology. This review de...
