Solitary Bees as Alternative Pollinators of Pennsylvania Fruit Crops
Introduction Pollination is a pivotal, keystone process in almost all terrestrial ecosystem food webs: it supports global and sustainable productivity in agriculture and forestry, and maintains the biodiversity of plant and animal life. Bees are the most important pollinators, but bee declines in abundance and species richness have been documented on 4 continents. Almost 100 crop species in the...
متن کاملWild pollinators enhance fruit set of crops regardless of honey bee abundance.
The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We found universally positive associations of fruit set with flower visitation by wild insects in 41 crop systems worldwide. In contrast, fruit set increased significantly with flow...
متن کاملEFFECT OF BEES-POLLINATORS IN BUCKWHEAT (Fagopyrum esculentum Moench) CROPS
The aim of the present study was to investigate the effects of bee pollination of buckwheat crops on the seed productivity and plant development. Six plots each 4 m2 in size were arranged in a buckwheat field. Four plots in the field were isolated by a net. Nucs with bees were placed in two of the plots (one per plot). Plant productivity, height of plants and number of branches per marked plant...
متن کاملImportance of pollinators in changing landscapes for world crops.
The extent of our reliance on animal pollination for world crop production for human food has not previously been evaluated and the previous estimates for countries or continents have seldom used primary data. In this review, we expand the previous estimates using novel primary data from 200 countries and found that fruit, vegetable or seed production from 87 of the leading global food crops is...
متن کاملZinc Nutrition of Fruit Crops
Zinc (Zn) deficiency is widespread throughout the world causing economic losses on a number of crops. Despite the fact that much information was generated during the last 20 years on Zn soil chemistry and its inorganic phase equilibrium, the mechanism controlling the amount of free Zn+2 present in the soil solution is not yet completely understood. This information is critical for the developme...
