Journal of Pollination Ecology, 2013 More than 70% of world’s crops benefit from biotic pollination, and bees are their main pollinators. Despite the fact that some of these insects have been broadly studied, understanding the interactions between plant crops and their pollinators with a ...

Self-Pollinated Types and Ecological Adaptations of the Desert Plant Gymnocarpos przewalskii
PlantsIn desert plants, outcrossing is frequently limited by pollinator scarcity, leading to a certain percentage of self-fertilization. However, research on the ecological adaptations of self-fertilized seeds remains limited.

Effects of Self-Pollination in the Genus Pinus
, 1980 The problems of self-pollination among trees are a major concern to foresters. Silvicultural practices have an effect on the frequency of self-pollination.For example, a cut, such as a shelterwood or seed tree, reduces the number of individuals in the breeding population and increases the distance between individual trees.

Studies on self- and cross-pollination of olives under varying temperature conditions
California Agriculture, 1961 Investigations with Ascolano, Manzanillo, and Sevillano olive varieties show that chances of fertilization and fruit set are much greater after cross-pollination than after self-pollination.

Journal of Pollination EcologyBorago officinalis L. is an insect-pollinated crop valued for its seed oil. While described as self-compatible, the extent to which its reproductive success depends on pollinator-mediated cross-pollination and whether it experiences pollen limitation in

Domesticated pennycress is a self-pollinated crop
Abstract CoverCress is a new winter annual oilseed crop developed from field pennycress within the past 20 years. Field pennycress is commonly considered to be self-pollinated but little basic research has been published and there is some misalignment of conclusions.

Studies of Lythrum salicaria I. The Efficiency of Self-Pollination
American Journal of Botany, 1923 The conditions that exist in species with trimorphic flowers permit the investigation of the problems regarding the nature of sex-differentiation and the degrees of compatibility between male and female organs under very favorable circumstances. In these forms the morphological adaptations for cross-pollination are often decidedly correlated with ...
