Although Apis mellifera is the dominant managed pollinator used to enhance crop production, variation of its foraging behaviour among crop-cultivars not considered as a factor influencing pollination success and, thus, yield. Almond production highly dependent on cross-pollination. Herein, we examined honey bees and pollen limitation in ‘Nonpareil’ ‘Independence’ cultivars. Nectar pollen-forage...

The mating system of plants widely distributed can change in native range but also non-native habitats. Oenothera drummondii, to the coastal dunes Gulf Mexico, has been introduced Europe, Africa, Asia and Oceania. Hand self- cross-pollination were performed determine compatibility compare fruit set, weight, seed set germination characteristics from natives non-natives populations a comprehensiv...

Distyly is a floral polymorphism that promotes cross-pollination through precise pollination. Psychotria mostly tropical genus of distylous Rubiaceae. Although widely studied in Brazil, some regions/species are still poorly explored, which hinders the understanding distyly system along greater geographical range. Here, we subtropical population brachyceras southern Brazil. For this, characteriz...

Breeding programs for horticultural tree crops focus on enhancing productivity, including developing tolerance to pests and diseases improving crop quality. Pollination services are often critical production, pollen parents can affect We do not know which produce highest quality offspring or, in self-compatible cultivars, how much of the comes from cross- versus self-pollination. quantified pro...

Bamboos are typical examples of highly synchronized semelparous species. Their mass-flowering events occur at supra-annual intervals but they sometimes flower on a small scale in off-years. If some bamboo ramets (culms) of a genet flower and die in off-years, whereas other culms of the same genet do not flower synchronously, the genet can still survive blooming in an off-year and could particip...

Pollination services are critical in entomophilous crops. Relationships between pollinator visits and fruit set mass complex optimal strategies to improve pollination poorly defined. We often do not understand what proportions of the crop result from self- or cross-pollination, how cross-pollination affects quality far cross-pollen is transported. quantified cross-paternity nuts partially self-...

Recently, genetically modified (GM) technology has been successfully used to reduce the cost and to enhance the profit in agriculture. Although GM technology brings many benefits for non-food crops, people still misgive the effects of GM products for the health and the environment. Furthermore, GM crops might affect food (non-GM) crops in the open environment. Hence, how to find strategies for ...

Understanding the reproductive biology is of great importance in development novel hybrids ornamental plants. Pollen fitness-related traits are crucial for pollination success any plant species including dendrobiums. The aim study was to determine and compare fitness ten commercial Dendrobium two indigenous species, D. crumenatum anosmum found Sri Lanka. We measured pollen viability, germinabil...
