Evaluation of compatibility on sweetpotato is very important to determine the crossing parents increase controlled cross-pollination. This research was aimed study level in cross-pollination based percentage normal seedlings obtained from crosses. The conducted at Kendalpayak Experimental Station ILETRI, Malang, Indonesia then followed by breaking seed dormancy and germination seeds obtained. g...

The objective of this experiment was evaluation of self-compatibility and identification, introduction and selection of late flowering genotypes as cultivars. This experiment was carried out in order to determine the best pollinator for two commercial almond cultivars, 'Shahrood 12' and 'Shahrood 21'. Applied pollinator cultivars were included pollen from 'Shahrood 21', 'Genco', 'Tuno', '5-15' ...

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...

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...

18 The effect of the pollination time and of the pollen origin was studied in three self-compatible 19 and late-blooming almond genotypes in order to evaluate their effect on fruit set and yield. 20 The full self-compatibility of the three genotypes was clearly assessed as fruit sets after self21 pollination were similar to those obtained after cross-pollination with pollen from two 22 differen...

for sexual reproduction of allium hirtifolium, collected bulbs were planted in the field. in order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. ovary development and seed setting of a. hirtifolium extraordinary were affected by pollination and there was a significant difference between mean effect of se...

BACKGROUND AND AIMS The study of specialized interactions between species is crucial to our understanding of processes in evolutionary ecology due to their profound effect on life cycles and diversification. Obligate pollination by a single wasp species is rare in Orchidaceae except in species with sexually deceptive flowers that are pollinated exclusively by male insects. The object of this st...

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...
