The economic value of insect pollinators is much higher than previously thought, according to researchers at the University of Pittsburgh and Penn State University. The team also found that ...
Eff ect of polyploidy and pollination methods on capsule and seed set of pansies (Viola × wittrockiana Gams)
garden pansy fertility self-compatibility
2015/3/19
Pansy, Viola × wittrockiana, is a popular ornamental plant. Eff ects of polyploidy on phenotype and four pollination
methods on capsule and seed set were studied using ten octoploid (2n = 8x) ...
A comparison of controlled self-pollination and open pollination results based on maize grain quality
chemical composition hybrids pollen pollination
2014/10/24
Maize (Zea mays L.) grain endosperm is triploid (3n), of which 2n come from the male (transferred by pollen) and only 1n from the female plant, thus a major impact of the male form can be expected on ...
Pollination dynamics, grain weight and grain cell number within the inflorescence and spikelet in oat and wheat
Cell Number Distal Grain Filling Potential Floret
2013/3/4
Oat (Avena sativa L.) and wheat (Triticum aestivum L.) vary in the structure of their inflores-cences and also in how pollination proceeds within the inflorescence. In both species the grain position ...
Verification for S-genotype of Japanese Pear ‘Housui’, ‘Chikusui’, ‘Shinseiki’ and ‘Seigyoku’ by Cross Pollination Test

The S-phenotypes (self-incompatibility phenotypes) of Japanese pear (Pyrus pyrifolia Nakai) ‘Chikusui’, ‘Shinseiki’, ‘Seigyoku’ and ‘Housui’ determined their S-genotypes by molecular markers were veri...
Sterility and Poor Pollination Due to Early Flower Opening Induced by Methyl Jasmonate
Anther dehiscence Flower opening in early morning Flower opening time Heat-induced sterility Methyl jasmonate Oryza sativa Pollination Sterility
2010/3/4
Flower opening in the early morning helps avoid sterility induced by heat stress at anthesis in rice (Oryza sativa L.). A pot experiment was conducted to reveal the effects of methyl jasmonate (MeJA) ...
Identification of the S-genotypes of several sweet cherry (Prunus avium L.) cultivars by AS-PCR and pollination
Self-incompatibility Prunus avium S-RNase AS-PCR pollination test
2011/1/10
Sweet cherry cultivars display a self-incompatibility system that restricts self-fertilization and fertilization between cultivars bearing identical S-alleles. PCR-based S-allele typing system for swe...
Bud Pollination for Production of Diploid Seedless Watermelon Using Partially Inactivated Pollen
empty seed laborsaving parthenocarpy soft X-ray irradiated pollen stored pollen
2010/11/24
Diploid seedless watermelons are presently produced by pollination with partially inactivated (soft X-ray irradiated) pollen. Bud pollination on the day preceding flowering was tested as a means of re...
Correlation between Viability of Pollination and Length of Basal Dehiscence of the Theca in Rice under a Hot-and-Humid Condition
Dehiscence of anther Flowering High temperature Hot-and-humid condition Pollination Rice Tolerance
2009/7/24
Anticipated global warming may increase the floret sterility of rice (Oryza sativa L.). For selection of genotypes tolerant to high temperatures during the flowering period, it is important to identif...
