[In the Brassicaceae, targeted exocytosis to the stigmatic papillar plasma membrane under the compatible pollen grain is hypothesized to be essential for pollen hydration and pollen tube penetration. In contrast, polarized secretion is proposed to be inhibited in the stigmatic papillae during the rejection of self-incompatible pollen. Using transmission electron microscopy (TEM), we performed a...
Opuntia is the most diverse and widespread genus in Cactaceae; several species have broad distribution ranges successfully adapted to distinct habitats. One explanation for their success diversity of reproductive systems. macrocentra one common North American deserts. A previous work on a northern population documented that this has mixed-mating system receives low frequency pollinators. In sou...
Heat stress negatively affects pollination, fertilization, and consequently, the development of strawberry fruits. It was proved that foliar application titanium organic complex improved pollination fertilization processes some plant species, which resulted in better fruit development. Therefore, a three-year experiment designed to determine effect on consequently three remontant cultivars grow...
Onion thrips (Thrips tabaci Lind.) is one of the important factors which indirectly restrict the proper yield of onion (Allium cepa L.). Therefore, finding tolerant cultivars to onion thrips is important. Because of many small florets, cross pollination in onion which is a biennial plant by using polycross method for breeding is suitable and easy. To produce polycross seed, bulbs of 9 self poll...
Germination of strawberry seeds from self- and cross pollination of 4 commercial cultivars were evaluated under mist and in vitro cultures. The study was conducted in McGill University in Quebec, Canada, during 1994 and 1995. Self-pollination of Chambly and Redcoat cvs., and cross pollination of Oka × Chambly as well as Redcoat × Veestar and their reciprocals were used. At maturity, fruits were...
Ordubad 90 is one of the recently released apricot cultivars that was selected from the local apricot population of the north-west of Iran. Ordubad 90 has been evaluated in different environmental conditions and showed high adaptability. This apricot cultivar is high yielding and has the required properties for processing and induatrial purposes. Ordubad 90 had 13 ton ha-1 of fruit yield with f...
BACKGROUND/OBJECTIVE Despite potential benefits granted by genetically modified (GM) fruit trees, their release and commercialization raises concerns about their potential environmental impact, and the transfer via pollen of transgenes to cross-compatible cultivars is deemed to be the greatest source for environmental exposure. Information compiled from field trials on GM trees is essential to ...
One of the ways of haploid production is a cross between wheat and maize. Recently success has been achieved in this method, leading to the production of zygotes; these zygotes generally undergo elimination of maize chromosomes and thus lead to production of wheat haploid plant. The purpose of this study was to develop an efficient method of haploid production via maize pollination in short dur...
Self-incompatibility (SI) is a genetic mechanism in many flowering plants by which generative reproduction prevented. The self-incompatibility caused the functions of cell controlled genes called S or genes. results decreased pollination and ultimately yield loss. In apple (Malus domestica L.), multi-allelic S-locus. Approaches S-glycoprotein profiles allele-specific PCR methods using gene for ...
