Xenia is the immediate effect of pollen on seed development after pollination. This study was conducted to investigate xenia’s effects Fe and Zn concentration in self- open-pollinated maize seeds. Eighteen hybrids derived from parents with varying concentrations were planted at Potchefstroom, Cedara Vaalharts South Africa for two seasons, 2017 2018. Open- self-pollinated seeds compared. Self-po...

Mungbean (Vigna radiata L.) is a cleistogamous plant in which flowers are pollinated before they open, which prevents yield improvements through heterosis. We previously generated a chasmogamous mutant (CM) mungbean in which open flowers are pollinated. In this study, we developed insertion/deletion (indel) markers based on the transcriptome differences between CM and Sulu-1 (i.e., normal flowe...

Potential decreases in crop yield from reductions in bee-mediated pollination services threaten food production demands of a growing population. Many fruit and vegetable growers supplement their fields with bee colonies during crop bloom. The extent to which crop production requires supplementary pollination services beyond those provided by wild bees is not well documented. Pumpkin, Cucurbita ...

BACKGROUND When applied at the correct plant stage and dose, herbicides are highly toxic to plants. At reduced, low herbicide doses (below the recommended dose) plants can survive and display continuous and quantitative variation in dose-survival responses. Recurrent (directional) selection studies can reveal whether such a phenotypic variation in plant survival response to low herbicide dose i...

The breakdown of self-incompatibility, which could result from the accumulation of non-functional S-haplotypes or competitive interaction between two different functional S-haplotypes, has been studied extensively at the molecular level in tetraploid Rosaceae species. In this study, two tetraploid Chinese cherry (Prunus pseudocerasus) cultivars and one diploid sweet cherry (Prunus avium) cultiv...

the level of self-compatibility of the 48 pre-selected apple cultivars, using their own pollen, the genetic capacity of flowering, flower-fruit conversion ratio, multiple fruit fall and bearing preservation during 4 successive biological growth stages were examined through two main treatments of self and cross pollination, in horticulture research station of kamalshahr in karaj (iran). the frui...
