What is the process of cross-pollination? Pollination: "Pollination" part of the reproductive process in some types of plants. During pollination, male and female gametes (sperm and egg) combine. Successful pollination results in the development of seeds and/or fruit. ...
luteus cross, had a genome size approximately equal to the arithmetic mean of both parents (1.120 ± 0.004 pg), whereas the allohexaploid M. peregrinus had a genome size approximately double that of M.× robertsii (2.121 ± 0.017 pg). The offspring of crosses between tetraploid M. guttatus ...
Because monocarpic perennial plants have only one reproductive opportunity in their entire life, they need to ensure offspring production. Some plants reproduce both sexually and vegetatively, and vegetative reproduction could possibly compensate for seed production. Therefore, the role and significance of...
We studied the relationship between outcrossing distance and offspring fitness in a large population of the rare herbaceous perennial Gentiana pneumonanthe. The relative success of selfing and cross pollination with pollen from increasing distances from maternal plants, including an interpopulation cross,...
The inbreeding depression of selfed seedlings was exposed as lower initial height of seedlings, which resulted in lower seedling survival. These findings indicate that the population of S. laxa carries recessive deleterious genes and suffers inbreeding depression in selfed offspring....
styly, that are characterized by reciprocal herkogamy, function to increase the precision of animal-mediated cross-pollination, while reducing the costs that are associated with sexual interference between female and male sexual organs. The principal cost is pollen wastage through self-pollination....
We further self-pollinated the monecious individuals, and the offspring were all monecious in the following six generations of self-pollinations, which were designated as Gy14M-17, Gy14M-42, and Gy14M-63, respectively (Fig. 5b), indicating these 'gynoecy loss' mutations were stable. We...
Plants may adapt to alpine habitats by specialization in the reproductive strategy and functional aspects of their flowers and pollination systems. Alpine habitats reduce the opportunities for cross-pollination in a relatively high proportion of alpine plant species, and self-pollination may be favored ...
11 In order to understand the mechanism of how this widely consumed GM crop exerts its influence on the reproductive performance of mammals and their offspring, it would be necessary to perform complex research, including histological(a. 组织学的), genetic and embryo- toxicological(a.胚胎毒理学的...
[3]. However, tested cultivars had also a high variation in seed retention. To test whether the high variation within the populations is due to a wide genetic background, we also tested the offspring of a cross between two single plants ofFestuca pratensis. This family had a similar ...
