Vegetative reproduction: Vegetative propagation is asexual plant reproduction that occurs in the plant's leaves, roots, and stems. This can happen as a result of plant fragmentation and regeneration of specific vegetative parts. Plants grow and develop naturally without human intervention in natural veg...
Following reproduction, male plants survive longer and grow more and so become predominant. In dioecious Angiosperms generally, male-biased ratios are characteristic of long-lived repeatedly flowering species and may be partly due to differential post-reproductive growth. It is postulated that male ...
All these group selection hypotheses postulate that the target of selection is the sex ratio at reproduction. Flowering plants have been the subject of relatively few sex ratio studies, although they have one considerable advantage over many animals, espe- cially mammals. In Angiosperms, the period...
Population dynamics with a mixed type of sexual and asexual reproduction in a fluctuating environment Populations of both sexually and asexually reproducing individuals exist in sympatry. In this study we try to elucidate the advantages of such a mixed ... R Barbuti,S Mautner,G Carnevale,... -...

Asexual versus Sexual Reproduction Many organisms can reproduce sexually as well as asexually. Aphids, slime molds, sea anemones, and some species of starfish are examples of animal species with this ability. Reproduction in bacteria | Asexual and Sexual reproduction | Prokaryotes |...
Life-history theory revolves around the idea that various activities, such as growth, maintenance, and reproduction, compete for limited resources. Hence, current reproduction may lead to a reduction in growth and survival, and consequen... MA Geber,TE Dawson,LF Delph - Springer Berlin Heidelberg...
In a second experiment to assess variation in sexual dimorphism across the life cycle, and whether this varied with resource availability, plants were grown in high and low nutrients and allocation to roots, aboveground vegetative growth and reproduction were measured at three developmental stages. ...

From the plant perspective, the rewards offered to pollinators must balance the rewards costs versus the invest- ment in reproduction1. Evidence of this is clearest when examining nectar rewards in relation to plant breeding systems. Most flowering plants are hermaphroditic (i.e. containing both ...
