Breeding system and pollination of two closely related bamboo species
An understanding of the breeding systems and pollination of agriculturally important plants is critical to germplasm improvement. Breeding system characteristics greatly influence the amount and spatial distribution of genetic variation within and amongst populations and influence the rarity and extinction vulnerability of plant species. Many woody bamboos have a long vegetative period (20-150 ...
متن کاملDifferentiation of two closely related species of the genus Empoasca (Hem.: Cicadellidae)
پیش‌تر، گونه‌ای زنجرک از مزارع چغندرقند استان اصفهان به اشتباه به نام Empoasca decipiens (Paoli) گزارش شده است که در این نوشتار نام صحیح آن به‌صورت Empoasca meridiana Zachvatkin اعلام می‌گردد. گونه‌ی اخیر دارای سینونیم شناخته‌تری به نام Empoasca punjabensis Singh-Pruthi می‌باشد. گونه‌های آسیایی خویشاوند گونه‌ی E. decipiens، براساس شکل پیگوفر (pygofer) ژنیتالیای نر ازهم تفکیک می‌گردند، به‌طوری‌ک...
متن کاملBreeding system and pollination ecology of two Abrus species (Fabaceae) from tropical West Africa
The pollination and breeding strategies of two Abrus species (A. precatorius L. and A. pulchellus Wall. ex Thw.) were comparatively investigated in Nigeria, West Africa. Observations were made on the phenology, floral morphology and architecture, breeding and pollination system, as well as flower-insect interactions. During 1999–2000, Abrus precatorius was observed to flower twice a year (April...
متن کاملPollination, breeding system, and genetic structure in two sympatric Delphinium (Ranunculaceae) species.
Two sympatric Delphinium species, D. barbeyi and D. nuttallianum, are ecologically and morphologically similar. However, D. barbeyi has multiple, large inflorescences while D. nuttallianum has a single, small inflorescence. These differences in floral display should result in greater intraplant pollen transfer in D. barbeyi, leading to higher rates of self-pollination through geitonogamy. Reduc...
متن کاملForaging segregation between two closely related shearwaters breeding in sympatry.
Trophic segregation has been proposed as a major mechanism explaining the coexistence of closely related animal taxa. However, how such segregation varies throughout the annual cycle is poorly understood. Here, we examined the feeding ecology of the two subspecies of Cory's shearwater, Calonectris diomedea diomedea and Calonectris diomedea borealis, breeding in sympatry in a Mediterranean colon...
