Multigenerational Effects of Flowering and Fruiting Phenology in Plantago Lanceolata
Phenological patterns of flowering and fruiting can be influenced by the effects of reproductive time on seed production. We propose here that these patterns are also influenced by phenological effects on offspring quality. Furthermore, we hypothesize that there are cross-generational trade-offs between parental and offspring components of parental fitness influencing the evolution of reproduct...
متن کاملReproductive ecology of the endangered Alpine species Eryngium alpinum L. (Apiaceae): phenology, gene dispersal and reproductive success.
BACKGROUND AND AIMS Eryngium alpinum (Apiaceae) is an endangered perennial, characteristic of the Alpine flora. Because the breeding system influences both demographic (reproductive success) and genetic (inbreeding depression, evolutionary potential) parameters that are crucial for population maintenance, the reproductive ecology of E. alpinum was investigated. Specifically, the aims of the stu...
متن کاملEffect of light and passage on cardiac glycoside production on cultured cell of Digitalis nervosa Steud & Hochst
Light is important for the production of metabolites by plant cell culture. It is therefore necessary to evaluate the light conditions with respect to exposure time. Both enhancement and inhibition have been observed depending on exposure time and species. Callus culture of D. nervosa was established and effect of light and passage on cardiac glycoside production was studied. In vitro cultures ...
متن کاملECOLOGY AND POPULATION BIOLOGY Phenology, Life Tables, and Reproductive Biology of Tetraleurodes perseae (Hemiptera: Aleyrodidae) on California Avocados
Tetraleurodes perseae Nakahara (Hemiptera: Aleyrodidae) is an exotic whiteßy in California that is aminorpest of avocados,Persea americanaMiller (Lauraceae). Fieldmonitoringover a 4.5-yr period (1997Ð2002) in a commercial avocado orchard in southern California indicated that T. perseae is probably univoltine, and adult densities show single distinct peaks each year around August. The only hymen...
