- CONSTRAINTS ON LEAF STRUCTURAL TRAITS IN WETLAND PLANTS
[作者:Vernescu, C; Ryser, P,期刊:American Journal of Botany, 页码:1068-1074 , 文章类型: Article,,卷期:2009年96-6]
- A plant species' ecology is associated with leaf economics, characterized, e.g., by photosynthetic rate, construction costs, and leaf life span. Specific leaf area (SLA, leaf area per leaf dry mass) is often considered t...
- POLLINATION ECOLOGY OF THE HIGH LATITUDE, DIOECIOUS CLOUDBERRY (RUBUS CHAMAEMORUS; ROSACEAE)
[作者:Brown, AO; McNeil, JN,期刊:American Journal of Botany, 页码:1096-1107 , 文章类型: Article,,卷期:2009年96-6]
- In a 3-yr study, we examined the pollinator guild and intersexual floral characteristics of the dioecious, perennial cloudberry (Rubus chamaemorus), which flowers in early spring. The findings contribute to our general U...
- LOCAL ADAPTATION IN EUROPEAN POPULATIONS OF ARABIDOPSIS LYRATA (BRASSICACEAE)
[作者:Leinonen, PH; Sandring, S; Quilot, B; Clauss, MJ; Mitchell-Olds, T; Agren, J; Savolainen, O,期刊:American Journal of Botany, 页码:1129-1137 , 文章类型: Article,,卷期:2009年96-6]
- We studied local adaptation to contrasting environments using an organism that is emerging as a model for evolutionary plant biology-the outcrossing, perennial herb Arabidopsis lyrata subsp. petraea (Brassicaceae). With ...
- REPRODUCTIVE IMPLICATIONS OF COMBINED AND SEPARATE SEXES IN A TRIOECIOUS POPULATION OF OPUNTIA ROBUSTA (CACTACEAE)
[作者:del Castillo, RF; Argueta, ST,期刊:American Journal of Botany, 页码:1148-1158 , 文章类型: Article,,卷期:2009年96-6]
- Opuntia robusta has hermaphroditic, dioecious. and trioecious populations. To enhance our understanding of this breeding system diversity, we compared the reproductive output of males, females, and hermaphrodites in a tr...
- OVULE NUMBER PER FLOWER IN A WORLD OF UNPREDICTABLE POLLINATION
[作者:Burd, M; Ashman, TL; Campbell, DR; Dudash, MR; Johnston, MO; Knight, TM; Mazer, SJ; Mitchell, RJ; Steets, JA; Vamosi, JC,期刊:American Journal of Botany, 页码:1159-1167 , 文章类型: Article,,卷期:2009年96-6]
- The number of ovules per flower varies over several orders of magnitude among angiosperms. Here we consider evidence that stochastic uncertainty in pollen receipt and Ovule fertilization has been a selective factor in th...
- GENETIC DIVERSITY AND STRUCTURE IN SEMIWILD AND DOMESTICATED CHILES (CAPSICUM ANNUUM; SOLANACEAE) FROM MEXICO
[作者:Aguilar-Melendez, A; Morrell, PL; Roose, ML; Kim, SC,期刊:American Journal of Botany, 页码:1190-1202 , 文章类型: Article,,卷期:2009年96-6]
- The chile of Mesoamerica, Capsicum annuum, is one of five domesticated chiles in the Americas. Among the chiles, it varies the most in size, form, and color of its fruits. Together with maize, C. annuum is one of the pri...
