The effect of twig architecture and seed number on seed size variation in subtropical woody species.
This study aims to determine the effect of twig (current year shoot) size on seed size variation and to test whether a seed size vs number tradeoff occurs for the twigs of subtropical broad-leaved species. Fruit-bearing twigs were sampled for 55 woody species (including 33 evergreen and 22 deciduous dicot species) from a southwest Chinese forest. Twig size, fruit size and number, and seed size ...
متن کاملNovel microsatellite markers acquired from Rubus coreanus Miq. and cross-amplification in other Rubus species.
The Rubus genus consists of more than 600 species that are distributed globally. Only a few Rubus species, including raspberries and blueberries, have been domesticated. Genetic diversity within and between Rubus species is an important resource for breeding programs. We developed genomic microsatellite markers using an SSR-enriched R. coreanus library to study the diversity of the Rubus specie...

متن کاملPhotosynthetic characteristics of invasive and noninvasive species of Rubus (Rosaceae).
The prolific amount of growth and reproduction in invasive plants may be achieved by greater net photosynthesis and/or resource-use efficiency. I tested the hypotheses that leaf-level photosynthetic capacity and resource-use efficiency were greater in two invasive species of Rubus as compared with two noninvasive species that have overlapping distributions in the Pacific Northwest. The invasive...
متن کاملThe scaling of seed size
1. Rees & Venable (2007; Journal of Ecology , 95 , 926–936) critically evaluated ideas of Moles et al. to explain the cross-species positive correlation between offspring size and adult size, arguing that they had misinterpreted the theoretical literature, and used cross-species patterns to constrain the evolution of life-histories. 2. In a reply to Rees & Venable, Westoby et al. (2009; Journal...
