Flowering phenology and wind-pollination efficacy of heterodichogamous Juglans mandshurica (Juglandaceae).

abstract：BACKGROUND AND AIMS:Lessons from above-ground trait ecology and resource economics theory may not be directly translatable to below-ground traits due to differences in function, trade-offs and environmental constraints. Here we examine root functional traits within and across species along a fine-scale hydrological gra...

abstract：BACKGROUND AND AIMS:Reciprocal herkogamy, including enantiostyly and heterostyly, involves reciprocity in the relative positions of the sexual elements within the flower. Such systems result in morphologically and, since pollen is deposited on and captured from different parts of the pollinator, functionally distinct f...
