Allometric relationships to estimate seasonal above-ground vegetative and reproductive biomass of Vitis vinifera L.

abstract：BACKGROUND AND AIMS:Natural selection and genetic drift are important evolutionary forces in determining genetic and phenotypic differentiation in plant populations. The extent to which these two distinct evolutionary forces affect locally adaptive quantitative traits has been well studied in common plant and animal sp...
