Genetic diversity studies are essential to understand the conservation and management of plant resources in any environment. No detailed Random Amplified Polymorphic DNA (RAPD) were conducted study Geranium genetic diversity. Therefore, we collected analyzed thirteen species from nine provinces. Overall, one hundred twenty-five specimens collected. Our aims 1) assess among 2) is there a correla...

BACKGROUND AND AIMS Physical dormancy (PY)-break in some annual plant species is a two-step process controlled by two different temperature and/or moisture regimes. The thermal time model has been used to quantify PY-break in several species of Fabaceae, but not to describe stepwise PY-break. The primary aims of this study were to quantify the thermal requirement for sensitivity induction by de...

Seed production and patterns of sex allocation were studied in female and hermaphroditic plants in two gynodioecious populations of Geranium sylvaticum (Geraniaceae). Females produced more flower buds and seeds than hermaphrodites in one of the two study populations. The other female traits measured (pistil biomass, seed number per fruit, individual seed mass) did not differ between the gender ...
