To test the germination capacity and its temperature dependence in Mediterranean plants, sixteen species representative of a diversity of habitats of the Balearic Islands were selected. The percentage of germination, the half-response time and the dormancy period of these species were studied at three alternating temperatures: 5-15 C, 10-20 C and 15-25 C. Large differences were found among spec...

this study was carried out in order to investigate on chromosomal behavior during meiosis in herbaceum (iranian endemic), arboretum species, f1 hybrids of two species and bc4 genotypes. the endemic varieties used in this study were semnan and shahreza (herbaceum) and vtdl as arboretum cultivar. f1s investigations showed that in the adjacent and alternative quadrivalents frequently but the bc4 o...

Hamiguitan Range is one of the wildlife sanctuaries in the Philippines having unique biodiversity resources that are at risk due to forest degradation and conversion of forested land to agriculture, shifting cultivation, and over-collection. Thus, it is the main concern of this research to identify and assess the endemic and endangered flora of Hamiguitan Range. Field reconnaissance and transec...

Kenya, an African country with major higher plant diversity, has a corresponding diversity of plant associations, because of the wide geographic distribution, diverse climatic conditions and soil types. In this article, all vascular plants of Kenya were counted based on the completed "Flora of Tropical East Africa (FTEA)", and all families and genera were revised using recent molecular systemat...
