An investigation was carried out to study the impact of sowing date and row spacing on yield components and swelling factor of Plantago indica during 2009-10 & 2010-11 at Directorate of Medicinal and Aromatic Plants Research (DMAPR), Anand, Gujarat. Its an endeavour and a step forward to...

The seed character, dormancy breaking, high growth dynamic of one year old seedling and adaptability of, Cornus amomum, C. oblique, C. racemosa, C. drumondii, C. florida, C. sanguinea and C. walteri, were studied by test. Results showed that seed dormancy of six alien trees were basically broken...

The rate of transportation, introduction, dissemination, and spread of nonnative species is increasing despite growing global awareness of the extent and impact of biological invasions. Effective policies are needed to prevent an increase in the significant negative environmental and economic...

Seed mass and shape of grasses were analysed in a temperate flora containing 178 and 26 species belonging to C₃ and C₄ photosynthetic types respectively. The weedy character and the annual or perennial status were also considered. On the basis of the seed traits studied, three groups were...

The Bonin (Ogasawara) Islands are subtropical oceanic islands in the northwestern Pacific. Reflecting their ancient origins, previous studies on plants of the Bonin Islands reported evolutionary phenomena that are common to oceanic islands, such as high endemism and accelerated diversification. In...

Understanding seed characteristics and seedling establishment patterns is essential for the development of effective management strategies for invasive annual species. Dittrichia graveolens (stinkwort) has increased its range rapidly within California since 1995, yet its biology is not well...

Premise of the study: Because seeds have essential functions in the life cycle of plants, even subtle changes in their characteristics may have important demographic consequences. In this study, we examined whether potential changes in seed characteristics as a result of polyploidy or...

Can seed characters be used for predicting the presence of a persistent seed bank in the field? We address this question using ten cultivars of the crop Brassica napus, ten feral B. napus accessions originating from seeds collected in the field and nine accessions of the closely related ruderal...

In the present study, aerial biomass output and seed yield, viability, germination, and dormancy were evaluated in Melinis repens (Natal grass) growing at different locations in Aguascalientes, México. Four grazing excluded sites with high population of Natal grass were selected in the...

We analyzed 17 seed sources (seed stands) of Pinus wallichiana for variations present in cone and seed characters, scattered over natural distribution in north-west Himalayan states (Uttarakhand and Himachal Pradesh) of India. The significant variations were observed in cone weight, cone length,...
