Abstract:

To explore the optimum temperature, light intensityand water conditions for seed germination of Siphonostegia chinensis Benth.,seed germination experiment were carried out under different temperatures（5/15, 10/20, 15/25, 20/30℃）, different light intensity（14h light/10h darkness, complete darkness）and different concentrations（0％, 5％, 10％, 15％,...

Abstract:

With polyethylene glycol (PEG-6000), of 0% (CK), 5%, 10%, 15%, 25% used to simulate drought stress, and CaCl₂ concentration 0 (CK), of 15, 20, 25 and 30mmol/L as ion gradient of exogenous calcium, the effects of drought, exogenous calcium and the interaction between the two on the Datura seed germination, so as to explore the optimal...

Abstract:

Trees have a long juvenile phase before reproductive onset. This makes their breeding and studying floral development difficult. Precocious flowering using FT technology has shown promise. However, transgenic FT overexpression has significant negative pleiotropic effects. Hence, there has been interest in inducible FT expression for flower induction. Previously reported heat inducible expression of FT in... More

Abstract:

In the work, bean callus raised from a leaves of Bean common mosaic virus infected bean plant was obtained and adapted for the testing of antiviral activity of liposomal glycan-glycolipid complexes. Ganoderma adspersum glucans and Pseudomonas spec. rhamnolipids were constituents of liposomal compaunds. It has been shown that under the long-term cultivation (up to 3 months) in the... More
