A Cyto-histological Study on Shoot Differentiation and Mesophyll Morphology of the Excised Lettuce (Lactuca sativa L.) Cotyledons as Affected by Light Conditions during Seedling Growth
Cell Cotyledon Lettuce Light Mesophyll Shoot differentiation
2009/8/6
Light quality and quantity of the environment, where lettuce seedlings were grown, affected the mesophyll tissue and the shoot formation in cotyledons excised and cultured in vitro. When cultured on M...
Promotion of Seedling Emergence of Paddy Rice from Flooded Soil by Coating Seed with Potassium Nitrate
Calcium peroxide Direct sowing Foliage leaf emergence Germination Paddy rice Pelleted seed
2009/8/6
Emergence and establishment of seedling of paddy rice sown into flooded soil are poor but promoted when seeds are coated with O2 generator CaO2. It has been commonly understood that this is because C...
Variation in Seedling Growth within a Rice (Oryza sativa L.) Cultivar and Its Effect on Seedling Salt Tolerance Evaluation
Embryo weight Rice cultivar/line Salt tolerance Seedling growth
2009/8/6
The variation of seedling growth, which may affect seedling salt tolerance, of 12 rice cultivars was examined based on the pattern of seedling fresh weight histogram. Some cultivars showed a normal di...
Effect of Sodium Chloride on Germination and Growth of Hexaploid Triticale at Early Seedling Stage
Germination Hexaploid triticale Salt tolerance Seedling growth
2009/8/4
Salt tolerance of ten cultivars of hexaploid triticale was assessed at the time of germination and at the early seedling stage in a laboratory experiment. Concentrations of the NaCl solutions employed...
