Factors affecting Campsis radicans seed germination and seedling emergence
Krishna N. Reddy Southern Weed Science Research Unit, USDA-ARS, P.O. Box 350, Stoneville, MS 38776 The effects of environmental factors on germination and emergence of Campsis radicans seeds were examined in laboratory and greenhouse experiments. Campsis radicans pods produced numerous, papery, and small seeds (696 seeds/pod; 4 mg/seed). Seeds exhibited dormancy that was relieved (74% germinati...
متن کاملFactors affecting germination of Trichophyton mentagrophytes arthrospores.
Nutritional and environmental factors affecting germination of Trichophyton mentagrophytes arthrospores were investigated. Germination of dormant arthrospores occurred only in rich complex media such as Sabouraud dextrose broth or vitamin-free Casamino Acids. However, once activated, arthrospores were able to germinate under wide ranges of pH (5.5 to 8.0, optimal 6.5) and temperature (20 to 39 ...
متن کاملFactors Affecting Seed Germination and Seedling Growth of Terrestrial Orchids Cultured in Vitro
Terrestrial orchids (Orchidaceae) have become objects of concern to conservationists due to the plants' high sensitivity to changes in its environment (Rasmussen, 1995). Surface sterilization of mature seeds before germination eliminates barriers to germination; hypochlorites are most often used for this (Lindén, 1992). The barriers include an almost waterproof testa, and embryo integuments con...
متن کاملA STUDY ON SEED GERMINATION OF AVENA LUDOVICIANA AND THE EFFECTIVE FACTORS IN SEED DORMANCY BREAKING
Wild oat has two seeds in a spikelet that they have different physiological behavior in regard of seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for germination is 5˚C to 25 ˚C and optimal temperature is 15˚C. Both kinds of seeds showed the more germination rate in low temperatures so that 5 and 10˚C are better...
