Use of Excessive Waterlogging and Physiological Responses to Measure Genetic Variation in Loblolly Pine Waterlogging Tolerance
-Eleven sources of loblolly pine were studied for genetic variation in waterlogging tolerance and physiological responses to waterlogging. There were source differences in both though there were no correlations between them. Additional keywords: Pinus taeda, progeny tests, flooding, anaerobic metabolism The purposes of this study were to determine: a) if there was interspecific genetic variatio...
متن کاملWaterlogging Tolerance
More than one third of the world’s irrigated areas suffer occasional or more frequent waterlogging (Donmann and Houston, 1967). Waterlogging has been shown to limit wheat yields in many regions of the world; an area estimated at 10 million ha is waterlogged each year in developing countries (Sayre et al., 1994). Waterlogging occurs when rainfall or irrigation water collects on the soil surface ...
متن کاملTolerance of three grain legume species to transient waterlogging
Waterlogging reduces the yield of food crops. Tolerance to waterlogging could vary between and within species. This study aimed to quantify tolerance to soil waterlogging in two divergent genotypes of pea (Pisum sativum), two of lentil (Lens culinaris) and a grasspea (Lathyrus sativus) control at germination and during vegetative growth. Following germination, seeds were grown for 14 days in so...
متن کاملChanging desiccation tolerance of pea embryo protoplasts during germination.
Protoplasts were isolated from pea (Pisum sativum L. cv. Alaska) embryonic axes during and after germination to determine whether the loss of desiccation tolerance in the embryos also occurs in the protoplasts. At all times studied, protoplast survival decreased as water content decreased; however, the sensitivity to dehydration was less when the protoplasts were isolated from embryos that were...
متن کاملGenetic Structure of Salinity Tolerance in Rice at Seedling Stage
The Oryza sativa L. F8 population derived from a cross between salt tolerance cv. Ahlemi Tarom and salt sensitive cv. Neda was used in the study. Germinated seeds floated on water for 3 d, and after were transferred to float on Yoshida's nutrient solution for 11 d. two weeks after sowing, the seedling was transferred to nutrient solution containing 51.19 mM NaCl (electrical conductivity 6 dSm-1...
