Tolerance 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 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 کاملUse 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 کاملDoes suberin accumulation in plant roots contribute to waterlogging tolerance?
Plants that are adapted to waterlogged conditions develop aerenchyma in roots for ventilation. Some wetland plant species also form an apoplastic barrier at the outer cell layers of roots that reduces radial oxygen loss (ROL) from the aerenchyma and prevents toxic compounds from entering the root. The composition of the apoplastic barrier is not well understood. One potential component is suber...
متن کاملSeedling tolerance to cotyledon removal varies with seed size: A case of five legume species
It is generally accepted that seedlings from large seeds are more tolerant to defoliation than those from small seeds due to the additional metabolic reserves present in the large seeds. However, information on the effects of amount of seed reserves (cotyledon removal) from seedlings resulting from large vs. small seeds on seedling growth and long-term survival in the field is limited. Five leg...
