Response of different species of Brassica to water deficit
Development of drought-tolerant cultivars is hampered by a lack of effective selectioncriteria. In this research, response of 36 genotypes of rapeseed from seven species of Brassicaincluding B. napus, B. rapa, B. juncea, B. carinata, B. oleracea, B. nigra and B. fruticulosa wasassessed under three moisture levels (no stress, mild stress and intense stress) in the field during2011-2012. Five dro...
متن کاملOsmotic Adjustment in Cotton (Gossypium hirsutum L.) Leaves and Roots in Response to Water Stress.
The relative magnitude of adjustment in osmotic potential (psi(s)) of water-stressed cotton (Gossypium hirsutum L.) leaves and roots was studied using plants raised in pots of sand and grown in a growth chamber. One and three water-stress preconditioning cycles were imposed by withholding water, and the subsequent adjustment in solute potential upon relief of the stress and complete rehydration...
متن کاملOsmotic Adjustment and the Growth Response of Seven Vegetable Crops following Water-deficit Stress
Growth-chamber studies were conducted to examine the ability of seven vegetable crops-‘Blue Lake’ bean (Phaseolus vulgaris L.), ‘Detroit Dark Red’ beet (Beta vulgaris L.), ‘Burgundy’ okra (Abelmoschus esculentus (Moench), ‘Little Marvel’ pea (Pisum sativum L.), ‘California Wonder’ bell pepper (Capsicum annuum L.), ‘New Zealand’ spinach (Spinacia oleracea L.), and ‘Beefsteak’ tomato (Lycopersico...
متن کاملIsolation of Brassica napus MYC2 gene and analysis of its expression in response to water deficit stress
Manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. MYC2 gene encodes a key stress-related transcription factor involved in Jasmonate (JA) and abscisic acid (ABA) signaling pathways in Arabidopsis. Brassica napus, as a globally important oilseed crop, is a close relative of Arabidopsis. In the present study...
متن کاملOsmotic Adjustment and Solute Constituents in Leaves and Roots of Water-stressed Cherry (Prunus) Trees
Tissue osmotic potential and solute constituents were evaluated in leaves and roots of well-watered and water-stressed Prunus avium L. × pseudocerasus Lindl. ‘Colt’ and Prunus cerasus L. ‘Meteor’. Osmotic potential at full turgor decreased in response to water stress for leaves and roots of both cultivars. For ‘Colt’, a cultivar with an indeterminate growth habit, decreased by 0.56 MPa and 0.38...
