Plant response to environmental conditions: assessing potential production, water demand, and negative effects of water deficit
This paper reviews methods for analyzing plant performance and its genetic variability under a range of environmental conditions. Biomass accumulation is linked every day to available light in the photosynthetically active radiation (PAR) domain, multiplied by the proportion of light intercepted by plants and by the radiation use efficiency. Total biomass is cumulated over the duration of the c...
متن کاملPlant Response to Water-deficit Stress
Drought, a period of abnormally dry weather, results in soil-water deficit and subsequently plant-water deficit. The lack ofwater in the environment constitutes a stresswhen it induces an injury in the plant. Water deficit in the plant disrupts many cellular and whole plant functions, having a negative impact on plant growth and reproduction. Crop yields are reduced by 69% on average when plant...
متن کاملPlant responses to water deficit
Plant responses to water deficit are dependent on the amount of water lost, the rate of loss and the duration of the stressed condition. The characterization of a large number of genes induced by stresses involving water deficit has significantly improved understanding of the response. There appear to be several pathways for gene induction involved, and these are being elucidated by the analysi...
متن کاملResponse 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 کاملEffects of Superabsorbents on Growth and Physiological Responses of Date Palm Seedling under Water Deficit Conditions
Irrigation is an inevitable part of agriculture which determines crop yield and thus food security. In modern era of agriculture, crop yield is determined on the basis of crop production per unit of water-use instead of crop production per land unit area. Deficit irrigation is introduced as a strategy for controlling water resources that leads to water resource preservation. Date palm requires...
