Book Description
Several morpho physiological traits are traditionally used as screening criteria for drought tolerance such as relative water content (RWC), stomatal index, water use efficiency (WUE) etc. Crop WUE can be improved by optimizing crop transpiration. Several workers have proposed carbon isotope discrimination (CID), ash content and canopy temperature depression (CTD) as selection criteria for transpiration efficiency (TE), which may serve as the surrogate measures for improvement in grain yield.To identify suitable physiological traits useful in wheat breeding under water stress environment is the major thrust area of present investigation. For this, Durum and aestivum genotypes were selected from the breeding material of ARI, Pune (MS, India).Experimental trials on Triticum durum were conducted under three different water regimes viz. residual soil moisture stress (RSMS), post anthesis water stress (PAWS) as limited irrigation (LI) and well watered (WW) conditions.Data were collected for agronomical and physiological characters. Soil water balance model 'BUDGET' (Raes et.al. 2006) has been used for deriving WUE using meteorological, rainfall and irrigation data of (2004-05)and(2006)

Book Description
Wheat (Triticum aestivum L.) is the most important cereal crop for global food supply. Most of the wheat crop in developing countries including Nepal is either grown rainfed condition or under limited irrigation condition, thus water stress hits the wheat crop at different growth stages which thus limiting the grain yield. An experiment with 60 different genotypes of wheat was carried out in Nepal for the characterization for drought adaptation.The ANOVA (Analysis of Variance) revealed significant variation between environments and among the wheat germplasms for most of the drought adaptive traits. A wide range of variability was observed for the selected drougt adaptive morpho-physiological traits in moisture stressed and non-stressed environments. WUE was highly significantly correlated with biomass production. Nepalese cultivar Gautam showed a number of favorable drought adaptive traits. A number of landraces and advanced breeding lines showed high level of water use efficiency and other positive traits for drought adaptation.

Salinity and Water Stress

ISBN: 140209065X
Category : Science
Languages : en
Pages : 241
Book Description
Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income. Presenting recent research findings on salt stress, water stress and stress-adapted plants, this book offers insights into new strategies for increasing the efficiency of crops under stressful environments. The strategies are based on conventional breeding and advanced molecular techniques used by plant physiologists, and are discussed using specific case studies to illustrate their potential. The book emphasizes the effects of environmental factors on specific stages of plant development, and discusses the role of plant growth regulators, nutrients, osmoprotectants and antioxidants in counteracting their adverse affects. Synthesising updated information on mechansisms of stress tolerance at cell, tissue and whole-plant level, this book provides a useful reference text for post graduate students and researchers involved in the fields of stress physiology and plant physiology in general, with additional readership amongst researchers in horticulture, agronomy, crop science, conservation, environmental management and ecological restoration.

Book Description
The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.
