Water deficit is one of the most important abiotic factors limiting growth, which adversely affect growth and crop production. In order to study the relationship between kernel size and phenological characteristics on grain yield, 46 local bread wheat genotypes along with four varieties were evaluated in randomized complete block design with three replications under irrigation and water deficit...

Drought events develop in both space and time and they are therefore best described through summary joint spatio-temporal characteristics, such as mean duration, mean affected area and total magnitude. This paper addresses the issue of future projections of such characteristics of drought events over France through three main research questions: (1) Are downscaled climate projections able to si...

Drought duration and intensity are expected to increase with global climate change. How changes in water availability and temperature affect the combined plant-soil-microorganism response remains uncertain. We excavated soil monoliths from a beech (Fagus sylvatica L.) forest, thus keeping the understory plant-microbe communities intact, imposed an extreme climate event, consisting of drought an...

  This study was conducted to assess the induced-changes in the content of total phenolics and individual phenolic acids, total and individual polyamines and some organic acids in the leaves of two important Iranian grapevine cultivars under different durations of drought stress, and to determine their involvement in grapevine drought tolerance. For this purpose, ‘Yaghuti’ as a drought-toler...

1. This paper introduces, and summarises the key messages of, a series of papers that emanated from a symposium on the Role of Drought in the Ecology of Aquatic Systems, held in Australia in 2001. 2. Defining drought hydrologically is problematic because the return times, intensity, duration and long-term trends in low-flow periods are specific to regions and times. Droughts may instead be refe...

Potato is the third most consumed crop globally after rice and wheat. It a short-duration crop, versatile in use, suitable for growing wide range of environments, its production increasing rapidly. The modern potato considered drought-sensitive it susceptible to yield loss because drought stress. Unfortunately, severity, frequency, extent have been around globe climate change. susceptibility ha...

Developing cultivars with traits that can enhance and sustain productivity under climate change will be an important climate smart adaptation option. The modified CSM-CERES-Pearl millet model was used to assess yield gains by modifying plant traits determining crop maturity duration, potential yield and tolerance to drought and heat in pearl millet cultivars grown at six locations in arid (Hisa...

Chickpea (Cicer arietinum); the second largest legume grown worldwide is prone to drought and various pathogen infections. These drought and pathogen stresses often occur concurrently in the field conditions. However, the molecular events in response to that are largely unknown. The present study examines the transcriptome dynamics in chickpea plants exposed to a combination of water-deficit st...

The process of leaf elongation in grasses is characterized by the creation and transformation distinct cell zones. prevailing turgor pressure within these cells one key drivers for rate at which divide, expand differentiate, processes that are heavily impacted drought stress. In this article, a turgor-driven growth model grass presented, combines mechanistic from basis with ontogeny leaf. Droug...
