to better understanding of drought resistance features including tolerance to chemical desiccation and transient photosynthesis under soil moisture stress in triticale in comparison with wheat and barley, an experiment was conducted during year 2009-10 in grizeh agricultural research station located in sanandaj. effect of three soil moisture regimes including irrigation in soil water potential ...

the effect on sugar beets of water and nitrogen movement in the soil under different water conditions was assessed over two years (2000-1) at the khorasan agricultural research center. three water treatments (no water stress, continuous stress and primary stress) and three n amounts (80, 160 and 240 kg n/ha) were investigated. the amount of moisture depletion in the water treatments was 50%, 80...

Injecting water into a coal seam to enhance the cohesive strength of coal and thus minimize and reduce the coal wall spalling risk must be considered in underground coal mining systems. In general, coal with low cohesive strength contains clay minerals which may affect the stability of coal by interacting with water. Therefore, the coupled effects of moisture content and inherent clay minerals ...

Stomatal response during exposure to SO(2) and O(3) and subsequent leaf injury were examined in plants of Pisum sativum L. ;Alsweet' grown in a peat-vermiculite medium in controlled environment chambers. Plants developing under moisture stress, induced by drying the medium to 50% of field capacity, exhibited greater stomatal closure during exposures and less than one-fourth the necrosis compare...

[1] The evaluation of the relationship between satellitederived vegetation indices (normalized difference vegetation index and normalized difference water index) and soil moisture improves our understanding of how these indices respond to soil moisture fluctuations. Soil moisture deficits are ultimately tied to drought stress on plants. The diverse terrain and climate of Oklahoma, the extensive...

This study was conducted to determine the effect of temperature and moisture stress on exsheathment process and infectivity of the infective larvae of the parasitic nematode Haemonchus contortus. Laboratory conditions were used in which infective (L3) of H. contortus were either subjected to gradually increasing temperatures, decreasing moisture or both. Post stress viability and exsheatment of...

Soil moisture is the vital component of the hydrological cycle and its variability is largely uncertain in the upcoming decades. In this paper the future projections of soil moisture changes over South Asia have been analyzed on both annual and seasonal basis from 2020-2050. The comparison of 24 CMIP5 (Coupled Model Inter comparison Project Phase 5) models with GLDAS (Global Lad Data Assimilati...

Drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. To evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. Cultivars with two-level white seedless and khosh...
