Arid and semi arid areas of Balochistan are characterized by low and erratic rainfall and are prone to drought conditions which normally occur every three to four years. Th e prevailing drought is one of the most severe in its magnitude as annual rain (60-150 mm) has been well below average for a continuous period of four to fi ve years in most parts of highland Balochistan. Results from a long...
in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...
Drought detecting is a necessary aspect of drought risk management. It is generally performed usingdifferent drought indices that are effectively continuous functions of rainfall and other hydro- meteorologicalvariables. A number of drought indices have been introduced and used in various countries to date. In thecurrent research, four meteorological drought indices including the standardized p...
Kentucky bluegrass (Poa pratensis L.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. Oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. The objective of this study was to investigate whether Prohexadione-Calcium (Pro-Ca) may play a role in promoting ...
BACKGROUND Rice (Oryza sativa L.) is a highly drought sensitive crop, and most semi dwarf rice varieties suffer severe yield losses from reproductive stage drought stress. The genetic complexity of drought tolerance has deterred the identification of agronomically relevant quantitative trait loci (QTL) that can be deployed to improve rice yield under drought in rice. Convergent evidence from ph...

An Analysis of Drought Researches in Iran Extended Abstract: Iran is located the spatial geographical position in the south of the temperate region and north of the tropical region between the northern latitudes 40 to 25 degrees north and 65-44 degrees eastern along the seas, oceans and warm and great desert, on the other hand, with complex topography in the Alpine- Himalayas mountain belt ...
Maize crops grown during summer-rainy season in Asian tropics are prone to face both drought and excess moisture stress due uneven distribution patterns of monsoon rains in the region. We attempted to identify the relationship between drought and excess moisture tolerance through evaluation of a set of elite maize inbred lines, including lines with known performance under drought, excess moistu...
