With regard to that some varieties of Brassica napus are grown increasingly in dry regions of Iran, it is important to examine drought-tolerance
physiological reactions of different varieties of Brassica napus to determine the effective tolerance reactions and select the most tolerant species to be grown in water-stressed regions of Iran.
further developments in drought-tolerance
technology across the world
There have been major plant breeding efforts to produce plants with increased drought-tolerance
to counteract the reduced availability of water, dwarf or compact plant forms to better fit containers and more crowded gardens, and a wider range of healthy produce that supports an improved lifestyle.
But its drawback is that, unlike ABA, it does not turn on all the "receptors" in the plant that need to be activated for drought-tolerance
to fully take hold.
Haf Elgar, a campaigner for Friends of the Earth Cymru, said: "Despite decades of research, there is still not a single commercially-available GM crop with increased yield, drought-tolerance
, salt-tolerance, enhanced nutrition or other beneficial traits, long promised by biotech companies.
For more than 25 years, he has been mining genetic diversity, found within the USDA Soybean Germplasm Collection, to fuel his drought-tolerance
It adds that genetically-modified soya, maize and cotton make up 95% of the total acreage of GM and none of the crops introduced so far have increased yield, enhanced nutrition, drought-tolerance
Gray and Norlander then chose plants for year-round color, ease of maintenance, and drought-tolerance
Results of the trial demonstrated that plants engineered for drought-tolerance
achieved significantly higher yields than the control plants under induced-drought conditions, and similar yields under non-drought conditions.
The Genuity DroughtGard Hybrids system combines germplasm selected for its drought-tolerance
characteristics, the drought-tolerance
biotechnology trait and agronomic recommendations.
We conducted this research on the basis of morpho- anatomical and physiological responses to evaluate in wheat drought-tolerance
traits in dry regions.
Our results and those of other partners we work with continue to show the yield-protecting benefits of our drought-tolerance
