Molecular transformation is commonly offered as a hope to overcome the apparent stagnation in crop yield potential. A basic understanding of the resource limits imposed on crops and the yield hierarchy going from gene expression to harvestable yield leads to a rather negative view that transformations of a few, or even of a complex of genes will result directly in major yield increases. Forty y...

This study was conducted Razakı grape variety (Vitis vinifera L.) and its vine which was aged 19 was grown on 5 BB rootstock in a vegetation period of 2014 in Afyon province in Turkey. In this research, it was investigated whether the applications of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), 1/3 CTR + STR, Boric Acid (BA), 1/3 CTR + BA, STR + BA, 1/3 CTR + STR...

climate change which is derived by increase of atmospheric co2 concentration and other greenhouse gases could have considerable effects on productivity of crops in the future. climate change impacts on chickpea yield were investigated and yield maps of dryland areas of zanjan province were provided. investigated scenarios were control scenario, in which simulated current situation, and climate ...

introduction the plant hormones such as salicylic acid and gibberellin can affect the quantity and quality of crops. external application of plant growth regulators as a strategy for improving salt tolerance in plants is discussed. foreign salicylic acid can regulate antioxidant enzyme activity and increase plant resistance to abiotic stresses. salicylic acid reduction due to ethylene through t...
