Potato yield and tuber quality as affected by gibberellic acid and zinc sulfate

Abstract Obtaining high potato (Solanum tuberosum L.) tuber yield through increased number and weight of quality tubers is important for farmers while the quality factors are of interest for food processing industries. Potato processing industries require high quality tubers having the highest possible dry matter, starch and protein contents. A two-year field study was carried out as a factoria...

High temperature injury and auxin biosynthesis in microsporogenesis

Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High temperature (HT) injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to HT. I and my colleagues recently demonstrated that HT causes cell proliferation arrest and rep...

Effects of Salt Stress on Mustard as Affected by Gibberellic Acid Application

The effects of gibberellic acid (GA3) on growth, physiology and yield of salt-stressed mustard (Brassica juncea L. Czern & Coss) cv. Varuna plants were studied. The stress imposed by 25 or 50 mM NaCl reduced substantially leaf area, dry mass, leaf chlorophyll content, stomatal conductance and net photosynthetic rate 50 days after emergence. At harvest, although other yield components were gener...

Arachidonic Acid and Eicosapentaenoic Acid Metabolism in Juvenile Atlantic Salmon as Affected by Water Temperature

Salmons raised in aquaculture farms around the world are increasingly subjected to sub-optimal environmental conditions, such as high water temperatures during summer seasons. Aerobic scope increases and lipid metabolism changes are known plasticity responses of fish for a better acclimation to high water temperature. The present study aimed at investigating the effect of high water temperature...

Microsporogenesis and flower development in Eucalyptus urophylla × E. tereticornis

We compared microsporogenesis and flower development in Eucalyptus urophylla × E. tereticornis. In this study, although microsporogenesis and cytokinesis occurred simultaneously during meiosis of pollen mother cells, we observed a strong asynchronism in different anthers from a flower bud. The developmental period of microsporogenesis in anthers originated from the long thrum before the short t...
