Differential response to individual and combined stress treatments on Zingiber officinale Rosc. cv- varada with respect to its changes in yield, growth and gingerol content

Globally environmental stress plays a significant role in the growth and development of plants,Every stress alters the signal system and eventually resulting in an end response.Combination of stress treatments can both negatively or positively effect the plant. A few studies were conducted in combination of stress treatments in ginger. In the present study the effect of different individual stress treatments and their combined treatments on the concentrations of gingerols in improved ginger variety (Zingiber officinale cv-varada) were analyzed. The different stress treatments were attempted using salicylic acid and zinc Sulphate. Along with these two, drought is also taken as a third stress. The results of Individual and combination of stress treatments were obtained. The present study gives an idea about the effect of individual as well as combined stress treatments in both morphological (yield and growth parameters) and the gingerol content. This also gives a clear picture about cross tolerance in which one stress influenced the effect of another.
