Abstract

The present investigates were executed to decide the effects of citrus or banana peels extract on the growth and metabolic activities of two wheat cultivars Sakha 94 and Giza 168 grown under different drought stress conditions. Furthermore, to detect the drought tolerance of wheat cultivars and the roles of citrus or banana peels in alleviating drought stress, a pot experiment was carried out using drought stress levels and extracts of citrus 3% or banana peels 3%. The growth parameters of the two tested cultivars decreased with increasing drought stress levels especially at higher levels. This diminishing growth in Sakha 94 was related to the decline in soluble sugars and potassium in roots and spikes, soluble proteins in the three organs, and proline in shoots and spikes. In Giza 168, this reduction was coincided at 30% drought stress levels with the depletion in the soluble protein in shoots and spikes, potassium and proline in spikes. Exogenous application of citrus or banana extracts alleviates the inhibitory effects of drought stress in growth parameters and chemical constituents in two wheat cultivars. Potassium increased significantly as increasing drought stress levels with citrus and banana treatments in Sakha 94, while it was declined in Giza 168. Exogenous application of Citrus or Banana mostly increased anthocyanin, ascorbic acids in the two wheat cultivars while total phenolic compounds and flavonoids did not change.
