Abstract

Drought or insufficient water is considered as one of the most common limiting factors in global agricultural production. This study evaluated the effects of drought stress and foliar application of kaolin, chitosan, and glycine amino acid at different application times in Hyssop (Hyssopus officinalis L.) for two-year. The results demonstrated that extreme drought affects the growth and yield parameters of hyssop, such as decrease morphological traits as well as yield components, protein content and increase enzymatic antioxidants. The foliar application, especially with kaolin at flowering, caused the greatest changes in general, greatly enhanced the number of lateral branches, shoot dry weight, protein content by (13.62%), (6.15%), (7%) in the first year, respectively. In addition, chitosan had a beneficial effect on shoot dry weight too. Also, kaolin reduced the effects of oxidative stress in the plant by increasing its antioxidant capacity to. So that the enzymatic antioxidants CAT and POX enhanced by (32.48%), (43.35%) in the first year and by (5.95%), (13.18%) in the next year, respectively.
