Title

THE EFFECT OF SALT AND DROUGHT STRESSES ON GERMINATION OF THYME

Pages

  61-70

Abstract

 Considering the importance of medicinal plants, especially in drug industry and their shortage in nature, the study of different aspects of agronomy of these plants is of great value. THYME is one of the most important medicinal plants that due to containing timol and karakerol, has benefits including antibloated antityphoid, antidiphtheria and antipulmonary poisoning. The salt and DROUGHT STRESSes are known to be important factors in yield decrease of this plant. In order to study the effect of salt and DROUGHT STRESSes, two experiments were conducted separably in a completely randomized design on Shirazian THYME with four replications. The DROUGHT STRESS was applied in four levels with different osmotic pressures (0, 0.19, 0.41 and 0.99 Mega Pascal) using Polyethylene Glycol (Molecular weight 6000). SALT STRESS was also applied in four levels including 0, 30, 60 and 90 Mmol/Lit NaCl. After the exertion of treatments, counting of germinated seeds was continued daily for ten days, and characteristics such as GERMINATION percentage, GERMINATION speed, radicle and primary shoot dry weight, and radicle and primary shoot length were measured. The most GERMINATION percentage and speed belonged to control treatment (1.288) and the minimum belonged to 0.99 mega Pascal (1.058). There was a significant difference among different SALT STRESS treatments for GERMINATION speed, radicle length and primary shoot length. The most reduction in GERMINATION percentage, GERMINATION speed, radicle and primary shoot length was observed in 90 Mmol/Lit NaCl. Obtained results indicated that drought and SALT STRESS caused a significant decrease in GERMINATION percentage and GERMINATION speed, radicle and primary shoot length, as well as primary shoot and radicle dry weight.
