WHEAT SEEDS (Triticum aestivum L.) PRIMING TO INCREASE GERMINATION QUALITY UNDER DROUGHT STRESS

Abstract

Priming is one of the practical method which is able to change the physiological condition, stimulate the drought tolerance mechanism in wheat genotypes under the water deficit and help the initial germination stage. The study aims at analyzing the effect of germination of wheat seeds under normal conditions and drought stress condition after applying priming treatments. This study used a Randomized Block Design (RBD). The data was collected, analyzed and processed using statistical analysis system version 9.1 software. Duncan multiple range test is used to find out the effect between treatments with the confidence level of 5%. There are 10 treatments: (1) control (2) aquadest, (3) CaCl2, (4) Gibberellin 50 ppm, (5) gibberellin 100 ppm,(6) control stress condition, (8) aquadest stress condition, (8) CaCl2 stress condition, (9) gibberellin 50 ppm stress condition, (10) gibberellin 100 ppm stress condition. The research was repeated three times. The observation parameters include the germination percentage, viability and vigor growth of wheat, sprout length, root sprout length, shoot sprout length and dry weight. The result and conclusions revealed that there was an effect of treatment on germination of wheat seeds, which priming with distilled water under stress condition can increase the value of growth speed significantly and simultaneous growth.
