Abstract

 Water stress is one of the inhibitors in crops and drug crops seed GERMINATION and seedling growth. There are different ways to minimize the harmful effects of WATER STRESS tensions. SEED PRIMING is one of the popular and efficient techniques for increasing GERMINATION efficiency. The most important kind of priming is osmo priming (imbibing seeds in osmotic solutions with different osmotic pressure or potential); and hormo priming (to effect hormone compounds on seeds). This research was conducted to investigate the effects of salicylic acid (Aspirin), K CL, and NA CL on some morphological aspects, YIELD, and YIELD components of fennel (Foenicilum vulgar Mill) in WATER STRESS condition in laboratory and on research farm, College of Agriculture, University of Shahid Bahonar, Kerman, Iran in 1390 crop year. In lab; an experiment, as randomized complete block (Factorial design) with 3 replications was conducted. Fennel seeds treated with salicylic acid in 4 levels (0, O.1, 0.5, 1 m. molar concentration); K CL in 4 levels (0,-1, -1.5, -2 M pascal osmotic potential); NA CL in 4 levels (0, -1, -1.5, -2 M Pascal osmotic potential) For 24 hours in 20oC temperature. In salicylic acid treatments, the third level (0/5 m molar) had highest mean GERMINATION speed and seedling shoots and root length. In K CL treatments the second level (-1 Mp) had highest GERMINATION speed and seedling shoot and root length. In NA CL treatment -1.5 Mp treatment showed highest seedling shoot and root growth. In the farm experiment; the best priming treatments that were obtained in lab; were used and a randomized complete block in split plot design with 4 replications was conducted. Irrigation in 2 levels (no WATER STRESS, WATER STRESS) was as main plots; and different priming treatments in 4 levels (distilled water as control, NA CL with- 1Mp osmotic potential, K CL with -1.5 Mp osmotic potential, salicylic acid in 0.5 m. molar concentration) were used as subplots. The results showed that WATER STRESS and priming treatments, had significant effects on seed YIELD, biological YIELD, umbels number/pl, and umbellates number/ umbel in fennel; But plant height and harvest index were not significant. 1000 seed weight was affected by interaction effect of WATER STRESS × priming. WATER STRESS increased WATER EXTRACT percent, but decreased total YIELD WATER EXTRACT.
