Abstract

To study the effect of WATER STRESS on some physiological characteristics of PINUS SEEDs including germination percent, mean germination time, germination speed, germination energy and vigor index, a factorial experiment in Completely Randomized Block Design (CRBD) with five treatments of water potential and two tree species was conducted. The water potential of the germination substrates (0, -2, -4, -6 and -8 bars) was conducted using PEG-6000 solutions on Pinus brutia Ten. and P. halepensis Mill. Seeds. The seeds were kept for 37 days in germinator (16 h photoperiod at 1000 lux and at 20±0.5oC). The results indicated that WATER STRESS had significant effect on seed physiological characteristics in both species. Decreasing water absorption potential from 0 to -8 bars, significantly reduced germination percent, germination speed, germination energy and vigor index in both species. The seeds of P. halepensis were more sensitive to deficiency of water availability in comparison with P. brutia seed.
