Abstract
In order to investigate the effect of Cenocarpus extract on the resistance of spinach to drought stress, a factorial experiment was conducted in the form of a randomized complete block design with two replications in the crop year 2019-2020 in the research greenhouse of Gonbad Kavous University. Experimental treatments including 5 levels of drought stress (0.10, 0.20,0.30,0.40 and 0.50 MAD) and 5 levels of extract (0, 2%,4%, 6% and 8%) were applied. The results showed that the greatest increase in consumption efficiency in the growth period and total water consumption was obtained from the 6% extract concentration with values of 1.045 μg/mL and 0.235 μg/mL, respectively. The efficiency of water consumption based on dry weight and the efficiency of water consumption on wet weight of the treatment without extract were obtained as 603.2% and 695.8%, respectively. The results of the comparison of the average weight of aerial parts under water stress and from the treatment of 2% extract were obtained. The maximum root length was obtained with 8.17 and 8.07 cm for 20% and 30% drainage, respectively, and the minimum root length belonged to the 50% moisture drainage treatment. The highest amount of chlorophyll, efficiency of consumption during the growth period and total water consumption were obtained from the control treatment, and also the highest efficiency of water consumption per dry weight and efficiency of water consumption per wet weight were obtained from the 2% extract treatment.
