Abstract

Background and Objectives: Ber (Ziziphus spp. ), is as one of the most important of tropical fruits that adapte to weather conditions of southern of the Iran and is cultivated in the provinces of Khuzestan, Hormozgan, Bushehr, Sistan and Baluchistan and county of Jiroft and kahnuj. Due to the climatic conditions of these areas such as low rainfall and high evapotranspiration, water deficit is one of the most important environmental factors that influences on cultivation of plants include of Ber in these areas and it has caused problems for farmers, and finding a solution to this problem is necessary. On the other hand, one of strategies for challenge with the water deficit problem and reduce the adverse effects of Drought stress on the growth and yield of crops and fruit trees in tropical regions is the application of the super absorbent materials. Materials and Methods: In order to evaluate the effects of Superabsorbent polymer on survival and vegetative growth of Ber (Ziziphus spp. ) grafted seedlings under Drought stress, an experiment with 3 irrigation levels as main plot including: 100, 80 and 60% of cumulative evaporation from pan class A, 4 levels of Superabsorbent polymer: 0, 40, 80 and 120g from A200 source as sub plot, carried out in split plat based on completely randomized block design with three replications on 36 Ber trees, during two years in Date palm and tropical fruits research center in Ahwaz. Results: Based on the results of variance analysis of data, different levels of irrigation and superabsorbent and interaction effect of them on survival and vegetative growth characteristics such as seedling height, root stock diameter, mean number of leaf and internodes in per stem length at 5% probability level is significant. Comparing the mean of different levels of irrigation, treatments of 80 and 100% of water requirement were in the same group and did not show any significant difference, but showed significant difference with 60% water requirement. On the other hand, the results showed that under Drought stress, application of different levels of irrigation and superabsorbent and interaction effect of them on some vegetative growth characteristics such as chlorophyll content, scion diameter and length of internodes in per stem length had no significant effect. Conclusion: Based on the finding of this research, the application 80g superabsorbent and irrigation with 80% of water requirement for each Ber seedling, saved 20% of water consumption, with no significant decrease of the survival and vegetative growth. Therefore, consumption of 80g superabsorbent at the planting time of Ber (Ziziphus spp. ) seedlings is recommended to farmers.
