Comparison of sugarcane yield in response to salt stress in Ahwaz climatical condition in Iran.

摘要

In order to investigate the effects of salt stress on recoverable sugar (RS) in sugarcane, a research was conducted in center of Amir Kabir Research Farm in Ahwaz, using a treatment method of split-plot based on randomized complete block design (RCBD), with four replications. This research was based on two factors such as sugarcane cultivars (CP 71-3002 and CP-4333) and different EC rates (2, 2-4 and 6 dS/m). The results showed that in terms of EC increasing, there were significant differences between cultivars and different EC rates on RS (0.613 in first harvesting and 0.231 in second harvesting). In normal condition, CP 71-3002 had higher RS than CP-4333, but CP-4333 had higher tolerance to salt stress than CP 71-3002.
