Application of plant growth regulators (PGRs) is a novel strategy for allay of the adverse effects caused by biotic/abiotic stresses. However, no studies have vividly executed mathematic evaluation for the assessment of various PGRs on root phenotype traits (RPTs) against pollutants. In the present study, a microcosm hydroponic experiment was conducted to examine responses of RPTs under SCN- (0, 24, 96, and 300 mg SCN/L) stress in the presence of PGRs such as jasmonic acid (JA), indole-3-acetic acid (IAA), and sodium hydrosulfide (NaHS) in rice plants. Fuzzy synthetic evaluation was applied to determine the outcome of the effects of various PGRs on the RPTs under SCN- exposure. Root scanning results indicated that exogenous IAA and NaHS has the greater potential for improving the RPTs of rice seedlings under SCN- stress, while JA failed to uplift the RPTs in response to SCN- stress. Fuzzy synthetic evaluation indicated that in control plants (without SCN-), the effect of three PGRs applied on the RPTs is as follows: NaHS > IAA > JA. At 24 mg SCN/L, NaHS and IAA had consistent actuate in regulating RPTs of rice seedlings, while all PGRs amended have an affirmative impact on RPTs at 96 and 300 mg SCN/L. The present research highlights the utilization of contemporary mathematic method to screen the superior species of PGRs through the RPTs test of plants under pollutant belt |
