Abstract
Under artificial climate chamber culture condition,standard hybrid A2,a kind of temperature-sensitive hybrid cotton,was used as material to study the effects and regulations of ABA and Ca2+/CaM messenger system on root growth of cotton seedlings under heat shock stress.The results showed that: ABA in cotton body was produced to improve the heat-resistance of cotton seedlings under high temperature stress condition.By spraying exogenous ABA or Ca2+,the heat-shock hazards on cotton seedling roots could be reduced,the root activity and bleeding intensity and root activity resilience could be increased,and the rate of root electrolyte leakage could be reduced.The interactive effects of ABA and Ca2+ were significant,the resistance of cotton seedlings to variable-temperature stress might be induced and play a role through the ABA and Ca2+/CaM messenger system.Sodium tungstate,LaCl3 or CPZ was the inhibitor of ABA or Ca2+/CaM messenger system,and the heat resistance of cotton seedlings could be diminished by spraying these exogenous inhibitors.The bleeding intensity of the base-stem in cotton seedlings,which could reflect the metabolic activity of root system before and after rehydration,might be used as an effective indicator to identify the heat tolerance in cotton.
