摘要
在一定浓度范围范围内,用2.5×10-5mol/L和5×10-5mol/L浓度的茉莉酸甲酯和水杨酸甲酯喷雾处理挺立型野生稻植株(苗期),能有效地诱导其叶片内保护酶系活性的表达,2.5×10-5mol/L茉莉酸甲酯和水杨酸甲酯对SOD总活性的影响幅度变化较大,水杨酸甲酯和2.5×10-5mol/L的茉莉酸甲酯处理可明显诱导挺立型普通野生稻叶片POD、CAT的表达,增加其保护酶系的活性,进而增强植株抵抗不良环境的能力。
Plant induced resistance is important for prevention of adversity. The plant-signaling molecules salicylates and jasmonates play an important role in induced resistance pathways. Wild rice is an important genetic germplasm for rice breeding and impart certain eharacter-ristics to rice cuhivars in many cases. In a feasible concentration the express of protective enzymes of vanes from perpendicular Gaozhou wild rice (Oryza rufipogon) treated with exterior signal compounds salicylates and jasmonates can be induced , and the activity of protective enzymes could be increased.
