Abstract:

以75MPa静水高压处理萌动的水稻种子12h,成苗后移栽至大田,研究高压处理后植株剑叶光合特性的变化。结果显示,静水高压处理后,粤香占和粤丰占种子的发芽率分别降低了14.4%和16.6%,成苗率分别降至对照的24.6%和21.9%,生长明显受抑制,幼苗的株高在35天左右才能追赶上对照。高压处理的粤香占剑叶在生育过程中的净光合速率(Pn)和表观量子效率(AQY)的总平均值分别比未处理的对照增加了9.2%和12.4%,而粤丰占则分别增加5.7%和17.4%。高压处理后两个品种的植株叶片不同生长时期的平均光合色素含量均高于未处理的对照,在生长后期的衰老过程中高压处理植株剑叶的色素含量和PSⅡ光化学效率Fv/Fm下降速率较各自的未处理对照缓慢。高压处理后两个水稻品种的生物量和单株产量分别比对照提高了8%~27%及7%~14%。提出高压处理可能作为一种新的选育品种的方法。
