摘要: 采用塑料大棚直播栽培,以鄂豇豆6号、鄂豇豆2号、鄂豇豆7号和美国地豆等4个豇豆品种为试验材料,在现蕾期以叶面喷施细胞分裂素(CTK)为处理,以清水为对照(CK),于处理后7 d(初花期)、喷后14 d(盛花期)、喷后28 d(盛荚期)、喷后42 d(终收期)对豇豆叶片光谱参数和叶绿素荧光参数进行测定。结果显示,随着喷施CTK处理时间的延长,豇豆各品种叶片光谱指数CRI1(类胡萝卜素反射指数)、ARI1(花青素的光谱反射指数)的变化呈下降—上升—下降的趋势,叶片NDVI(归一化差值植被指数)、WBI(水分指数)、PRI(光化学反射指数)呈上升—下降—上升的趋势,处理组与对照组之间均无显著差异。喷后28 d,豇豆各品种Y(Ⅱ) (实际光合效率)比未喷施对照组平均降低了1.92%,qP(光化学淬灭)比对照升高了1.37%;Fv/Fm(PSⅡ的最大光合效率)比对照降低了2.35%,处理组与对照组之间均无显著差异。

Abstract: Ejiangdou 6, Ejiangdou 2, Ejiangdou 7 and Meiguo Didou were used as research materials and cytokinin (CTK) was sprayed in the budding period on cowpea leaves, with the same amount of water as a control (CK). Spectral indexes and fluorescence parameters of cowpea leaves were determined after spraying cytokininon at 7 days (early flowering stage), 14 days (flourishing flowering stage), 28 days (flourishing podding stage), 42 days (final stage). The results showed, with the increase of processing time, the change trends of CRI1 and ARI1 of all cowpea varieties leaves were down-up-down, while NDVI, WBI and PRI were up-down-up and there was no significant difference between spraying cytokininon and the control. On 28 days after spraying cytokininon, compared with the control, qP increased by 1.37%, Y(Ⅱ) and Fv/Fm reduced by 1.92%and 2.35%, respectively, which had no significant difference from CK.
