摘要
以2年生盆栽南丰蜜橘为试验材料,以未感染黄龙病的健康树作为对照,分析了感染黄龙病的病树叶片中脱落酸(ABA)、赤霉素(GA_(3))、吲哚乙酸(IAA)和玉米素核苷(ZR)的含量变化规律。结果表明,与对照相比,南丰蜜橘被黄龙病侵染后5~10天叶片中ABA含量显著降低,GA_(3)、IAA和ZR含量显著提高,可把激素含量变化作为黄龙病早期检测的一个辅助手段。
he contents variation tendency of abscisic acid(ABA),gibberellin(GA_(3)),indoleacetic acid(IAA)and zeatin nucleoside(ZR)in the leaves of two year old potted Nanfeng tangerine infected with Huanglongbing were analysed compared with the healthy trees without Huanglongbing.The results showed that,comparing with the healthy trees that without Huanglongbing,the ABA content decreased and the GA_(3),IAA and ZR contents increased in Nanfeng tangerine leaves significantly 5~10 days after the Huanglongbing infection,so the contents variation tendency of hormones could be used as an auxiliary means for early detection of Huanglongbing.
