摘要: 为了了解不同栽培措施对降香黄檀叶片内源激素的影响,本研究通过铺设修枝、移植、钾肥、乙烯4个试验,分析各处理叶片激素含量特征。结果表明:修枝实验中,重度修枝处理IAA、GA3、ZR、ABA含量均最大,分别为69.849、6.619、8.805、77.998 ng·g-1。移植各处理中,去冠移处理IAA、ZR含量最高分别为73.195和9.472 ng·g-1,而其ABA含量最低为52.001 ng·g-1,GA3含量最高的为断根处理8.418 ng·g-1。IAA、ZR、GA3含量K1钾肥配比最高分别为75.188、8.383、6.127 ng·g-1;ABA最大含量71.082 ng·g-1为CK处理。乙烯试验中,CK处理的IAA、GA3含量最高分别为47.762、4.967 ng·g-1;E2.5%处理的ABA含量96.94 ng·g-1最高。E0.1%处理的ZR含量最高为9.378 ng·g-1。修枝对GA3/ABA和ZR/GA3影响较大,其最小值分别比最大值降低了29.7%、19.0%。移植对IAA/ABA、GA3/ABA影响较大,最小值比最大值依次降低了52.47%和51.47%。树干注射乙烯和钾肥对IAA/ABA、GA3/ABA影响较大,乙烯试验最小值分别比最大值降低了55.4%、49.2%,钾肥试验最小值分别比最大值降低了48.8%和37.1%。

Abstract: In order to study the effects of major cultivation strategies on the endogenous hormones of Dalbergia odorifera, the characteristics of leaf hormone accumulation of each treatment were analyzed by laying field tests. The contents of IAA, GA3, ZR and ABA in high-pruning treatment were the highest among three treatments of the pruning experiment. The contents of IAA(73.195 ng·g-1) and ZR(9.472 ng·g-1) in de-crown transplantation treatment were the highest and ABA content(52.001 ng·g-1) was the lowest among five treatments of the tree transplantation experiment, and GA3 content(8.418 ng·g-1) in root-pruning treatment was the highest among five treatments of the tree transplantation experiment. IAA, ZR and GA3 contents in K1 treatment were the highest among three treatments in K fertilizer application experiment. The maximum content of ABA was 71.082 ng·g-1 in CK treatment of K application experiment. In the ethylene application experiment, IAA and GA3 contents in CK treatment were highest among four treatments which were 47.762 and 4.967 ng·g-1. ABA content in E2.5% treatment was 96.94 ng·g-1. The ZR content of E0.1% was 9.378 ng·g-1, highest among the four treatments. The effect of pruning on GA3/ABA and ZR/GA3 was significant, and the low values were decreased by 29.7% and 19.0% compared with the high values, respectively. The effects of transplantation on IAA/ABA, GA3/ABA were also significant, and the low values were decreased by 52.47% and 51.47% compared with the high values, respectively. The effects of ethylene and K application fertilizer on IAA/ABA and GA3/ABA were significant. The low values of IAA/ABA and GA3/ABA were reduced by 55.4% and 55.4% compared with the high value, respectively in the ethylene application experiment. In the K fertilizer application test, the low values were 48.8% and 37.1% lower than the high values, respectively.
