摘 要:以5年生苹果烟富3/M26/平邑甜茶为试材,研究了萘乙酸(NAA)、乙烯及6–苄基腺嘌呤(6-BA)对坐果和13C、15N利用分配的影响。结果表明:在中心果直径5 mm时(盛花后14 d)喷施10 mg · L-1 NAA和600 mg · L-1乙烯利的植株坐果率显著低于对照,而喷施100 mg · L-1 6-BA的植株坐果率与对照差异不显著;NAA和乙烯利处理的植株13C和15N分配率规律一致,其果实13C分配率分别为1.11%,而根系和枝13C分配率和和1.22%,15N分配率分别为0.39%和0.33%,显著低于对照(9.12%和7.29%)

N分配率显著高于对照;NAA和乙烯利处理的植株Ndff值表现规律一致,提高了叶片、根系和枝对15N

的征调能力,降低果实对15N的征调能力;与对照相比,NAA和乙烯利处理的植株15N利用率显著增加了2.35和2.37个百分点,促进了根系、叶片和枝的生长和对氮同化物的征调能力,6-BA处理与对照差异不显著。

Abstract:5-year-old apple trees(Yanfu 3/M26/Malus hupehensis Rehd.)were treated with three different plant growth regulators to study the effect on fruit setting,which were α-Naphthalene acetic acid(NAA,10 mg · L-1),Ethrel(600 mg · L-1)and 6-Benzylaminopurine(6-BA,100 mg · L-1)respectively,and all the trees were labeled with 13C and 15N to determine the characteristics of carbon and nitrogen utilization. The results showed that fruit-set rate was obviously lower than control when sprayed with 10 mg · L-1 NAA and 600 mg · L-1 Ethrel 14 days after bloom,while no significant difference was found on spraying 100 mg · L-1 6-BA treatment. The 13C and 15N distribution to fruits of NAA and Ethrel treatments were 1.11%,1.22% and 0.39%,0.33% respectively,which were lower than control(9.12%,7.29%),while the 13C allocation to roots and branches were higher than control significantly.
