摘要
以5种砧木分别嫁接‘瑞都红玉’和‘瑞都香玉’葡萄为试验材料,以接穗自根苗为对照,比较不同砧穗组合的树体生长特性、品质特性和内源激素动态变化规律,为葡萄适宜砧穗组合的筛选提供理论基础和参考依据。结果表明(1)以SO4、5BB和110R为砧木的接穗品种生长量大于以3309M和1103P为砧木的,但是110R小脚现象严重。(2)以SO4和5BB为砧木提高了‘瑞都香玉’的果实成熟度,5种砧木均显著提高了‘瑞都红玉’的可滴定酸含量,降低了固酸比,提高了‘瑞都红玉’的口感酸甜平衡性。(3)新梢生长期和转色期是促生长类激素分泌的高峰期,以110R和SO4为砧木的组合叶片和新梢中激素含量水平较高,以5BB为砧木的组合新梢中含量较高,且其叶片和新梢的ZR/GA3在新梢生长期处于高水平。‘瑞都红玉’/SO4在新梢生长期的ABA含量最低,与其长势强相吻合。以SO4为砧木的组合ABA含量从转色期到果实成熟期不升反降,有利于新梢的二次生长。110R、SO4和5BB组合的ZR/GA3在新梢生长期和转色期高于3309M和1103P组合,ABA/ZR+IAA+GA3低于3309M和1103P组合。研究结果表明,冬葡萄和河岸葡萄的后代SO4和5BB砧木的嫁接亲和力强,其接穗在新梢生长期和转色期促生长类激素水平相对高,嫁接植株生长旺盛,果实品质优良。
Five rootstocks:3309M,1103P,110R,5BB and SO4 were used as rootstocks and two Vitis vinifera cultivars’Ruidu Xiangyu’and’Ruidu Hongyu’as scions to evaluate the vine growth characteristics,fruit quality and dynamic regularity of endogenous hormones for different scion-rootstock combinations.The results showed that(1)SO4,5BB and 110R enhanced vine growth,but Ruidu Hongyu/110 R’s scion thickness/rootstock thickness is 1.56,showed poor graft compatibility.(2)Both SO4 and 5BB improved the fruit TSS of’Ruidu Xiangyu’;all the rootstocks enhanced the fruit TA of’Ruidu Hongyu’,reduced the Brix/TA ratio and improved the fruit sweet-sour balance.(3)Higher levels of growth promoting hormones including ZR,IAA and GA3 were detected during shoot rapid growth and veraison than during first blooming and fruit ripening.The combinations with 110R and SO4 showed significant high promoting hormone content in both leaf and shoot;while the combinations with 5BB showed low promoting hormone content in leaf,but high promoting hormone content in shoot,and high ZR/GA3 ratio during shoot rapid growth.Compared with all the other combinations,’Ruidu Hongyu’/SO4 had the lowest ABA content during shoot rapid growth,explained its vigorous growth.Combinations with 110R,SO4 and 5BB showed higher ZR/GA3 ratio,lower ABA/ZR+IAA+GA3 than combinations with 3309M and 1103P.ABA contents of combinations with SO4 declined during growing season,prompting the shoot growth during the second growth peak.On the contrary,ABA contents of combinations with 3309 M and 5BB were at high level during the growing season,impaired the vine’s growth.Above all,the offspring of V.berlandieri Planchon×V.riparia Michixi(SO4 and 5BB)showed good graft compatibility with Vitis vinifera,promoted scion growth,fruit quality and taste.
