摘要:

植物生长调节剂的应用是调控果树生长发育和提高果实品质的有效措施。本研究为探明花期喷施不同质量浓度芸苔素(EBR)和赤霉素(GA3)对蓝靛果(Lonicera caerulea)的影响,以主栽品种‘蓝精灵’为试验材料,分析了不同处理条件下蓝靛果植株的生长发育与果实品质指标。结果表明:2种生长调节剂均可有效促进其生长发育并提升果实品质。其中,30 mg⋅L-1 GA3显著促进新梢生长,其新梢长度较CK长72.95%;50 mg⋅L-1 GA3最有利于提高果实类黄酮含量与羟自由基清除率,其分别较CK高63.06%和14.67%;75 mg⋅L-1 GA3则能最大程度地提升抗坏血酸含量与DPPH自由基清除率,其分别较CK高27.10%和11.52%。0.1 mg⋅L-1 EBR显著提高叶片叶绿素相对含量和果实硬度,其分别较CK高30.55%和27.02%;0.3 mg⋅L-1 EBR+75 mg⋅L-1 GA3组合处理在增大叶面积(较CK高72.44%)、提升果实总花色苷含量(较CK高78.54%)和总酚含量(较CK高45.40%)方面效果最佳,并使果实总抗氧化能力达到峰值。综上所述,本研究证明了花期喷施适宜质量浓度的EBR和GA3是改善蓝靛果生长发育与果实品质的有效栽培措施,为芸苔素、赤霉素在蓝靛果栽培中的应用提供了理论依据。

Abstract:

Application of plant growth regulators is an effective strategy for regulating fruit tree growth and improving fruit quality. A field experiment was conducted to investigate the effects of brassinolide (EBR) and gibberellic acid(GA3) by foliar spraying on blue honeysuckle (Lonicera caerulea ‘Lanjingling’) during the flowering stage. The results showed that both growth regulators effectively promoted plant growth and fruit quality. Specifically, 30 mg⋅L-1 GA3 significantly promoted new shoot growth, with a 72.95% increase compared with the control(CK); 50 mg⋅L-1 GA3 was most effective for increasing fruit flavonoid content and hydroxyl radical scavenging rate, which rose by 63.06%and 14.67%, respectively, relative to CK. In contrast, 75 mg⋅L-1 GA3 maximized ascorbic acid content and DPPH radical scavenging rate, with increases of 27.10% and 11.52%, respectively, compared with CK. Application of 0.1 mg⋅L-1 EBR significantly increased leaf chlorophyll content and fruit firmness by 30.55% and 27.02%, respectively, relative to CK. The combined treatment of 0.3 mg⋅L-1 EBR and 75 mg⋅L-1 GA₃ yielded the optimal results, increasing leaf area by 72.44%, total anthocyanin content by 78.54%, and total phenolic content by 45.40%, respectively, compared with CK; this combination also maximized the total antioxidant capacity of the fruit. Therefore, spraying appropriate concentrations of EBR and GA₃ during flowering is an effective cultivation practice for improving the growth and fruit quality of blue honeysuckle. This study provides a theoretical basis for the application of brassinolide and gibberellic acid in blue honeysuckle cultivation.
