摘要

为了提高果实品质,应用植物生长调节剂赤霉素(GA3)已成为一种重要的栽培管理方法。采用不同浓度的GA3溶液(25、50、75、100 mg L-1)喷施在花椒(Zanthoxylum bungeanum Maxim.;落果期和膨大期的芦花科()大树;在坐果期,喷施75 mg L-1 GA3最有效,纵径、横径、百粒重和果皮油囊数分别增加12%、5%、12%和42%;果实膨大期上述指标分别提高14%、11%、12%和35%。坐果期喷施100 mg L-1 GA3,总挥发油、刺激性物质、非挥发性醚提取物和总黄酮含量分别显著提高28%、6%、10%和3%;果实膨大期喷施75 mg L-1 GA3,各指标分别提高33%、27%、13%和11%。基于TOPSIS (Order Preference by Similarity to a Ideal Solution)的综合评价结果表明,浓度为75 mg L-1的GA3处理可以提高大红泡果实的品质,为该植物的栽培和管理提供了新的见解。虽然喷施GA3可以改变黄姜果实品质,但GA3处理对黄姜果实外在品质和内在品质的影响机制尚不清楚。

Improving the fruit quality of Sichuan-pepper (Zanthoxylum bungeanum Maxim.) ‘Dahongpao’ by optimized GA 3 treatments
To improve fruit quality, application of plant growth regulators as gibberellic acid (GA3) has emerged as a significant cultivation and management method. In the study, different concentrations of GA3 solutions (25, 50, 75, and 100 mg L-1) were sprayed on Sichuan-pepper (Zanthoxylum bungeanum Maxim.; Rutaceae) ‘Dahongpao’ trees at fruit setting and enlargement stages. Spraying 75 mg L-1 GA3 was most effective at both stages: vertical diameter, transverse diameter, hundred-grain weight, and number of oil sacs on the peel increased by 12%, 5%, 12%, and 42%, respectively, at fruit setting stage; and the aforementioned indexes increased by 14%, 11%, 12%, and 35%, respectively at fruit enlargement stage. Spraying 100 mg L-1 GA3 at fruit setting stage, the content of total volatile oil, pungent compounds, non-volatile ether extracts, and total flavonoids significantly increased by 28%, 6%, 10%, and 3%, respectively; spraying 75 mg L-1 GA3 at fruit enlargement stage, the indexes increased by 33%, 27%, 13%, and 11%, respectively. The comprehensive evaluation results based on Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) indicated that GA3 treatment in a concentration of 75 mg L-1 could improve the quality of ‘Dahongpao’ fruits, thereby providing novel insights for the cultivation and management of such plant. Although spraying GA3 may change fruit quality of Z. bungeanum, influencing mechanism of GA3 treatments on the external and internal quality of Z. bungeanum fruits remains unclear.
