摘要: 为探究外源激素浓度对非洲菊(Gerbera jamesoniii)生长发育的影响,设置不同浓度(100、200、300 mg/L)的赤霉素(GA3)(T1、T2、T3)和6-苄氨基腺嘌呤(6-BA)(T4、T5、T6)叶面喷施处理,以清水为对照(CK,T7),通过测定非洲菊的生长、养分及生理生化指标,综合分析不同处理的效应,筛选最优处理方案。结果表明,T4现蕾时间较CK提前36 d;T3开花持续期最长(18.71 d),且花亭高度最大。外源激素对非洲菊生理指标存在显著影响,其中SOD活性、PPO活性与MDA含量变化趋势相近,均以T4最高。外源激素使非洲菊地下部生物量普遍降低,但根冠比除T5外均显著高于CK;不同处理对植株地上与地下部养分含量存在显著影响,整体表现为地上部养分含量高于地下部,且多数处理地上部全氮含量显著高于CK。基于主成分分析与隶属函数法的综合评价显示,各处理平均隶属值排序为T1(0.72)>T3(0.60)>T2(0.59)>T4(0.58)>T5(0.57)>T6(0.46)>T7(0.44)。

Abstract: To investigate the effects of exogenous hormone concentrations on the growth and development of Gerbera jamesonii, foliar application treatments with different concentrations (100, 200, 300 mg/L) of gibberellic acid(GA3) (T1, T2, T3) and 6-Benzylaminopurine(6-BA) (T4, T5, T6) were set up, with deionized water as the control (CK, T7). By measuring the growth, nutrient, physiological and biochemical indices of Gerbera jamesonii, the effects of different treatments were comprehensively analyzed to select the optimal treatment. The results showed that the budding time for T4 was 36 days earlier than that for CK; T3 had the longest flowering duration (18.71 d) and the greatest scape height. Exogenous hormones significantly affected the physiological indices of Gerbera jamesonii, with similar trends observed in SOD activity, PPO activity and MDA content, all of which were highest in T4. Exogenous hormones generally reduced the belowground biomass of Gerbera jamesonii, but the root-shoot ratios of all treatments were significantly higher than those of CK except for T5. Different treatments had significant effects on the nutrient contents of the aboveground and belowground parts of the plants, with the overall nutrient contents of the aboveground parts higher than those of the belowground parts, and the total nitrogen content of the aboveground parts in most treatments was significantly higher than that of CK. The comprehensive evaluation based on principal component analysis and the membership function method revealed that the order of the average membership values of each treatment was T1 (0.72) > T3 (0.60) > T2 (0.59) > T4 (0.58) > T5 (0.57) > T6 (0.46) > T7 (0.44).
