摘要:
为明确外源6-苄氨基嘌呤(6-BA)、赤霉素(GA3)对蝴蝶兰品种甜格格的生理特性及花梗内源激素含量的影响并筛选最佳外源激素处理含量,本研究共设6个处理,分别为喷施100 mg/L 6-BA、150 mg/L 6-BA、200 mg/L 6-BA、100 mg/L GA3、150mg/L GA3、200mg/L GA3,对照组(CK)喷施蒸馏水。对甜格格的生长指标、生理特性、光合及叶绿素荧光参数进行测定与对比,并分析最佳激素含量下蝴蝶兰花梗发育3个阶段内源激素含量的变化。结果表明,6-BA、GA3可增加蝴蝶兰叶长和茎高,提高光化学淬灭系数(qP)、PSⅡ最大光能转换效率(Fv/Fm)、PSⅡ潜在光化学效率(Fv/Fo)、暗适应最大荧光产量(Fm)及表观电子传递速率(ETR),增强净光合速率(Pn),抑制非光化学淬灭系数(NPQ),且6-BA的整体处理效果优于GA3,其中,150 mg/L 6-BA为最佳处理含量。在150mg/L 6-BA处理下,蝴蝶兰花梗中内源激素含量随花梗发育呈动态变化。吲哚-3-乙酸(IAA)、茉莉酸(JA)、1-氨基环丙烷羧酸(ACC)主要作用于S1时期,6-苄氨基嘌呤、脱落酸(ABA)主要作用于S2～S3时期,不同时期激素含量差异较大,表明花梗发育过程受多种激素协同调控。本研究结果可为外源激素在蝴蝶兰栽培中的合理施用及对花梗生长的调控提供理论参考。
Abstract:
To clarify the effects of exogenous 6-benzylaminopurine (6-BA) and gibberellic acid (GA3) on the physiological characteristics and endogenous hormone content in pedicels of the Phalaenopsis variety Tiangege, and to determine the optimal concentration of exogenous hormones, this study established six treatments, including spraying with 100 mg/L 6-BA, 150 mg/L 6-BA, 200 mg/L 6-BA, 100 mg/L GA3, 150 mg/L GA3, and 200 mg/L GA3, with a distilled water spray as the control (CK). Growth indices, physiological characteristics, photosynthetic parameters, and chlorophyll fluorescence parameters were measured and compared. Furthermore, changes in endogenous hormone levels during the three developmental stages of Phalaenopsis pedicels under the optimal hormone concentration were analyzed. The results demonstrated that both 6-BA and GA3 promoted leaf length and stem height growth in Phalaenopsis spp., increased the photochemical quenching coefficient (qP), the maximum photochemical efficiency of PSⅡ(Fv/Fm), the potential photochemical efficiency of PSⅡ(Fv/Fo), the maximum fluorescence yield of dark-adapted leaves (Fm), and the apparent electron transfer rate (ETR), enhanced the net photosynthetic rate (Pn), and inhibited the non-photochemical quenching coefficient (NPQ). The treatment effects of 6-BA were generally better than that of GA3, with 150 mg/L 6-BA identified as the optimal hormone concentration. Under 150 mg/L 6-BA treatment, endogenous hormone levels in Phalaenopsis spp. pedicels exhibited dynamic changes as the pedicels developed. Indole-3-acetic acid (IAA), jasmonic acid (JA), and 1-aminocyclopropane-1-carboxylic acid (ACC) were primarily active during the S1 stage, while 6-BA and abscisic acid (ABA) were mainly active during the S2-S3 stages. Significant differences in hormone concentrations across these stages indicated that pedicels development was regulated by the synergistic action of multiple hormones. The findings of this study provide a theoretical reference for the rational application of exogenous hormones and the regulation of pedicels growth in Phalaenopsis spp..
