摘要

简介：众所周知，干旱胁迫会改变植物的生化活性，从而改变植物的生长发育。目的：由于缺乏对罗勒某些分类群的研究证据，因此有必要研究干旱胁迫与罗勒形态变化以及精油积累之间的关系。方法：在2020年进行了一项露地试验，以确定干旱胁迫对所选Ocimum物种形态和生化反应的影响。在灌溉（对照）和非灌溉（干旱胁迫处理）地块上种植了五种罗勒，即O.basilicum‘Genovese’、O.basilicum‘Ohre’、O.×africanum、O.americanum、O.selloi和O.sanctum‘Krishna’，并进行了两次块区复制。结果：灌溉对生产有积极影响。因此，灌溉地块的新鲜和干生物量产量分别高出39%和33%。在精油（EO）产量和主要化合物的EO组成的处理之间没有检测到显著的变化。然而，在灌溉处理下，观察到樟脑（O.×africanum）、橙花醇（O.americanum）和反式-β-石竹烯（O.sanctum‘Krishna’）的比例略有增加。另一方面，干旱胁迫增加了EO含量、多酚含量和抗氧化能力。此外，干旱胁迫对1,8-桉叶素（O.×africanum）和丁香酚（O.sanctum‘Krishna’）的比例有积极影响。在干旱胁迫下，EO含量仅略有增加，这与记录的显著减产无法相比。罗勒品种间也存在形态和生化变异。因此，罗勒和非洲罗勒分别获得了较高的生物量（616.33g/株）和EO产量（3.72ml/100g）。结论：灌溉对于最大限度地提高被测罗勒物种的生物量和EO产量至关重要。

Morphological and biochemical responses of selected Ocimum species under drought

Summary Introduction: Drought stress is known to change biochemical activities resulting in altered plant growth and development. Objective: Due to the shortage of research evidence in a certain taxa of basil, it is imperative to examine the relationship between drought stress and morphological changes as well as essential oil accumulation. Methods: An open field experiment was conducted in 2020 to determine the effects of drought stress on the morphological and biochemical responses of selected Ocimum species. Five basil species, namely O. basilicum ‘Genovese’, O. basilicum ‘Ohre’, O. × africanum, O. americanum, O. selloi, and O. sanctum ‘Krishna’ were grown under irrigated (control) and non-irrigated (drought stress treatment) plots with two block replications. Results: The result showed that irrigation had a positive effect on production. Consequently, fresh and dry biomass yields were higher on irrigated plots by 39% and 33%, respectively. No significant changes were detected between the treatments in essential oils (EO) yield and EO composition of major compounds. However, a slight increase in camphor (O. × africanum), nerol (O. americanum), and trans-β-caryophyllene (O. sanctum ‘Krishna’) ratios were observed under irrigation treatments. On the other hand, drought stress increased EO content, polyphenol content, and antioxidant capacity. Furthermore, drought stress had a positive effect on the ratios of 1,8-cineole (O. × africanum), and eugenol (O. sanctum ‘Krishna’). There is only a slight increase in EO content under drought stress, which is not comparable to the significant yield reduction recorded. Morphological and biochemical variations were also detected among basil species. Accordingly, higher biomass (616.33 g/plant) and EO yield (3.72 ml/100 g) among the species were obtained from O. basilicum ‘Genovese’ and O. × africanum, respectively. Conclusion: Irrigation is imperative for maximizing biomass and EO yield of tested basil species.
