ABSTRACT

Lavender is an aromatic-medicinal plant, cultivated in Greece and in Mediterranean basin in general. The aim of the current study was to investigate if the use of bio-stimulants could increase the yield of the flowering shoots and the essential oil content even from the establishment year. For the purposes of the study, in Microkastro Vojo Kozanis, lavender experimental field was established on November 2017 and the results refer to the experimentation years 2018 and 2019. The effect of four different formulations (bio-stimulants and foliar preparations; control, amalgerol 15,000 cc ha^–1, millerplex 450 cc ha^–1, sugarxpress 12,000 cc ha^–1, in three equal applications) on flower yield, essential oil content and yield were studied in a completely randomized experimental design under five replicates. The bio-stimulants application produced significantly higher flower shoots and essential oil yield comparing with control. The use of millerplex resulted to higher essential oil yield in higher values than the reported in literature, while the use of 'amargerol' produced flowering shoots with stable essential oil content for both experimental years. Therefore, the use of the above mentioned bio-stimulants is suggested to be used from the establishment year and thereafter, while further investigation on essential oil quality should be considered.

摘要

薰衣草是一种芳香药用植物，通常在希腊和地中海盆地种植。本研究的目的是研究使用生物刺激剂是否可以从开花年开始就提高开花枝的产量和精油含量。出于研究目的，于2017年11月在Microkastro Vojo Kozanis实验室建立了薰衣草实验场，结果参考了2018年和2019年的实验年。四种不同配方（生物刺激剂和叶面制剂；对照品，金合欢15,000）的影响cc ha ^–1，millerplex 450 cc ha ^–1，sugarxpress 12,000 cc ha ^–1，在三个相等的应用程序上）对花朵的产量，精油含量和产量进行了完全随机的实验设计，重复了五次。与对照相比，生物刺激剂的施用产生了更高的花枝和精油产量。与文献报道相比，使用Millerplex可获得更高的香精油产量和更高的价值，而在两个实验年中，使用“ amargerol”产生的花梢均具有稳定的香精油含量。因此，建议从建立之年起及其后使用上述生物刺激剂，同时应考虑进一步研究精油质量。
