Abstract

Peppermint (Mentha piperita L.) merupakan salah satu tanaman herbal yang mampu menghasilkan metabolit sekunder yang terdiri dari komponen minyak atsiri. Salah satu metode peningkatan produksi metabolit sekunder yaitu dengan pemberian cekaman. Tujuan penelitian ini yaitu menguji pengaruh konsentrasi polietilen glikol (PEG 6000) terhadap pertumbuhan tanaman peppermint dan struktur trikoma glandular tanaman peppermint. Tahap penelitian meliputi pemindahan tanaman peppermint dari media tanah kepada media hidroponik yang mengandung PEG 6000 pada konsentrasi 0 gr/L (kontrol), 2,5 gr/L dan 7,5 gr/L selama 5 hari, pengambilan data parameter perhitungan densitas dan diameter trikoma glandular abaksial daun, luas daun, berat basah dan kering, pengukuran kandungan klorofil dan karotenoid pada daun. Hasil penelitian menunjukkan bahwa pemberian PEG 6000 dengan konsentrasi 2,5 gr/L dan 7,5 gr/L selama 5 hari tidak memberikan pengaruh yang signifikan terhadap parameter yang diamati, yaitu densitas dan diameter trikoma glandular, luas daun, berat basah dan berat kering, kandungan pigmen klorofil dan karotenoid. Meskipun demikian, terdapat kecenderungan peningkatan diameter trikoma pada perlakuan PEG 2,5 gr/L dibandingkan kontrol. Hasil analisa menggunakan ANOVA one way dan uji lanjut menggunakan Duncan Multiple Range Test apabila terdapat nilai signifikan dengan tingkat kepercayaan 95%
=================================================================
Peppermint (Mentha piperita L.) is one of the herbal plants capable of producing secondary metabolites composed of essential oil components. One method of increasing secondary metabolite production is through stress induction. The objective of this study is to examine the effect of polyethylene glycol (PEG 6000) concentration on the growthof peppermint plants and the structure of glandular trichomes in peppermint plants. The research stages included transferring peppermint plants from soil medium to hydroponic medium containing PEG 6000 at concentrations of 0 g/L (control), 2.5 g/L and 7.5 g/L for 5 days, data collection on parameters including the density and diameter of abaxial glandular trichomes, leaf area, fresh and dry weight, and measurement of chlorophyll and carotenoid content in the leaves. The results of the study showed that the application of PEG 6000 at concentrations of 2.5 g/L and 7.5 g/L for 5 days did not significantly affect the observed parameters, namely density and diameter of glandular trichomes, leaf area, fresh weight and dry weight, and chlorophyll and carotenoid pigment content. However, there was a tendency toward increased trichome diameter in the PEG 2.5 g/L treatment compared to the control. Analysis was conducted using one-way ANOVA and post-hoc tests using Duncan's Multiple Range Test if significant values were found at a 95% confidence level.
