Abstract

The study aims to investigate the way of growth response, the result, and proline accumulation of three varieties kinds of the national best quality of patchouli (Pogostemon Cablin, Beth) under the thread of drought stress. The research is done in plastic house in Reuleut Timu village, Muara Batu subdistrict, Aceh Utara Districk, from June – November 2015. The research is held by using split-plot design by six replications of two factors, namely the provision of water factors (K) at field capacity (FC) as the main plot, K1= provision of water 100% FC, K2 = provision of water 75% FC, K3 = provision of water 50% FC, K4 = provision of water 25% FC. The varieties of patchouli ( V) as sub-plot, V1 = Lhokseumawe (from Lhokseumawe/North Aceh), V2 = Tapaktuan (from Tapaktuan / South Aceh), V3 = Sidikalang (from Sidikalang, North Sumatera). The parameter measured were plant height, number of branches, length of the root, weight of wet plant, leaf area, proline accumulation, and the total amount of chlorophyll. The result showed that the water in different field capacity had a significant effect on plant height, root length, wet weight, and total amount of chlorophyll of leaves and highly significant on accumulation of proline content in leaves of patchouli. The bigger drough stress will reduce vegetatif growth and the total amount of chlorophyll and would incerase the accumulatin of proline in leaves. The best respond vegetative growth patchouli to drought stress obtained in Tapaktuan varieties shown in plant height, number of branches and root length highest compared to the other varieties. Varieties Tapaktuan also accumulation the highest proline as response to the greater drought stress given
