Abstract

The purpose of this research is to know whether the aqueous extract of Jatropha (Jatropha curcas L.) leaves have an effect on the growth Mustard green seedling (Brassica juncea L.). This research was conducted at Botanical Laboratory of Biology Department Faculty of Mathematics and Natural Sciences University of Lampung from October to November 2018. This experiments were carried out in a complete randomized design with the main factors being aquaeous extract of Jatropha leaves with 5 level concentration : 0% v / v (control), 5% v / v, 10% v / v, 15% v / v, and 20% v / v and consist of 5 replications. Parameters measured were length of aerial part, fresh weight of aerial part, fresh weight of roots, and relative water content. Homogeneity of variance was determined by Levene test at 5% significant level. The results showed that Jatropha leaf water extract stimulated the aerial part of the seedling of mustard green, the extract concentration of 15% to 20% stimulated the weight of fresh aerial parts and fresh weight of roots and relative moisture content. From the results of the study concluded that the extract of Jatropha leaves affected the seedling growth of mustard green and has the potential as a stimulator for growth of mustard green germination.
