Abstract

The purpose of this research is to know whether the aqueous extract of purple nutsedge (Cyperus rotundus) have an effect on the growth and chlorophyll content of upland rice seedling of Inpago 8 varieties. This research was conducted at Botanical Laboratory of Biology Department Faculty of Mathematics and Natural Sciences University of Lampung from September to October 2017. The experiments were carried out in a complete randomized design with the main factors being aqueous extract of purple nutsedge with 5 level : 0% v / v (control), 5% v / v, 10% v / v, 15% v / v, and 20%v/v. Parameters measured were shoot length, fresh weight, dry weight, relative water content, and total chlorophyll content of rice seedling. Homogeneity of variance was determined by Levene test at 5% significant level. Analysis of variance and Tukey HSD test is done at 5% significant level. The results showed that the concentration of extract correlated quadratic with shoot length where the maximum shoot length was 3.9 cm at 10% extract concentration. Fresh weight and relative water content maximum were 73.21 mg and 76% respectively at concentrations of 14% and 10%. The minimum total chlorophyll content was 0.47 mg / g tissue at a concentration 11%. There was no significant effect on the dry weight of the seedling. From the results of the study it was concluded that the extract of purple nutsedge at concentration below 14% was a growth stimulator, but it was an inhibitor of chlorophyll biosynthesis.
