| dc.description.abstract | Research of the Pb effect on the lettuces growth was done in Botanical Garden Department of Biology, Mathematics and Sciences Faculty in Riau University on April-July 2010. The aim of this research was to observe the effect of Pb(NO3)2 on the growth of the lettuces and the contents of lead in lettuces. This research used Completely Randomized Design (CRD) with 5 treatments and 3 replications, namely giving aquades as control, and the treatments nutrient solution of Pb(NO3)2 at concentrations 25, 50, 100 and 200 ppm. After a week of planting of seedling at polibag, nutrient solution of Pb(NO3)2 has given 100 ml once a week. The media was a mixture of top soil, sand, chicken manure and compost with the proportion of 4:1:1:1. Data were analized using ANOVA and test with DMRT at 5%. The observed parameters were plant height, root length, leaf number and fresh weight of the plant. Contents the Pb in soil and lettuces were analyzed. The result of the research showed that giving of Pb(NO3)2 until the highest concentration 200 ppm did not inhibited the growth of the lettuces and the highest Pb concentration was found in the root than in the shoot of lettuces. | en_US |
