Abstract

This study aims to determine the correlation between lead (Pb) content in Puring (Codiaeum variegatum) cultivar Croton leaves to the number of stomata and determine the difference number of stomata at the Bundaran Dolog Surabaya, Jl. Gading Ketabang Surabaya, and Kebun Bibit 2 Surabaya. Sampling was carried out in three different places, at Bundaran Dolog Surabaya, Jl. Gading Ketabang Surabaya, and Kebun Bibit 2 Surabaya. For each locations were taken four plants and four leaves were taken for each plant. Testing of lead (Pb) content was carried out by the AAS method. To determine the correlation were carried out using Pearson correlation on SPSS. The result of the calculation show that the correlation value between lead (Pb) content in croton leaves and the number of stomata at Bundaran Dolog Surabaya 0,51, Jl. Gading Ketabang Surabaya 0,50, and Kebun Bibit 2 Surabaya 0,54. Correlation is negative, so the number of stomata will be lower if the lead (Pb) content is higher.
