Correlation of lead (Pb) content towards the number of stomata on the plant

This research is an observational study that aims to determine the characteristics of stomata in the leaves of Dracaena marginata tricolor. This research is descriptive analysis. Sampling was carried out at three locations which had different levels of motor vehicle density, the location at Bundaran Dolog, Jl.Gading Ketabang and Kebun Bibit 2.The calculation of the average lead level in the Dracaena marginata tricolor leaf from the highest was obtained at the Bundaran Dolog Surabaya 2.01 µg / g. Calculation of the average lead level atDracaena margata tricolor leaf of Jl. Gading Ketabang was obtained at 1.06 µg / g and at Kebun Bibit 2 Surabaya obtained an average lead level in the leaves of Dracaena marginata tricolor of 0.82 µg / g. The highest calculation of the number of leaf stomata at the Bundaran Dolog Surabaya of 21. At the location of Jl. Gading Ketabang obtained an average number of stomata of 18 and at the location Kebun Bibit 2 Surabaya the results of the calculation of the average number of stomata were 16
