Stomatal Number and Size of Dicotyledon Plants

Abstract

The stomatal number and size influence transpiration, a process of water loss in the plant that cools its environmental temperature. Some dicotyledon plants function as shading plants, especially in the urban area. However stomatal number and size of some plants are not known. This study aimed to know the stomatal number and size in dicotyledon shading plants. The method used factorial completely randomized design (CRD) with the main factors of six dicotyledon plants and plant part of the lowest branch. Whilst the combinations were between the two. The stomatal number and size were sampled using a replica method from these treatments and observed under 10x10 and 10x40 magnification, subsequently. The stomatal number were counted used hand counter and size were measured using a calibrated micrometer. Data were analyzed using SAS with a model of factorial CRD. Both main factors were significant whereas the combinations were not. for stomatal number and size. The highest stomatal number and the largest stomatal size occurred in Syzygium oleana R.Br and Aerva sanguinolenta Bl, subsequently. The Syszygium has the highest number but the smallest size of stomata whereas Aerva sanguinolenta Bl has the other around. The more the leaves developed the smaller number but the bigger size of stomata.
