Abstract
abstract Bambusa vulgaris and Schizostachyum brachycladum are similar but differ in stem shape, branching type, and the presence of aerial roots . B. vulgaris bamboo has various uses, such as a support in concrete construction, and because it is resistant to river abrasion, while its shoots are used as a vegetable. S. brachycladum , which has a very thin stem pith , is used for cooking grilled sticky rice ( lemang ), so it is often called bamboo lemang . The aim of this study was to compare the anatomical structure of the culms of B. vulgaris and S. brachycladum in Lombok. Two methods were used in the preparation of the samples: the permanent slide method with glycerin jelly closure and the maceration method. Transverse and tangential stem slides were used with double staining, using 0.5% safranin O (50% alcohol) and 1% (1 part Aniline Blue + 4 parts picric acid) in 95% alcohol. Fibre slides were prepared using 50% acetic acid maceration solution and staining 50% peroxide and 0.5% Safranin O (50% alcohol). The results showed that the stems of S. brachycladum cv. Green are characterized by short and long cells, a number of vascular bundles in the pith, and a different periderm structure from B. vulgaris . The greatest anatomical differences in the culms of B. vulgaris var. vulgaris and var. striata lie in the arrangement of the periderm tissue and the number of vascular bundles.
