Bentuk Sel Epidermis, Tipe dan Indeks Stomata 5 Genotipe Kedelai pada Tingkat Naungan Berbeda
ABSTRACT: Shape of Epidermal
Cells, Type and Stomata Index of 5 Soybean Genotypes at Different Levels of
Shading. This study aimed to determine the shape of epidermal cells, type of
stomata and the stomatal index of five soybean genotypes at different levels of
shading. Research conducted at the Screen House of Indonesian Legumes and Tuber
Crops Research Institute in March until July 2007. Split plot design with
repeated three times was used in this research. The main plots were four levels
of shading (0%, 25%, 50% and 75%) and subplot is the five soybeangenotypes
(Pangrango, Tanggamus, Wilis, Lokon and IAC-100). Shading is used black screen.
Plants fertilized with the 50 kg Urea + 100 kg SP36 75 + 75 kg KCl / ha.
Fertilizing done atplanting time. The results showed that shade does not change
shape of epidermal cell andstomata types of five soybean genotypes. Differences
in stomatal index was not determinedby interaction of genotypes with levels of
shading, but by the differences in shade and genotype. Shading treatment
increased stomatal index of soybean abaxial leaf surface. HighestSomatal index
of soybean abaxial leaf surface is achieved by IAC 100 and the lowest is
achieved by Wilis. Wilis is a genotype that can be adapted to the shaded
environment, by maintaining leaf area, number of epidermial cells and stomata,
stomatal index, and seed weight.
