Description
Summary:Abstract The aims of this study to determine the growth and leaf chlorophyll content in black rice ( Oryza sativa L. Indica) which were induced by gamma rays as responses to the drought stress conditions. This study was carried out on July–November 2020, at the experimental field (screenhouse), Medicinae Street, UNS Perum, Jati Village, Jaten District, Karanganyar Regency. Meanwhile, the chlorophyll content test was carried out at Plant Tissue Culture and Biotechnology Laboratory, Faculty of Agriculture, Universitas Sebelas Maret. The study was a field trial research design without replication. The research treatments were 24 genotypes as follows: 10 genotypes of 100 gray gamma-ray irradiation with 2 control genotypes; and 10 genotypes of 200 gray gamma-irradiation with 2 control genotypes. The results showed that the plant height was lower in plants with irradiation compared to the Control-01 plant. The crown-root ratio showed irradiated plants had higher average results than control plants. The leaf chlorophyll of 100 gray irradiated plants showed higher results than control; while 200 gray irradiated plants showed similar results.
