Abstract

The efficacy of coriander extract (Coriandrum sativum L.) on germination and growth of soybean (Glycine max) and rice (Oryza sativa L.). The objective of this experiment was to evaluate the effect of coriander extract on germination and maturation. The growth of soybeans and rice and to compare solvent concentrations affecting germination and growth of soybeans and rice. The experiments were performed to extract allilopatic from coriander for a period of 7 days by cultivating soybeans and rice in sealed containers in the tissue culture room, 4th floor, Vachiranusorn Building, light at 16 cm., Dark 8 cm. And temperature control. At 24 ° C, four repeated complete randomized block (RCBD) block trials were planned, using two solvents, distilled water, and hexane at four concentrations 0 (T1 control), 10 (T2), 20 (T3. ) And 30 mg / ml (T4). The results showed that coriander extract was extracted with 7 days of distilled water to promote germination and growth. In soybean concentration, germination and growth were increased with 30 mg / ml concentrations, 98.75% maximum germination, 8.02% root length and 2.38% root length. Hexane inhibits germination and growth of 100% of the total concentrations of the extract by causing the death of soybean seeds. It was shown that hexane inhibited the germination and growth of soybeans better than distilled water, while distilled water improved the germination and growth of soybeans. If the extract concentration is increased, it will also promote the germination and growth of soybeans. From the experiment results, extracts were used in the rice experiment. Allilopatic extracts from coriander extracted using a distilled water solvent at a concentration of 30 mg / mL tested in soybeans were maximized. But when testing rice, the growth of rice was lower compared to that of soybeans.
