2. preparation of concentrated extract Leading the extract step 1 prepare the concentration level is 0.5 1.0 1.5.And 2.0 mg/ml3. the testing of plant extracts, per the germination and growth of green beans, black. Cultivating beans, green, blackThen, extract from herbs of 6 types by the prepared concentrations from step 2 green beans by sanction dosing plant extracts in each concentration, volume has 5 mg and then watering in a Petri dish and placed in the control cabinet temperatures of 25° C.For a period of 4-7 day plan Completely Randomized Design trials are due in four duplicates when planting. Seed germination data recording. Length of dry weight, root length and amount of seedlings.

2. Preparation of the concentrated extract. The extract from step one prepared at a concentration of four levels: 0.5, 1.0, 1.5
and 2.0 mg / ml
3. testing of plant extracts on the germination and growth of black beans. The seeds, black beans
, the extracts from medicinal plants, six types of concentrations prepared from step 2 to the green beans. By measuring the plant extract in a concentration of 5 mg, then pouring it in Petri dishes. And then placed in a controlled temperature 25 C °
for a period of 4-7 days Randomized Completely Randomized Design with four replications at maturity in the nursery. Logging germination, root length, total length and dry weight of seedlings.

2. Preparation of concentration of the extract extract from step 1 prepared at concentrations 4 levels is 0.5 1.0 1.5.And the 2.0 mg / ml3. Testing plant extracts to seed germination and seedling growth of mung beans, black. The cultivation of green beans black.Then extracts from medicinal plants 6 type. According to the concentration is prepared from step 2 to green beans. By the measure of plant extract in each concentration to an amount 5 mg and thread in the culture dish, and then placed in ้ควบคุม temperature 25 C °.For a period of 4-7 day experiment Completely Randomized Design have 4 repeated at maturity in growing, record information and germination. Shoot length, root length and dry weight of seedling
