Device and methodMaterial of plants: tomatoes, 5 varieties: Golden Jubilee, Red Beefsteak, Cal Ace Ace 55 VF, 24 and Homestead.Experiment 1: study on the growth of tomato Experimental design CRD planning processes that are highly repetitive, 10 5. 1.1 seed crop Soak seeds in warm water 4 hours from the cotton sheets, water sprinkling the seeds are distributed around the mat enough and cotton pads come. Cover the seed in water enough to keep mat clear plastic box off cover. 1.2 the spores dare into plastic bags About 3-4 days, the seed in cotton seed that sprouts began to grow leading planted in seed trays, seed cultivation 1 watering hole, 1.2 move the beginning dare into plastic bags When the saplings are age 25-30 days to prepare the material planted in the planting material, black plastic bag use is Earth, ruan. Put a black plastic bag on the ground, almost full ruan bags. Rest the end socks 10 cm water, leave for 2 days before planting. Moving trees, tomato 1/bag The bottom hole with minor drug paradise Triathlon rider came to Cologne. 1 tbsp/bags, watering and fertilizer application measures the height growth after planting 2 weeks 4 days 6 times.Experimental study of histology at two plants of tomato garden. Experimental design CRD planning agencies that process is 5-1 with a total of 8, the second process is the process number of 4, 3, 6, 5, 4 are highly repetitive, repetitive process, 5 3. How to When the tomatoes are ripe unto a red output from store. Weigh the output from them is random. Keep the information the consequences once a week how many tomatoes 3 times as follows: length, width, thickness, amount of the channel contents in tomato.Experimental study on nutrients in 3 tomato results. Experimental design CRD planning process, each process is repeated 5 1 3 results. How to bring the tomatoes separate until the step 1 result in each repeat, and then try to find a percentage breakdown of the soluble quantity. By bringing the cycling more tomatoes with white cloth, some minor water and then remove only the measure adopted by the TSS drops onto the Prism sheets of hand refractometer reading is from 0 degrees to borik-borik, 32 degrees. Using distilled water as a compared (arunothai, 2546) and find out the quantity of vitamin c. Take 2 ml fill volume of tomato juice into a bottle of distilled water, 5 ml tree, fill a volume of 5 ml metaphosphoric acid acetic acid mixed together and then pour the solution 2, Tai tonkap 6-dichlorophenol indophenols until the end point. Record the volume and calculate the quantity of vitamin c. Unit is mg. Per 100 ml by calculated from the formulaVitamin c = x/2Y X 100By Y = volume 2, 6-dichlorophenol indophenols used with examples. X = volume 2, ascorbic acid is used to 6-dichlorophenol indophenols.
