Device and method
materials: tomato 5 plant species such as Jubilee Golden, Red Beefsteak, Ace, Cal VF Homestead 24 and Ace 55
Experiment 1 study early growth of tomato
experiment CRD have 5 karma how each process 10 repeated
1.1 seed seed soaking in warm water, 4 hours. Then the cotton sheet coating damp enough water and scatter seeds around. The cotton sheet and one to cover, water injection, when dry, keep the beans in the plastic box plastic Closed boxes
1.2 the seedling into a plastic bag
.About 3-4 days in cotton seeds begin to sprout. The seed germination and seedling tray hole each 1 seeds. รดน้ water soaked
1.2 move seedlings into a plastic bag
.The brave are about 25-30 days. Prepare the plant material is put into a black plastic bag plant material used is loose, put in a plastic bag black loam almost full bag. Bag left end about 10 cm water soaked left 2 days before planting.1 plant / bag. The second hole with hard mould Trichoderma 1 tablespoons / bag, water soaked and fertilizer measure the growth in height after planting 2 week. Apart 4 days of 6 times
.
Experiment 2 the horticulture tomato experiment is 5
CRD process industry how 1 8, there were repeated. The process 2 were repeated 4, 3 process were 6 repeat, the process 4 were repeated 5,The process 5 were repeated 3
.How, when tomato ripening stage, red harvest and the weigh total output per plant, then randomly collected the tomatoes. A week 1 times of 3 times: length, width, thickness of the meat.Experiment Study 3 nutrients in tomato fruit
experiment CRD have 5 process, each process 3 repeated again? 1 Effect
.How to bring the spinning by 1 tomato separately each repetition. Then divide the experiment percentage of soluble solids, the tomato spin, so two whites take only water, then measure the percentage. TSS.Hand refractometer reading degrees Brix, since 0-32 degrees Brix. Using distilled water as a comparison (blush,2546) and determination of vitamin C, the tomato juice, Volume 2 ml fill in Apple 5 ml distilled water bottle filling and filling metaphosphoric. Acid acetic acid volume 5 ml mixed together and then the titanium dioxide solution, 2.6-dichlorophenol indophenols until the end point, save volume and calculated for the determination of vitamin C is measured in mg per 100 ml By calculating formula of vitamin C
= 2Y / X x 100
by Y = quantity, 2 6 - dichlorophenol indophenols used to sample
X = quantity, 26-dichlorophenol indophenols used with ascorbic acid
