The purpose of this research was to study the white resist printing with colour resistant material from flour of wild taro (Colocasia Esculenta (L.) Schott) and using reactive pigment and natural dyes as dyestuffs. Five formulas of printing pastes were applied to light cotton thick cotton and silk fabrics by the use three techniques nauely Silk screen (White resist and colour resist methods)stencil and batik. The optimal ratio of colour resistant materials from flour of wild taro were compose of 20 grams flour of wild taro 32-36 ml. water 30-34 ml. sodium chloride 10-13 ml. calcium hydroxide and 1-4% vegetable oil. The viscosities of printing paste from five recipes were shown in the rage between 559.9-671.9 Centipoise. All five recipes can resist dyestuffs and also easy to remove the flour of wild taro. The pattern at resist printing area of fabrics shows sharpness and whiteness. The colour fastness to washing water and perspiration on cotton and silk fabric results were ranging between poor to fair level when using reactive and natural dyes as dyestuff. However the fastness property of pigment dye shows medium to good level. The colour fastness to rubbing is shown to be in range of 4 to 4-5 for all recipes. The ratings of colour fastness to light in terms of colour change are fair to good (4 to >6).

The objectives of this study were to dry Chaploo Leaves at 3 levels: 50 60 and 70C for 3 hours. It was found difference in the moisture values aw and color significantly (p<0.05). 60C is the best value. Then based on 3 formulas of Cereal Bar mixed with Chaploo leaves sensory evaluation in terms of color flavor taste texture and overall acceptable were conducted. Scores of nine levels (9-Point Hedonic Scale) was used for taste test. Factorials Randomized complete Block Design (RCBD) compared the differences of the measures Duncans New Multi Rank Test (DMRT) found that the scores for flavor taste texture and overall 3

The purposes of this research were to study the pattern and the basic need of indigo woven groups in study areas and to design develop the textile products from indigo fabrics to compare the pattern of materials production process textile products and transferred cloth product technology from them. The instruments used were interview comment evaluation an evaluation and training evaluation. The sample groups were 100 interested persons and 20 trainees from Ban Tam Toa Tumbon Samakipattana of Arkat-amnuay District in Sakonnakorn. The Statistics used were percent mean and standard deviation. The results revealed that the two study areas were Ban Bin weavers group of Long district in Phrae and Ban Tam Toa of Arkat-amnuay district in Sakonnakorn. The former groups produced indigo fabrics and varieties products such as garments sarongs scarves and shawls but the patterns were more modern. The later groups produced only indigo fabrics that were not processing into other products except the shawls and the scarves. They wanted to produce the varieties products from indigo fabrics. The design and the development of textile product patterns from them which were leaded to produce the garments from two groups of five patterns. The comment evaluations were the ninth patterns were the most suitable garments include the decoration; pattern and design were an average of 4.65. The comparison patterns materials and textile product process from indigo fabrics found that the former groups produced the fabrics for sarong. They used Chok weaved techniques and varieties colored threads for design which were beautiful and high cost. Another made scarves shawls bags garments materials and indigo plant products indigo water and dye. The patterns of the later groups were different from the former groups which most of them were produced into sarong or sewn to the other products. They were used tied dye processes that were the same color materials and processes as the former groups and they work every day. The assessment of transferred technology the trainees were the later groups that needed to make money. The results indicated that the female trainees were elder 40 years who were weavers elementary education and their income less than 5000 baht. Before training they had known indigo fabric design in very low level. The sewing and the design were low level. After training they had known more three parts and can apply their knowledge to high level. The most of trainees require to next training time.

The objective of this study were to use of RAPD technique for identification of Krachai ecotype in Thailand. DNA from 36 sample of Krachai that collected from every part of Thailand are amplified by 10 primer and relation analysis by UPMGA. This study was conducted at Faculty of Agriculture at Bangpra Sriracha Chonburi. The results showed every primer can made different pattern. After comparison of RAPD pattern from each sample can divide into 2 groups. However every sample is closely genetic relation likes it came from same original.
