The purpose of this research was to develop bagasse packaging antagonizing fungi with turmeric extract for Green Cos Lettuce cultivation. The bagasse package would incorporated with fungistatic turmeric extract instead of using chemicals at concentrations 0 5000 10000 15000 and 20000 ppm. The packaging characteristics efficiency of turmeric extract and the growth of Green Cos Lettuce determined into the percentage of germination height measurement fungi contamination characteristic were tested under the presence and absent antifungal bagasse The plant seedling spreading onto the surface of the packaging with turmeric extracts could be excelled for -their growth with the induction of germination rate of 92-97 percentages. Turmeric extracts at concentrations of 15000 and 20000 ppm had also expel the emergence of Penicillum sp. inhibit Rhizopus sp. and slow down Colletotrichum sp. Moreover the turmeric extract caused packaging decaying by itself slowly possibly helping in common airborne mold prevention. This green safe material showed the respectably effective for Green Cos Lettuce seedling especially for the fungal pathogen contamination during implantations. This research based on using natural extracts and natural fibers from agricultural waste is thus being ecofriendly nonchemical application of packaging product with easily digested for decent consumers who love their health and care environment.

According to the growing and highly competing of textile and apparel industry in Thailand producers has to adopt of new technology to invent new products. Antimicrobial apparel such as baby clothes socks and underwear are innovative product that has antibacterial fiber. However perception and use of such products are not very widespread so I am interested in studying the factors that affect to the buying antimicrobial apparel behaviour of the consumers living in Bangkok metropolitan by following concept of Rogers Everett (1976). This study was done by quantitative methodology with close-ended questionnaires gathering 384 sampling from consumer living in Bangkok who have bought antimicrobial apparels. Data were analysed using descriptive statistics such as frequency percentage mean standard deviation hypothesis testing was by multiple regression techniques. Independent variables are consumer characteristics innovative factors sociological and communication factor. Dependents variables are buying behavior in antimicrobial apparel of consumer under seasons price times place and frequency of buying with confidence interval of 95 percent. The results were that the buying majority were female mostly employed in private company aged between 32–38 years old with bachelor’s degrees and monthly income 20001-30000 baht. Most of buyers referred to antimicrobial apparels as they can buy as frequently as any times for all year round. Most buyers bought from department stores 3-4 times in every 3 months with the spending less than 1000 baht each time. When proving personal factors affecting consumers buying behaviour it found that consumers with different gender age and occupation have a statistically significant effect on the frequency of buying behaviour at .05 level and consumers with different incomes have have a statistically significant effect on place and frequency of buying behaviour at .05. The study has resulted in differences in purchasing behaviour such products.The buying behavior of antimicrobial apparel of consumer in Bangkok metropolitan has related to innovative factor in very low range and sociological factor in low range. Model of this relationship are Y= 0.980 + 0.274 (X1) + 0.429(X2 X1 is innovative factor X2 while is sociological factor and Y is buying behavior in antimicrobial apparel of consumer in Bangkok metropolitan. All hyprothesis testings are under statistical confident interval level of 95 percent
การใช้ประโยชน์เชื้อราทางด้านการฟื้นฟูสภาพแวดล้อมทางชีวภาพ
เชื้อราเป็นสิ่งมีชีวิตที่มีบทบาทสำคัญในฐานะผู้ย่อยสลายของระบบนิเวศ มีการดำรงชีวิตได้หลากหลาย ทั้งอยู่เป็นอิสระ ดำรงชีวิตแบบปรสิต และราเอนโดไฟต์ เชื้อราส่วนใหญ่จะมีการดำรงชีวิตแบบการย่อยสลาย และดูดซึมสารอาหารจากซากของสิ่งมีชีวิตที่ตายแล้ว จากการดำรงชีวิตที่หลากหลายของเชื้อรา ทำให้มีการนำ เชื้อราไปใช้ประโยชน์ได้มากมาย ทั้งทางด้านอุตสาหกรรม เกษตรกรรม การแพทย์ และสิ่งแวดล้อม ทั้งนี้ ทางด้าน การฟื้นฟูสิ่งแวดล้อมทางชีวภาพ พบว่า เชื้อราสามารถกำจัดสารพิษออกจากสิ่งแวดล้อมได้หลายชนิดทั้ง สารประกอบโพลีไซคลิก อะโรมาติกไฮโดรคาร์บอน สารกำจัดศัตรูพืชกลุ่มออร์กาโนคลอรีน สีย้อม และโลหะหนัก กลไกที่เชื้อราใช้ในการบำบัดมีทั้งการดูดซับไว้กับโครงสร้างของผนังเซลล์และการย่อยสลายด้วยเอนไซม์ที่หลั่ง ออกมานอกเซลล์
Evaluation technique for northern corn leaf blight resistance and identification of resistance genes position in maize with dna markers
This study aims to develop a new evaluation technique for Northern Corn Leaf Blight (NCLB) resistance in maize under greenhouse condition. Ki48/Ki47 F2 (160 lines) and 2 commercial verities (Hi-Brix3 and Insee2) were evaluated. For this technique 10-14 day old seedlings (4-5 leaves) were sprayed with ACIL1 spore suspension (104spores/ml.) for infection. The results of this technique correlated with the results from the common technique under field condition which used 21-25 days old seedlings (6-7 leaves) (correlation value = 0.658). This evaluation technique was used to assist in QTL mapping of NCLB resistance. Population of Ki48/Ki47 F2 (160 lines) were analyzed for QTL mapping by using Simple Sequence Repeats (SSR) markers. It was found that major parental polymorphism located on chromosome 5 and chromosome 8. When Single QTL analysis was performed SSR marker UMC1365 could clearly indentified qualitative trait loci on chromosome 5 and SSR markers UMC1095 UMC1268 and UMC2356 could clearly indentified qualitative trait loci on chromosome 8.
