 หัวเรื่อง:การวิเคราะห์หาปริมาณ แซนโทฟิล และแคโรตีน ในกลีบดอกดาวเรือง เพื่อให้เป็นพืชสี ผู้เขียน: Sompian Kasemsap, Permsak Suthevaree, Warunee Warunyanond, Amorn Pethsom สื่อสิ่งพิมพ์:pdf AbstractAnalysis of pigments in petals of various marigold cultivars grown at Experimental Plot II, Department of Horticulture, Kasetsart University and at Royal Ang Khang Station revealed that xanthophyll and carotene contents in both fresh and dried petals as determined by AOAC and WRRL methods varied among cultivars and flower color groups. The cultivars with orange flowers especially Toreador was suitable for dye purposes. This cultivar yielded more xanthophyll and carotene contents when grown at Royal Ang Khang Station than at Bangkhen. Suitable cultivars that should be grown for dye at both Bangkhen and Royal Ang Khang Station in order of xanthophyll content are Toreador, Orange Lady, Pumpkin Crush, Apollo, Matador and Red Brocade with the respective xanthophyll contents of 15,249.54, 13,751.34, 13,376.79 13,323.28, 12,918.73 and 11,985.60 ppm. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The Use of Ethephon for Height Control of Marigolds) ผู้เขียน:Sompian Kasemsap,  ดร.พูนพิภพ เกษมทรัพย์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractFour applications of ethephon at the concentration of 250-4,000 ppm were applied weekly as soil drench to potted ‘sovereign’ Marigold. The first application was made suddenly after pinching. The result showed that the plants height was decreased respectively when increased the concentration of ethephon. The size of flowers treated with 2,000 and 4,000 ppm decreased slightly and significant differences from the others and delayed flowering about 3-5 days. At these concentrations induced adventitious root along the stem and branches, also caused wide angle of lower lateral branches. |
หัวเรื่อง:ผลของน้ำตาลทรายและ 8-ไฮดรอกซีควิโนลีนซัลเฟต ต่ออายุปักแจกันของดอกเยอบีราพันธุ์ Lea ผู้เขียน:ดร.สุรวิช วรรณไกรโรจน์, รองศาสตราจารย์ , Padidta Tiprat, Sompian Kasemsap สื่อสิ่งพิมพ์:pdf AbstractA study on the effectiveness of sucrose and 8-hydroxyquinoline sulfate (8-HQS) in holding solution for “Lea” cut gerbera was conducted. The single ingredient of either 3% and 5% sucrose or 100 and 200 ppm was ineffective for vase-life extension when compared with the deionized water. The combination of 200 ppm 8-HQS and either 3% or 5% sucrose delayed the loss of freshness and led to the longest vase-life; however, the Solution with 3% sucrose showed less turbidity. All treatment had no effect on an average water consumption. |
 หัวเรื่อง:การศึกษาต้นทุนและรายได้จากการปลูกมะลิเป็นการค้า ผู้เขียน:Sompian Kasemsap, Tharee Hiranrusme, Boonyoung Sahatevasukont สื่อสิ่งพิมพ์:pdf Abstract Jasmine cultivation in winter, summer and rainy seasons would incur an average cost of about 15,044.10, 17,411.13 and 25,116.19 Baht per rai, average selling price per litre were 57.50, 24.50 and 32.50 Baht respectively. It was found that the yield in summer was 1,321.00 litre per rai raining season and winter season were 1,100.00 and 341.00 litre per rai respectively. In terms of rate of return to investment it was found that the rainy season yields greater revenue than those of the other seasons. A note can be made from the study that the highest yields are from summer season. In economic terms, the rate of return on investment in summer, winter and rainy season were 31.05, 20.99 and 22.92% respectively with payback period in 16 months. |
หัวเรื่อง:การศึกษาต้นทุนและรายได้จากการปลูกกุหลาบตัดดอก ผู้เขียน:Sompian Kasemsap, Nantaporn Lertbutr, Sirinan Krisuchat สื่อสิ่งพิมพ์:pdf Abstract The study on costs and return on rose production of 4 popular cultivars; namely, Christian Dior, Eiffel Tower, Swartmore and Yankee Doodle, found that the cost of Eiffel Tower and Swartmore was lowest, which was 0.22 Baht / flower, while that of Christian Dior wad highest, (0.35 Baht/flower). The Net income from Yankee Doodle was highest, but that of the Christian Dior was lowest. Pay back period of production investment was 1 year for Eiffel Tower, Swartmore and YanKee Doodle, and 2 years for Christian Dior. The Net present Value (NPV) was positive for all cultivars investment. |

From the analysis on the rate of return, a summary can be made that in hot, rainy and cold seasons, the ratio of profit margin to total revenue were 0.63, 0.62 and 0.15, respectively. The ratio of profit margin to total production cost were 172.30, 163.25 and 17.80 percent, respectively.
