 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Seed Composition and Physiological Changes in Thai Peanut cv. Kaset 1 and Tainan 9 during Maturation) ผู้เขียน:นางสาวปาริชาติ พรมโชติ, ผู้ช่วยศาสตราจารย์, จวงจันทร์ ดวงพัตรา, ดร.วันชัย จันทร์ประเสริฐ, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractPhysiological changes and chemical compositions in peanut seed during maturation were investigated in two Thai cultivars: large-seeded Kaset 1 and medium-seeded Tainan 9. Nine maturity stages (5-13) of both cultivars designated by the Physiological Maturity Index (PMI) method were studied to determine its appropriateness for maturity classification. Physiological maturity (PM) of Kaset 1 was evident at stage 10 with a seed moisture content of 36.37% while in Tainan 9 PM was attained at stage 11 with a seed moisture content of 35.48%. Peanut seed size, seed weight and the seed/ hull dry-weight ratio increased as the seed matured and reached a maximum at PM, while seed moisture content declined and was stable from PM onwards. In Kaset 1, seed dormancy was found at stage 5 and was maximized (90%) at stage 9, while in Tainan 9, seed dormancy was found marginally at stage 12 (4.0%) and 13 (1.3%). During seed maturation of both cultivars, oil accumulation increased rapidly while carbohydrate content declined. Protein content did not change notceably during seed development. The oleic acid and the O/L (oleic/linoleic acid) ratio also increased while palmitic, linoleic, ecosenoic and behenic acid contents decreased. At maturity (stage 13), oil, carbohydrate and protein contents in Kaset 1 seed were 55.9, 21.7 and 20.1%, respectively and in Tainan 9 seed were 54.8, 21.5 and 21.2%, respectively. Regardless of the difference in seed size, the oil content of Kaset 1 and Tainan 9 peanut seeds was marginally different, while the O/L ratio of Kaset 1 seed was higher than that of Tainan 9 seed. It can be concluded that the PMI method was appropriate for classifying the maturation of peanut fruit and predicting the harvest date for Thai peanut cultivars. |

หัวเรื่อง:ลักษณะทางกายวิภาคและการพัฒนาของเยื่อหุ้มเมล็ดถั่วลิสงพันธุ์ขอนแก่น 60-3 เกษตร 1 และไทนาน 9 ผู้เขียน:Wasu Amaritsut, จวงจันทร์ ดวงพัตรา, นางเทียมใจ คมกฤส, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA study on anatomical structure of wrinkleness peanut seed coat in the two large-seeded peanut varieties, Khon Kaen 60-3 and Kaset 1 and one small-seeded variety, Tainan 9 revealed that the two large-seeded varieties were higher in percentages of wrinkled seed than Tainan 9. Seed coat thickness and seed moisture content decreased as the peanut seeds approached maturity. Wrinkled seed coats were thinner than the non-wrinkled seed coats. Wrinkleness of peanut seed coat was found to have been caused by the curvature of the seed coat surface along the vascular bundles while the non-wrinkled one had smooth seed coat surface. The curvature of the seed coat resulted in the more external surface area of the wrinkled seed. |
