 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Gamma-rays Induced Morphological Changes in Chrysanthemum. (Chrysanthemum morifolium)) ผู้เขียน: นางสิรนุช ลามศรีจันทร์, ศาสตราจารย์ , ดร.พีรนุช จอมพุก, รองศาสตราจารย์ , นางอรุณี วงศ์ปิยะสถิตย์, ศาสตราจารย์,  Surin Deeseepan, Prapanpongse Kwanthammachart สื่อสิ่งพิมพ์:pdf AbstractThe purple color clone of spray type chrysanthemum available as pot plant in the market was used to study the effect of gamma radiation on in vitro culture of chrysanthemum (Chrysanthemum morifolium). Ray-florets were cultured on the MS medium containing 10 mg/l BA. Multiple shoots produced were irradiated with gamma rays at 0, 10, 30, 50, 70, 90 and 110 Gy. Subculturing was carried out three times from M1V1 to M1V4 after which M1V4 shoots were rooted and transplanted to the greenhouse. M1V4 shoots irradiated at 50 Gy and over died within 25-30 days. LD50 for this purple clone of chrysanthemum was 14 Gy. Only the controls and treated plants at 10 Gy were able to survive and gave rise to the full grown plants. After transplanting into the greenhouse for 60 days, control plants and treated ones were found to be different in four traits which were average height, average number of leaves, average number of nodes and % flowering. Plants were trimmed twice at three month intervals and allowed to produce flowers. Changes in flower characters were found in both controls and treated plants. However, the treated plants had much more variation than the controls and new flower color (yellow tinge) was only obtained from the treated ones. |

หัวเรื่อง:ผลของรังสีแกมมาต่อการเพาะเลี้ยงใบเลี้ยงของถั่วเขียว ผู้เขียน:นางสิรนุช ลามศรีจันทร์, ศาสตราจารย์, นางอรุณี วงศ์ปิยะสถิตย์, ศาสตราจารย์, นายสุมินทร์ สมุทคุปต์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractMultiple shoots were obtained from cotyledons of 7 mungbean cultivars cultured on B5 supplemented with 2, 4, 6 and 8 mg/l BA. Each variety responsed to BA differently. The medium containing 5 mg/l BA was the best for multiple shoot induction. Cotyledon from 3 day-old-seeding gave the highest percentage of shoot multiplication (88.00%) within 18 days. The best medium for root induction was MS medium supplemented with 1 g/l KNO3 and 0.203 mg/l IBA. Seeds of 3 mungbean cultivars were treated with gamma radiation at 200, 400, 600 and 800 Gy and cotyledons were cultured on the medium B5 containing 4 mg/l BA to produce multiple shoots. Shoot and root formations were affected by radiation dose. At 800 Gy, shoot formation was completely inhibited. Rootings were accomplished at radiation dose as high as 400 Gy. |
