 หัวเรื่อง:การศึกษาการปรับปรุงพันธุ์ปทุมมา (Curcuma sparganifolia) โดยการใช้รังสีแกมมา ผู้เขียน: Adisorn Krasaechai สื่อสิ่งพิมพ์:pdf AbstractThe studies of Curcuma sparganifolia improvement through irradiation using gamma rays from 40 Gy to inhibit sprouting of the rhizomes were conducted. Various effects of gamma rays on growth and development were observed in 11 parameters. Colour mutation of flowers and bracts were not found except in 1 plant which showed deeper bracts colour. Leaf Chimera was observed but the characters for commercialization were not achieved. |
หัวเรื่อง:ผลของรังสีแกมม่าต่อดอกซ่อนกลิ่นไทย ผู้เขียน:Adisorn Krasaechai สื่อสิ่งพิมพ์:pdf AbstractBulblets of tuberose (Polyanthes tuberosa) were irradiated with gamma rays at 0, 5, 10, 15, 20, 25 and 30 Gy, 7.12 Gy/min dose rate. Dose from 10 Gy affected growth rate in all parameter studied. Dose from 25 Gy totally inbibited growth of bulblets. Leaf chimera was found in the irradiated plants but, colour mutation of flower was not found. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Preliminary Studies on the Response of Chrysanthemum Indicum “Hung Chow” to Photoperiod. ) ผู้เขียน:Adisorn Krasaechai สื่อสิ่งพิมพ์:pdf Abstract Some rooted cuttings of Chrysanthemum indicum ‘Hung Chow’ during the studies of the response to the photoperiod, showed rosette type of growth. Under shortday conditions, time from commencing of the shortday to bud visible stage of the rosette cuttings was 162.5 with the leaf number of 74.3, while those with normal type of growth were 21.5 for the former and 24.4 for the latter. Under continuous longday conditions, both time to reach bud visible stage and leaf number are greater than those in shortdays. Those with rosette type of growth, the time to reach bud visible stage was 266.2 with the leaf number of 92.4, while those with normal type of growth were 246.3 and 81.5 respectively. The cause of the rosette was discussed. |
