 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Seed Development and Maturation of Eryngo (Eryngium foetidum L.)) ผู้เขียน: บุญส่ง เอกพงษ์,  นางสุเทวี ศุขปราการ, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractFlowering pattern and seed development were studied in two eryngo accessions (EF006 and EF007) to determine the optimum time of harvest for seed production. Flowering peak was 117 days after transplanting (35.6 umbel heads) and 121 days after transplanting (38.7 umbel heads) in EF006 and EF007 accessions, respectively. Seed in both accessions reached their physiological maturity 40 days after anthesis, with 93.75-95.75% germination when the seed head had just begun to turn brownish black in color. Shattering, however, commenced 65 days after anthesis. |
หัวเรื่อง:ปริมาณ GA และ ABA ระหว่างการพัฒนาและการสุกแก่ของเมล็ดแตงกวา ผู้เขียน:ดร.ชวนพิศ อรุณรังสิกุล , Sutavee Sukprakarn, Shoji Shigenaga, Siriporn Chumsangchoteakul สื่อสิ่งพิมพ์:pdf AbstractThe physiological changes of Jed Bai and Puang cucumber seed were studied in rainy season during May August, 1991. Sed of both varieties reached its physiological maturity at 40 days after anthesis. The highest germination percentages of Jed Bai and Puang were obtained at 30 days and 25 days after anthesis, respectively while maximum viability was about 35 days after anthesis. Endogenous GA found in both varieties were GA1, GA3, GA4, GA7, GA19, GA20, GA24, and GA25. The highest total GA and ABA were obtained at 20 days after anthesis in both varieties but Jed Bai was higher in GA while Puang was higher in ABA than Jed Bai. First highest amount of ABA level was at 20 days after anthesis, the gradually decreased and peaked up again at 35 days after anthesis. |
