 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:ไม่มีชื่อไทย (ชื่ออังกฤษ : Harvest Stages and Umbel Order Contribution on Eryngo (Eryngium foetidum L.) Seed Yield and Quality) ผู้เขียน:บุญส่ง เอกพงษ์, นางสุเทวี ศุขปราการ, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractHarvest stages and umbel order contribution were studied from October 2003 to August 2004 to determine the optimum harvest time for eryngo seed production. Maximum seed yield of eryngo accession EF007 was obtained from the seventh (H7) and the eighth (H8) harvest stages with an average of 16.5 gm/m2 when seed color was brownish black with 90% germination. The greatest contribution to seed yield was mainly from the seventh umbel order. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Seed Physiological Maturity in Dill (Anethum graveolens L.)) ผู้เขียน:บุญส่ง เอกพงษ์, นางสุเทวี ศุขปราการ, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractSeed physiological maturity was studied to determine the optimum harvest time for dill seed production at the Faculty of Agriculture, Ubon Ratchathani University during October 2005 to March 2006. Seed reached physiological maturity at 35 days after anthesis with germination of 37.5%. At this stage seed moisture content was too high to harvest and germination percentage was low. The optimum time to commence harvesting should be after seed physiological maturity (45-70 days after anthesis) but before seed shedding. At these stages, seed color was dark brown with 9-12% seed moisture content. The highest seed germination (68.5%) was at 70 days after anthesis while seed started to shed. |
