 หัวเรื่อง:อิทธิพลของชนิดและอัตราปุ๋ยไนโตรเจนที่มีต่อผลผลิตของหญ้ากินนีที่ปลูกบนชุดดินกำแพงแสนในสภาพไร่นา ผู้เขียน:Prasert Bunpithukkeit สื่อสิ่งพิมพ์:pdf AbstractA field experiment was established to determine the influence of nitrogen sources and nitrogen rates on the dry matter production of Guinea grass grown on Kamphaeng Saen soil series (Typic Haplustalp five silty, mixed). The experiment was conducted at experimental farm of the Department of Soil Science, (Kamphaeng Saen campus), Kasetsart University, Nakorn Pathom. In 1989, a factorial experiment in randomized complete block design of three nitrogen sources, urea (46% N), ammonium sulfate (21% N) and ammonium chloride (25% N) While rates of nitrogen were 0, 25, 50 and 75 kg N/rai with 3 replications. The grass was harvested for analysis every month and these analysis have carried out for six months. The average of dry matter yields and N yields of Guinea grass showed no significant difference from various nitrogen fertilizers. The ammonium sulfate application gave the highest average dry matter of 2,230 kg/rai. On the other hand, the highest N yields was 33.04 kg/rai when applied ammonium chloride. The yields of Guinea grass increased with increasing level of nitrogen fertilizer application. Average dry matter production of Guinea grass obtained from different rate of nitrogen fertilizer were significant difference and at 75 kg N/rai, the highest dry matter yields and N yields were 2,720 and 45.86 kg N/rai, respectively. The recovery of nitrogen was between 38% to 45%. The highest nitrogen recovery was 45% from ammonium chloride, following by urea 43%, While the lowest one was about 38% from ammonium sulfate. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Uranium Absorption Ability of Sunflower,Vetiver and Purple Guinea Grass) ผู้เขียน:ดร.นวลฉวี รุ่งธนเกียรติ, ศาสตราจารย์ , Pimsiri Sudsawad, Narippawat Ngernvijit สื่อสิ่งพิมพ์:pdf AbstractThe ability of sunflower, vetiver and purple guinea grass to absorb uranium from yellowcake solution was compared. Using an image plate technique, beta and gamma rays from uranium daughter nuclides were used to stimulate image plate phosphor to determine the distribution of uranium in plants. The results showed that all three plants could accumulate uranium in their roots better than in shoots, while sunflower showed the best uranium absorption in general. In both solution and sand culture systems, sunflower absorbed uranium better than purple guinea, while vetiver had the least absorption. Moreover, sunflower absorbed higher quantities of uranium as the growing time increased. Although yellowcake, at pH 4, facilitated better uranium absorption than at pH 7, growth was found to be better at pH 7. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Inducing Salt Tolerance in Purple Guinea Grass (Panicum maximum TD58) via Gamma Irradiation and Tissue Culture) ผู้เขียน:นายประดิษฐ์ พงศ์ทองคำ, ศาสตราจารย์เกียรติคุณ , สุมล นิลรัตน์นิศากร, Surin Piyachoknakul, นางอมรา ทองปาน, รองศาสตราจารย์, Jantakarn Aranananth, Krisana Kowitwanich, Sayan Tadsri สื่อสิ่งพิมพ์:pdf AbstractThe seeds of Panicum maximum TD58 were cultured on MS medium supplemented with 15% coconut water, 5 mg/l kinetin and 100 mg/l casein hydrolysate to induce multiple shoots. The gamma irradiated shoots grown in 0–2.0 % NaCl gave 58 clones of purple guinea grass. All clones were transferred to grow in the natural field. Ten clones of grass with good morphological properties were selected and subsequently grown in the salt stress environment at Maha Sarakham province, Northeastern Thailand. Under salt stress condition, seven out of ten selected clones showed salt tolerant trait. However, there was no difference in AFLP fingerprinting patterns found as compared with the controlled non-irradiated guinea grass. The salt tolerance character might be due to the mutation at a certain location or on a specific gene which could not be distinctly detected by the available AFLP primers. |

หัวเรื่อง:ผลของเวลาเก็บเกี่ยวที่มีต่อผลผลิตและคุณภาพของเมล็ดพันธุ์หญ้ากินนี ผู้เขียน:นางสุนันทา จันทกูล, ผู้ช่วยศาสตราจารย์, นายสนั่น จันทร์คำ, ดร.สายัณห์ ทัดศรี, ศาสตราจารย์ , Pranee Khantongchai สื่อสิ่งพิมพ์:pdf AbstractThe experiment was conducted at Kampangsaen Campus Kasetsart University in wet and dry season of 1985 in order to determine the effect of harvesting times on seed yield and quality of quinea grass. The inflorescences were harvested from each plot at 10, 14, 18, 22 and 26 days after panicle emergence. The results showed variation in both yield and quality of seed harvested at different ages and seasons. Maximum seed yield (631 kg/ha) was obtained from panicles harvested in the wet season at 18 days after panicle emergence while the dry season harvest was peaked at day 10(341 kg/ha). Pure seed yield was highest at 26 days harvest in the wet season (266 kg/ha) and was lowest at the 22 days harvest in the dry season (174 kg/ha). However, seed quality was found increased with the increasing age of panicle. |
