 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of branch girdling on total nonstructural carbohydrate content in relation to flowering of two lychee (Litchi chinensis Sonn.) cultivars) ผู้เขียน: Adulsak Koo-Duang, ดร.สุรนันต์ สุภัทรพันธุ์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractStudies on girdling of two lychee cultivars, Hong-Huay and O-Hia in Chiang Rai province during August to December 1982 showed that girdling did not increase percent flowering in the Hong-Huay lychee. In O-Hia cultivar, branch girdling during September to December resulted in an increase in percent of flowering with the maximal flowering percentage obtained when the branches were girdled branches were girdled in October. Total nonstructural carbohydrate (TNC) contents in the terminal shoots of the girdled branches tend to be higher than those of the ungridled ones. From November to June no callus was produced to heal the girdled branches. Callus proliferation in O-Hia caltivar was slower than that months after girdling, and more severe abscission was evident in the O-Hia Cultivar and this was particularly true for the branches girdled in August and September. |
 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Seed Quality on Field Emergence and Seedling Performance of Rubber (Hevea brasiliensis)) ผู้เขียน: Vichai Wongvarodom, Wipharat Duang-iat, Wullop Santipracha, Sayan Sdoodee สื่อสิ่งพิมพ์:pdf AbstractThe effect of seed quality on the emergence and seedling growth performance of rubber (Hevea brasiliensis) was studied. Seven seed samples of various initial quality levels of the RRIM 600 clone were collected from various rubber plantations in Nakhon Si Thammarat, Phatthalung and Songkhla provinces, southern Thailand in 2012 and 2013. The seeds were tested for quality and filed sown to investigate the emergence and growth potential of seedlings using the seedling stem diameter, seedling height and leaf number at 6 mth after germination. The results showed that rubber seeds with germination of 85.50% gave a field emergence of 60.50%, whereas the lower quality seeds (50.50–72.50% germination) had field emergence levels of only 27.00–40.00%. The high quality seeds provided the best growth potential under field conditions based on the seedling stem diameter, seedling height and leaf number at 6 mth after planting with values of 1.17 cm, 118.90 cm and 13.10 leaves, respectively. A comparison among the different quality seeds revealed significant reductions in the performance of seedling characteristics such as seedling stem diameter, seedling height and leaf number, respectively. Therefore, high quality seeds with over 85% germination were recommended for rootstock production and to ensure high seedling performance under field conditions. However, using lower 70% germination rubber seeds resulted in a lower plant population by 20–30% and slower growth than from the high quality seeds. |

 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Physiological Quality and Desiccation Sensitivity of Rubber (Hevea brasiliensis) Seeds during Fruit Maturation) ผู้เขียน: Wipharat Duang-iat, Vichai Wongvarodom, Wullop Santipracha, Sayan Sdoodee สื่อสิ่งพิมพ์:pdf AbstractThe physiological quality and desiccation of rubber seeds were investigated during development. Fruits of rubber clone RRIM 600 at different stages of development were collected from a plantation in Nakhon Sri Thammarat province, southern Thailand, during July–August 2012. Seeds of deep green fruit, yellowish-green fruit, brown fruit and from the naturally shedding stage were tested for their weight, moisture content, germination, mean germination time, seedling shoot height, seedling shoot dry weight, electrical conductivity and desiccation tolerance during dry storage. Rubber seeds with high germination ranging from 86.67 to 95.00% were obtained from the yellowish-green fruit, brown fruit and naturally shedding stages. However, the seeds reached physiological maturity at the brown fruit stage with values for seed dry weight, moisture content and germination of 2.93 g per seed, 34.54% and 95.00%, respectively. At the shedding stage, the seeds had a moisture content and a high germination of 22.17% and 91.66%, respectively. The critical moisture content of the seeds was 15% and at this level, they were very short lived (3–7 d in dry conditions). The seeds with a moisture content of about 15% and from 11 to 12% had germination of 58.33–63.34% and 1.67–8.34%, respectively. Therefore, the early collection of the shed seed is recommended to ensure high quality seed is obtained. Such information may be helpful for improving the seed collection or transport procedures and ensuring high seed performance in the seedbed for successful rootstock production. |
