  • Field experiment was conducted to investigate the effect of vinyl mulch on phosphate availability of soil and fertilizer in 1982. Growth of tobacco was more vigorous at each level of phosphate treatment in vinyl mulched than in bare soil. There was significant culture x Phosphorus treatment interaction for the yields of cured tobacco leaves. These results indicated that vinyl mulch was effective to improve phosphate availability of soil and fertilizer. Increase in soil temperature and maintenance of bulk density suitable for Phosphorus diffusion by vinyl mulch were likely to Play major roles on Phosphate availability, but other unknown factors appeared to be involved.

  • The purposes of this study were to examine effect by Solid Matrix Priming(SMP) ; method far enhanced rapid and uniform seedling emergence in tobacco seeds. The results were as follows. No enhancement of germination rate was by SMP treatment. In KF114 during 9 days treatment and in KB108 during 7 days treatment, germinative energy was highest, and T50 and mean germination time were the shortest. Cells in embryo and hypocotyl were divided and extended during SMP treatment. The contents of fatty acid were increased in SMP treatment. The changes of glucose content were little.

  • To find out the effect of transplanting time on the autonomic characters, yield of cured leaves and content of polyphenols in burley tobacco, three transplanting time were evaluated. The results obtained are as follows. Low temperature which was caused damage earliest stage of tobacco in early transplanting could escape by vinyl mulching and other treatment. 2. The major polyphenols in leaves were chlorogenic acid and rutin, small amount of scopolin and quercetin were also detected. 3. Chlorogenic acid decreased during curing. 4. Polyphenols content was not influenced by transplanting time.
