  • This experiment was conducted to investigate the effects of soil conditioners, such as lime, borax, poultry waste sawdust manure (P.W.S.M) and mixed oil cakes (M.O.C), on the rutin biosynthesis and the yield of buckwheat. The content of phosphorus ($P_2O_5$) in buckwheat plants before flowering was higher at before flowering than that of flowering time at all plots. The content of nitrogen (N), potassium ($K_2O$), calcium (CaO) and magnesium (MgO) was lower at before flowering than those of flowering time at all plots. The contents of rutin in buckwheat plant at flowering time was higher than that at before flowering content of rutin in leaf was higher than that in stem. The contents of rutin in buckwheat plant was the highest at the plot treated with borax (B) compared to other plots. Correlation between rutin and amino acid was positive in buckwheat leaf, while it was negative in buckwheat stem. The yield of buckwheat was 21 percent higher at the plot treated with borax than the plot applied with the other three ingredients.

  • This experiment was conducted to investigate the effects of growth retardant uniconazole on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One'. Reduction in leaf length of both cultivars was proportional to the amount (0-5g) of uniconazole and growth reduction of 'A One' was more remarkable than 'Moon Venus'. The inflorescence length was reduced 18.4% in 'Moon Venus' and 15.3% in 'A One' by 5g treatment of uniconazole. There was no significant difference in flowering time, number of inflorescences and florets and size of lower sepal regardless of uniconazole treatment. It was concluded that uniconazole treatment is effective in reducing the leaf growth of Cymbidium. However, as high concentration (5g) of uniconazole reduced the growth of inflorescence causing low quality, 1g was recommended as useful concentration.

  • In order to provide cool night to strawberry plant with cool air and water, an abandoned cool mine was utilized. It's effects on flower induction and fruit yield in 4 different cultivars were examined. After 70 days of transplanting, flowering frequency was below 65% and 100% in control and treatment of night cooling, respectively and regardless of cultivars. Number of flower buds and flower clusters were higher in treated plants compared with the control. Average time until flowering was much less in treated plants. In terms of yield weight and total yield, 'Suhong' was found to be the best cultivar, averaging 24.2g fruit. Cooling contributed to the 6-7 times of increase in total yield within the frame of harvesting times. The fruit were harvested at 80-97 days after transplanting.
