The cuttings of shoot positions (Apical， sub-apical) of Elaeagnus macrophylla Thunb. and Ficus formosana Maxim.that were taken cuttings and IBA treatment in March， June and September. The result showed that the rooting rates of Ficus formosana Maxim. were easier than Elaeagnus macrophylla Thunb.The rooting rates of Apical shoot portions were easier。than sub-apical shoots of regardless of cutting collection season，cutting position and IBA concentrations， The rooting rates of Elaeagnus macrophylla Thunb. were high in September. But the higher rooting rates of Ficus formosana Maxim. need more time.。In germination test of Taiwan goldenrain tree and Light sacrificial tree seeds， the results of germination rates demonstrated that there was no significant difference between seeds accepted water soaking for one day and those with no soaking treatment whether seeding in soil or in peat moss mix. The averaged plant height of Taiwan goldenrain tree seedlings which germinated in 128-cell plug with peatmoss mix was significantly。higher than the result with soil medium. The performance of Taiwan goldenrain tree seedlings grown in 24-cell plug with peat moss mix was better than those with soil medium. It was also the same in the result of seedlings grown in 4.5-inch plastic bags. After transplanting to 6-inch pots from 4.5-inch pots or 24-cell plug ， the performance of plant。height， leaf number， stem diameter， the number of roots longer than 10 cm and root weight of plants grown in peat moss mix was better than those in soil medium. In the stage of 128-cell plug seedlings， the leaf number of Light sacrificial tree seedlings grown in soil medium was more than those in peat moss mix. The averaged plant heights of both treatments were not significantly different. In the stage of 24-cell plug or 4.5-inch plastic bag seedlings， the performance of seedlings grown in soil medium was。better than those in peat moss mix.。Two intergenerational Kennebec varieties of potato subculture Plant growth and tuber production are not significantly difference. But four intergenerational subculture of tuber production are significantly difference by the environmental impact of difference planting time. 19 pot chrysanthemum varieties collected in this study were tested for virus infection percentage . The results indicated that CAB virus， 25% infection percentage， was the mainly one infected in chrysanthemum plants， and virus-free plants were isolated and raised for stock plants.The leaf size and internode length were smaller in high temperature treatment (38/25℃) than in control treatment (25/18℃)， and the scion。quality was also reduced in high temperature condition. In the fertilizer treatment， Peters 30-10-10 treatment got more flowers than other treatments， however， 20-20-20 and 15-10-30 treatment had more cuttings.。
