中文摘要 | 十三個品種插穗的發根率除「藍色月亮」與「超級迪斯可」祇達40%外,其餘品種皆可達90%以上。而在腋芽的萌發率,「藍色月亮」與「超級迪斯可」萌發率最低,在10%以下;而「阿爾什米爾的黃金」和「嘉卡蘭達」同為70%,其餘品種都能順利萌發。「沙蔓莎」插穗之發根率,以不具小葉者之發根率20%最差,而具1∼5小葉之插穗發根率則皆可達80%以上。「薄粉」不帶葉片之插穗完全不能成活,帶一片小葉者成活率僅25%,帶2或3片小葉之插穗成活率分別為45%及60%。而有帶4片或5片小葉之插穗,其發根率皆可達100%。「沙蔓莎」和「薄粉」在4、7以10月間扦插,其成活率為90∼100%;而在1月分扦插兩品種插穗的成活率則分別為65%或35%。兩品種在1、4、7以及10月扦插時插穗發根所需天數,分別為45∼65天、36天、17∼18天、或19天。兩品種在7、10月所繁殖的插穗,其腋芽之萌芽率,所形成新梢之鮮重與長度也顯著的優於在1月或4月扦插者。在1994年3月29日上午9時至下午3時,測量葉片光合作用率,發現「沙蔓莎」和「薄粉」兩品種之淨光合率高於「藍色月亮」與「超級迪斯可」兩品種。 又「沙蔓莎」和「薄粉」品種葉片中之磷(P)、鉀(K)、鈣(Ca)、鎂(Mg)、鐵(Fe)、錳(Mn)等元素的含量比以「超級狄斯可」和「藍色月亮」品種含量高。 |
英文摘要 | Among 13 cultivars of Rosa hybrida, the rooting rate of 'Blue Moon' and 'Super Disco' was 40% only, but that of the others was above 90%. The sprouting rate of lateral buds on 'Blue Moon' or 'Super Disco' cuttings was below 10%, that on 'Alsmeer Gold' or 'Jacaranda' was 70%, and that on the other cultivar's cuttings was 100%. only 20% of 'Samantha' cuttings without leaflet rooted while 80% of cuttings with 1 leaflets rooted. 'Pitica' cuttings without leaflet did not root. The rooting rate of 'Pitica' cuttongs with 1、2∼3、or 4∼5 leaflets was 25、45∼60 or 100%, respectively. When 'Samantha' or 'Pitica' cuttings were propagated in April、July and October, the 90∼100% of cuttings were survival. However, when 'Samantha' or 'Pitica' cuttings were propagated in January, the survival rate of cuttings was 65 or 35% respectively. In addition, the days from cutting to rooting for 'Samantha' and 'Pitica' cuttings propagated in January、April、July or October were 45∼46、36、17-18 or 19 days, respectively. Furthemore, on the sprouting rate and fresh weight of lateral shoots, cuttings propagated in July and October were higher than those propagated in January and April. On March 29, 1993, from AM 9:00 to PM:300, the net photosynthesis of 'Samantha' and 'Pitica' were higher than those of 'Blue Moon' and 'Super Disco'. Moreover, the inorganic elements of P、Ca、Mg、 Fe、and Mn were also higher than those in 'Blue Moon' and 'Super Disco'. |
