Abstract
不同品種落花生生長期間其根瘤固氮活性有顯著之差異，春作時以臺南選9號品種最強，其次爲臺農4號及78(S)-B-54，以澎湖2號最小。但秋作時則以澎湖2號品種固氮活性最大，臺農4號最小。試驗結果顯示同品種花生根瘤固氮活性與產量間有正相關存在，但固氮活性愈大之品種其產量不見得比固氮活性小之品種高。品種間之產量，春作及秋作均以78(S)-B-54最高，而以澎湖2號最低。澎湖7號花生品種就產量而言不適合在臺灣本島種植。每公頃施用140公斤之硫酸銨氮肥未能增進落花生產量。由各地篩選得到10株落花生根瘤菌，發現由元長、池上及南平、枷拿分離之根瘤菌與四品種花生有較強之親和性。四品種花生之中，以78(S)-B-54較易被分離純化之根瘤菌感染，其根瘤之固氮活性較高。There were significantly different nitrogenase activities among the four peanut varieties. In the Spring crop, the highest nitrogenase activities were recorded in cv. Tainan selection No. 9 and Tainon No. 4, and the lowest in cv. Penghu No. 2. However, in the Autumn crop, the highest nitrogenase activity was observed in cv. Penghu No. 2 and the lowest in Tainon No. 4. The results indicated that there was positive relationship between yield and nitrogenase activity of the same peanut variety. But a variety with higher nitrogen-fixing activity was not necessary with higher yield in the experiment. The highest yield was obtained in cv. 78(S)-B-54 and the lowest in cv. Penghu No. 2 in both Spring and Autumn crops. Penghu No. 2 peanut is not suitable to be cultivated in Taiwan. Nitrogen fertilizer of ammonium sulfate applied at 140kg/ha could not increase the yields of peanut. Ten strains of rhizobia isolated from various locations were inoculated with the four varieties of peanut, it was found that there were stronger affiliation between the rhizobia of Yuanchang, Chihshang, Nanping, Chiana and the four peanut varieties. A mong the four varieties, 78(S)-B-54 is much easily infected by the rhizobia, and its nitrogenase activity is much higher than the other's.
