  瞭解接種菌根菌對不同番茄品種感染及苗期生育健化情形並進一步瞭解接種菌根菌與不同化學肥料施用量對番茄生育與產量的影響。二品種接種內生菌根菌之菌根苗感染率分別台中亞蔬十號59.9%與種苗七號 55.7%。幼苗生長勢方面,地上部與地下部鮮、乾重除台中亞蔬十號地下部鮮重外,兩品種均以接菌處理較無接菌者佳。定植一個月後菌根植株的生育調查顯示,除台中亞蔬十號接菌加農友慣行施肥量處理較無接菌者差外,其餘處理均以接種菌根菌較無接菌者有較佳生長勢。接菌與不同化學肥料處理植體元素含量除磷含量,兩品種均以接菌加化學磷肥半量較其他處理高外,其餘元素不同處理互有高低。接種菌根菌對番茄果實產量與品質之影響,資料顯示兩品種無論接菌與否加不同施肥量產量高於農友慣行施肥區,其中又以種苗七號接菌化學磷肥半量產量最高,且接菌較未接菌者佳,台中亞蔬十號則以台中亞蔬十號未接菌化學肥料全量較高,顯示接種菌根菌後增產效果並不穩定。果實品質方面兩品種化肥按推薦量與磷肥減半均較農友慣行施用量有較高糖度,又以台中亞蔬十號接菌化學肥料全量品質最佳。番茄穴植盤菌根苗在缺水逆境下之影響,試驗結果顯示兩品種無論在正常供水與水分逆境下接種菌根菌地上部與地下部之鮮、乾重均較無接菌者為佳,顯示接種菌根菌對兩品種番茄植株生長有所助益,亦發現兩品種番茄在缺水逆境下果實產量均較正常供水低,其中又以有接菌正常供水產量較佳。

Evaluation and Utilization of Endomycorrhiza to the Growth of Tomato under Stress Conditions

Huang, J. C., C. C. Lin and S. N. Huang

Abstract

  This experiment is attempted to explore the effect of endomycorrhizal fungi Glomus spp. and the effect of endomycorrhiza plus different amount of chemical fertilizers on the growth and yield of tomato. Results showed that the infection rates by Glomus spp. On the two tomato varieties Taichung AVROC NO.10 and Taiwan seed service NO.7 were 59.9 ﹪ and 55.7 ﹪ ,respectively. Higher fresh and dry weight of the above-ground parts in the plants of the two varieties inoculated with Glomus spp. For the under-ground parts, the variety TSS NO. 7 also was found with higher fresh and in the Glomus inoculated plants. However, in the Taichung AVROC NO.10 dry weight is also better, but not the fresh weight. For the content of phosphorus, height amount was found in the plants inoculated with Glomus plus half-amount of phosphorus-containing chemical fertilizers. The content of the other elements varied among all treatments. Data of the fruit yield revealed that all treatments inoculated with Glomus spp. plus application of chemical fertilizers were higher than that of the conventional method used by the famers with chemical fertilizers only. Best yield was found is the variety TSS NO.7 inoculated with Glomus plus application half-amount of P- fertilizer. However, in the variety Taichung AVROC NO.10, best yield was found in the treatment with full amount of chemical fertilizers without inoculation of Glomus . Therefore, whether or not, the inoculation of Glomus will increase the fruit yield should be further studied. Higher sugar content was found in the treatment with recommended amount of chemical fertilizer plus half-amount of P- fertilizer. Best yield was found in the variety Taichung AVROC NO.10 inoculated with Glomus plus full amount of chemical fertilizers.Plant growth was found better in the treatments inoculated with Glomus whether it is under water stress or not, and the plants with sufficient water yieled better than those under water stress. Best yield was found in the treatment with sufficient water plus inoculation of Glomus .
