This indicated that the resin excreting speed of pines was negatively correlated with disease resistance to Bursaphelenchus xylophilus. 因此，樹(shù)干泌脂速度或樹(shù)脂含量可能是評價(jià)松樹(shù)對松材線(xiàn)蟲(chóng)病抗性的重要性狀之一。
Besides, the trace observations on the amount of B. xylophilus into pine twigs revealed that the peak period of nematode transmission advanced in higher temperatures. 通過(guò)對松褐天牛取食傳入松枝的松材線(xiàn)蟲(chóng)量的追蹤記錄發(fā)現，隨著(zhù)溫度的升高，傳播線(xiàn)蟲(chóng)的高峰時(shí)段隨之提前。
