PP333%高羊茅%须根%根系活力
PP333%高羊茅%鬚根%根繫活力
PP333%고양모%수근%근계활력
PP333%Festuca elata%fibrous root%plant root vigor
探讨了PP333对草坪草高羊茅的生长发育和生理效应的影响.结果表明,适宜浓度的PP333可有效抑制生长,促进须根的发生,提高根冠比;抑制生殖生长,提高根系活力,增加细胞中可溶性糖的含量,提高叶绿素a/b值,增强抗逆能力.
探討瞭PP333對草坪草高羊茅的生長髮育和生理效應的影響.結果錶明,適宜濃度的PP333可有效抑製生長,促進鬚根的髮生,提高根冠比;抑製生殖生長,提高根繫活力,增加細胞中可溶性糖的含量,提高葉綠素a/b值,增彊抗逆能力.
탐토료PP333대초평초고양모적생장발육화생리효응적영향.결과표명,괄의농도적PP333가유효억제생장,촉진수근적발생,제고근관비;억제생식생장,제고근계활력,증가세포중가용성당적함량,제고협록소a/b치,증강항역능력.
In response to applied PP333 solution on a optimum concentration of 200 mg/L,plant growth and reproductive development of tall fescue(Festuca elata)were inhibited.Treated with the solution,plant root vigor,the number of fibrous root,root to crown weight ratio,chlorophyll a to b content ratio,soluable sugar level in cells and plant stress resistance ability were all increased.
