epinephrin

While the fruits ripening process was delayed in leetrl antisense fruits . epinastic of leaves in leetrl antisense plants was only occasionally observed , which was not observed in leetr2 antisense plants ; ( 5 ) when treated by exogenous ethylene ( 25ul / l ) , the abscission of antisense leetr2 petiole explants was delayed . moreover , leaf epinasty failed to be induced by ethylene treatment c , which suggested that these tissues were insensitive to ethylene ( 5 )植株衰老和葉片脫落延遲,花瓣脫落也明顯的延遲,在轉反義leetr1基因番茄的果實成熟特性被明顯改變,表現在乙烯釋放高峰延遲,果實顏色出現變異,以及和成熟相關的酶活性的改變,然而,轉反義leetr2基因的果實的成熟特性與對照相比無明顯差別。

Epinasty ( epinastic movements ) a nastic movement that involves the curving of a plant organ away from the axis ( i . e . downward ) as a result of greater growth on the upper surface , as in the opening of flowers 偏上性生長(偏上性運動) :植物開花時由于上表面生長較快而引起植物器官彎曲并偏離軸向的向性運動(如向下) 。
