A drop of the tapped tree stand is observed in years 15 on DCA, S/2 d2 and S/3 d2 ET2.5%4/y treatments, although not statistically significant under our trial conditions (tables 7). This is mainly due to appearance of some tapping panel dryness when the tapping cut comes back downward to the renewed bark of DCA and S/2 d2.

Evolution of the tapped trees stand of tapping systems must therefore be strictly followed to see if this apparently negative evolution of the stand is temporary or permanent. cho mình hỏi từ stand ở câu đầu và câu cuối hiểu như thế nào cho đúng ?
