盆栽黑麦草施用PP333后，叶色深绿，株高降低．单株分蘖数及叶片数增多，根／冠比升高；植株地上部中的蛋白质含量增加，而根系中则有所降低；地上部光合产物向根系的运输加强。
After the application of PP333 in potted ryegrass, the leaf color is dark green and the plant height is reduced. The number of tillers per plant and the number of leaves increased, and the ratio of root / shoot increased. The content of protein in shoots increased, but decreased in roots. The transport of photosynthate to shoots increased.
