| Abstract: | During potato tuber enlargement stage applying paclobutrazol (effective constituent 20 g/mu) , can inerease the chlorophyl content by 22.8%, net photosynthetic intensity by 56.7%, inhibit vegetative growth of the parts above ground, promot distribution of photosynthate to potato tuber. Economic efficiency increased by 68.7%, the percentage of larger-size tuber increased remarkably, as a result, potato yield and commercial value are both higher. |
