The stems and leaves began to age to about two-thirds of the base of the planting tree. The yellowish stems and leaves were the period of accumulation of potato starch, which took 20-30 days. The stems and leaves stopped growing during this period, but the assimilation products continued to run in the tubers, and the tuber volume no longer increased, but the weight was still increasing, which was the main period of starch accumulation. The task of technical measures is to extend the lifespan of roots, stems and leaves as much as possible, slow down their decline, accelerate the transfer and accumulation of assimilate into the tuber, and fully mature the tubers.
