Description

The physiological and biochemical changes and connections defining the starch accumulation in potato tubers are showed. Using the radioisotope C14O2 are analysed data on carbohydrates accumulation in leaves, speed of their movement in tubers, synthetic and decomposing enzyme activities in plant organs, the content of starch in tubers depending on the combination of fertilizers. The necessity for dose phosphorus application level not lower than nitrogen is reasoned. Recommendations on the optimal combination of macrofertilizers, ensuring compromise between yield and tuber starchiness for sod-podzoil sandy-loam and loamy, grey forest, peat, chernozem soils in dry-farming and irrigation are given

С использованием ра- диоизотопа С14О2 проанализированны данные по на- коплению углеводов в листьях, скорости их оттока в клубни, синтетической и расщепляющей деятельно- сти ферментов в органах растений, содержанию крахмала в клубнях в зависимости от сочетаний удоб- рений. Обоснованно положение о необходимости внесения доз фосфора на уровне не ниже азота. Даны рекомендации по оптимальным сочетаниям макроудобрений, обеспечивающим компромиссное решение между величиной урожая и крахмалитостью клубней для дерново-подзолистых супесчаных и суглинистых почв, серых лесных, тофяников, чер- ноземов на богаре и при орошении
