Nitrogen nutrition and cytokinin activity in Solanum tuberosum

Nitrogen nutrition and cytokinin activity in Solanum tuberosum - Physiologia Plantarum, 42(2), p.185-189, 1978 .

In water culture experiments with potato plants (Solanum tuberosum L. cv. Ostara), the influence of continuous nitrogen nutrition (constant supply of NO3-)and discontinuous nitrogen nutrition (interruption of NO3- supply, i. e., nitrogen withdrawal for 6 days)on the endogeneous cytokinin level in the roots, shoots and exudate of decapitated plants was studied. Harvests took place at intervals of 3 days. The chlorophyll formation test (cucumber cotyledons)and soya callus test were used to determine the cytokinin activity.
