| Abstract: | Influence of ammonium and nitrate nitrogen on the growth of young beech plants Young beech plants were grown in aerated nutrient solutions with NH4 or NO3 nitrogen for a period of 12 weeks. pH-changes caused by the source of nitrogen were corrected every second day. Absorption of NH4-N was higher than of NO3-N. NH4-N was superior for shoot growth and development of lateral roots, NO3-N for growth of the main root. Nutrient solution containing both sources of nitrogen was the most favorable. |
