Effect of fertilizer treatment and acid misting on photosynthesis rate, carbohydrate content in needles and roots, and shoot and root growth of Norway spruce (Picea abies)



Effect of fertilizer treatment and acid misting on photosynthesis rate, carbohydrate content in needles and roots, and shoot and root growth of Norway spruce (Picea abies)



Forstwissenschaftliches Centralblatt 109(5): 264-274



In greenhouse experiments in a soil of low fertility, complete fertilizer treatment increased shoot dry matter production by up to 200% and root dry matter and root length by 100%, in both undamaged 3- to 4-yr-old Norway spruce and spruce damaged by acid misting. The effect of fertilizer treatment was much less marked on a soil of higher fertility, and the different growth responses on the two soils could be ascribed to net photosynthesis rates and carbohydrate contents in needles and roots.
