Changes in Soluble Sugar and Starch Content in Walnut Plantations of Different Ages
To study the internal stability of plant organs and the distribution ratios and interrelationships of various elements in different organs,this study selected four common walnut artificial forest age types in the Taihang Mountains of Hebei province,and measured the soluble sugar and starch content in the above ground and underground organs and tissues,analyzing their changing patterns.The results showed that the soluble sug-ar content in the above and underground organs and tissues of walnut plantations of different ages was higher than the starch content.As the age of the forest increases,the soluble sugar content in the leaves first de-creased and then increased.In the branches,it first rised and then fell.From the perspective of total amount,the treatment 1 had the highest content of soluble sugars and starch in the underground part.From the perspec-tive of forest age,the soluble sugar content gradually decreased with increasing forest age.From the measure-ment site,the soluble sugar content in the main root was the highest,and the regularity of starch content was not obvious.This result provides a reference for determining the limiting elements and nutrient utilization dur-ing the growth process of individual plants.
