为探究施钙对降香黄檀心材抽提物的影响,为其人工林高效培育提供参考,以 6 年生降香黄檀为研究对象,采用注射 CaCl2 溶液和填埋 Ca(OH)2 固体 2 种不同施钙方式,分析不同钙施加量对心材抽提物的影响.结果表明:注射CaCl2 溶液后,降香黄檀心材抽提率、黄酮类化合物和挥发油类化合物的含量具有明显提升,且随溶液浓度的提高,促心材抽提物效果变差;填埋 Ca(OH)2 固体后,降香黄檀心材抽提率基本不变,黄酮类化合物和挥发油类化合物含量降低.注射CaCl2 溶液具有较好的促心材抽提物形成效果,以 2%浓度为宜;填埋Ca(OH)2 固体未发现有促心材抽提物形成的效果.
The Effect of Calcium Application on the Formation of Heartwood in Dalbergia odorifera
To investigate the effect of calcium application on the formation of the heartwood of Dalbergia odorifera and pro-vide a reference for the efficient cultivation of artificial forests,this study investigated 6-year-old D.odorifera plants.Two different calcium application methods,namely,the injection of CaCl2 solution and the landfill of Ca(OH)2 solid,were used to analyze the impact of various application amounts on the heartwood extract.The results showed that after injection of CaCl2 solution,the extraction rate,flavonoid content,and volatile oil content of D.odorifera heartwood significantly increased,and the effect of promoting heartwood formation decreased with increasing solution concentration.After filling with Ca(OH)2 solid,the extraction rate of D.odorifera heartwood remained unchanged,while the content of flavonoids and volatile oil compounds decreased.CaCl2 solution injection has promoted the heartwood formation well,with a suitable concentration of 2%.However,no effect on promoting heartwood formation was found in the Ca(OH)2 solid landfill.
