摘要
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CaCl_(2)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CaCl_(2)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CaCl_(2)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。
To investigate the effect of calcium application on the formation of the heartwood of Dalbergia odorifera and provide 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 CaCl_(2) 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 CaCl_(2) 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.CaCl_(2) 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.
