用5种化学激发剂--6-苄基腺嘌呤(BA)、乙烯利(ETH)、茉莉酸甲酯(MeJA)、过氧化氢(H_2O_2)和氯化钙(CaCl2)处理1年生和5年生檀香树。评估它们对生长、心材形成和混凝土油合成的影响。结果表明，在BA和ETH诱导下，茎中一些新形成的枝条出现叶片衰老现象，并发育出新的较小的淡绿色叶片。在一年内，水处理树的心材中混凝土油的相对百分含量(0.65%)显著低于4 mM H_2O_2和4 mM BA处理的树(2.85%)和4 mM BA(2.75%)。4 mM BA、H_2O_2和CaCl2诱导的倍半萜含量显著高于2 mM诱导子处理的心材。4 mM MeJA处理的心材产生的倍半萜明显少于2 mM MeJA处理的心材。结合了形态、生理和色谱-光谱技术来追踪这些外源应用的化学激发子的潜在功能。这些结果可能会有重要的应用，并为更好地理解檀香树幼树心材形成和硬化的分子机制提供了更好的理解。
Five chemical elicitors––6-benzyladenine (BA), ethephon (ETH), methyl jasmonate (MeJA), hydrogen peroxide (H2O2) and calcium chloride (CaCl2)––were used to treat 1- and 5-year-old sandal trees (Santalum album L.) to assess their effects on growth, heartwood formation and concrete oil synthesis. The results showed that some newly formed branches in stems that were induced by BA and ETH displayed leaf senescence and developed new smaller and light-green leaves. The relative percentage of concrete oil from the heartwood of water-treated trees (0.65%) was significantly lower than that from trees treated with 4 mM H2O2 (2.85%) and 4 mM BA (2.75%) within one year. Four mM BA, H2O2 and CaCl2 induced a significantly higher level of sesquiterpenoids than heartwood treated with 2 mM of these elicitors. Four mM MeJA induced significantly less sesquiterpenoids than heartwood treated with 2 mM MeJA. Morphological, physiological, and chromatographic–spectrometric technologies were integrated to trace the potential function of these exogenously applied chemical elicitors. The results may have important applications and provide a better understanding of the molecular mechanism of heartwood formation and hardening in young sandalwood trees.
