Abstract

Plant-derived smoke has been known to play an important role in distribution and growth of vegetation. Using a proficiently designed furnace, we extracted smoke from the leaves of four plant viz. ,,, and . Smoke dilutions obtained from these plants were obtained in different concentrations to identify potential lettuce growth promoting smoke solution. Results revealed that smoke obtained from significantly enhanced the lettuce seed germination. This solution was then partitioned into ethyl acetate, dichloromethane, -hexane, chloroform and ether fractions. Ethyl acetate fraction was found to be potent to enhance seed germination. This fraction was subjected to column chromatography and spectroscopic techniques to obtain compound . This compound was identified as hydroquinone using 1D and 2D NMR techniques. At low concentrations (5, 10, and 20 ppm), compound enhanced the lettuce seed germination; however, higher concentrations inhibited its growth as compared to control.

摘要

植物源烟雾在植被的分布和生长中发挥着重要作用。我们使用精心设计的炉子，从四种植物即[此处原文缺失植物名称]、[此处原文缺失植物名称]、[此处原文缺失植物名称]和[此处原文缺失植物名称]的叶子中提取烟雾。从这些植物中获得的烟雾稀释液有不同浓度，以确定促进生菜生长的潜在烟雾溶液。结果表明，从[此处原文缺失植物名称]获得的烟雾显著提高了生菜种子的发芽率。然后将该溶液分离为乙酸乙酯、二氯甲烷、正己烷、氯仿和乙醚馏分。发现乙酸乙酯馏分能有效提高种子发芽率。对该馏分进行柱色谱和光谱技术分析以获得化合物[此处原文缺失化合物名称]。使用一维和二维核磁共振技术将该化合物鉴定为对苯二酚。在低浓度（5、10和20 ppm）下，化合物[此处原文缺失化合物名称]提高了生菜种子的发芽率；然而，与对照相比，较高浓度抑制了其生长。
