Abstract

Leaf of Cinnamomum longipaniculatum contains around 60 % essential oil (EO) being 1,8-cineole the main component. This is the biggest EO producing tree species in China and Sichuan of China has a plantation of 36 000 ha. Despite many studies, EO content of very young leaves and its variation of a full year is understudied and the effects of different habitats and insect herbivore on EO yield is poorly understood. A 12-month long, half-month interval monitoring of leaf EO content in an industrial farm revealed an EO content ranging from 2.06 % to 4.25 %. Half-monthly EO content varied from 1.76 % in early March to 2.75 % in early September in fresh leaves, and from 2.55 % in late October to 4.13 % in early April in dry leaves. Leaf EO content was significantly higher in dry than in fresh (3 % versus 2.03 %), two-year old than one-year old (3.06–4.25 % versus 2.06–3.22 %) leaves. EO content differed significantly on different slope aspects (3.87 % on southwest, 3.52 % on southeast, 3.26 % on east, and 2.85 % on northwest), and on different slope gradients (2.99 % on 0–10° slopes, 3.27 % on 10–20° slopes, 3.80 % on 20–30° slopes). Insect herbivore significantly increased EO content and it was 2.91–3.63 % in damaged versus 2.06–3.22 %) in undamaged leaves. Results indicate that plantations on marginal lands with thin, poor and dry soils on steep slopes not only produce higher EO yield but does not compete with cereal crops for croplands. Fertilizers, insecticides and irrigation are unnecessary. This study provides important information for design and management of C. longipaniculatum plantations.

生境和草食胁迫对长尖香樟精油产量的影响

肉桂叶含有约60%的精油（EO），主要成分为1,8-桉树脑。这是中国最大的EO生产树种，中国四川有36000公顷的人工林。尽管进行了大量的研究，但对极幼叶的EO含量及其全年变化的研究尚不充分，对不同生境和昆虫食草性对EO产量的影响了解甚少。对某工业化农场叶片EO含量进行了为期12个月、间隔半个月的监测，发现EO含量在2.06% ~ 4.25%之间。鲜叶中EO含量在3月初为1.76% ~ 9月初为2.75%，干叶在10月下旬为2.55% ~ 4月初为4.13%。干叶EO含量显著高于鲜叶（3%比2.03%），2年龄叶显著高于1年龄叶（3.06 - 4.25%比2.06 - 3.22%）。EO含量在不同坡向（西南3.87%，东南3.52%，东3.26%，西北2.85%）和不同坡度（0-10°为2.99%，10-20°为3.27%，20-30°为3.80%）上差异显著。草食昆虫显著提高了EO含量，受损叶片的EO含量为2.91 ~ 3.63%，而未受损叶片的EO含量为2.06 ~ 3.22%。结果表明，在陡峭、贫瘠、干燥的边缘土地上种植，不仅能获得较高的作物产量，而且不会与谷类作物争夺耕地。化肥、杀虫剂和灌溉都是不必要的。该研究为长藤人工林的设计和管理提供了重要信息。

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
