【摘要】：薰衣草为唇形科矮小灌木,枝叶茂盛,花色艳丽,观赏价值高,是布置花坛、花境,营造浪漫花海等景观的植物材料。同时薰衣草也是具有高利用价值的芳香植物,是可贵的天然香料,其花、茎、叶乃至全株均有香气,其中花的香气最为突出,浓郁而柔和,没有刺激感和毒副作用,因此被广泛地应用于食品、化妆品、医药等行业。目前世界各地都相继对薰衣草进行引种,学术界对于薰衣草引种、耐湿热的研究越来越多,但大多以南方地区和新疆伊犁地区的薰衣草为主,对于内蒙古地区的薰衣草的经济性产物及耐旱性研究却鲜有报道,忽略了其地区多样性。本文以内蒙古地区栽培的不同品种薰衣草,即CAS01#齿叶薰衣草(Lavandula dentata),CAS 0 7#细叶薰衣草(Lavandula angutifolia)和 CAS 16#宽叶薰衣草(Lavandula latifolia)为实验对象,观察其各自植物学特性;采用水蒸气蒸馏法提取经济型产物(精油、纯露),并通过GC-MS分析成分及各成分相对含量,从而评估产物品质;设置干旱胁迫观察植物形态,测定土壤湿度、丙二醛(MAD)含量、相对电导率(细胞膜透性)等指标,通过模糊数学隶属函数法综合分析其抗旱性。研究旨在丰富内蒙古地区园林景观材料,推动薰衣草经济型产品产业化,为今后进一步研究薰衣草提供了客观的理论依据和科学参考。本论文研究结果如下:(1)内蒙古不同品种薰衣草外观形态有明显差异:CAS01#和CAS16#可作为观赏型灌木绿植,二者株高、冠幅较大,叶形、花色各具特点;CAS07#株高、冠幅较小,花穗长,花粒紧簇,可作为矮小绿植装饰花坛、花境。(2)内蒙古不同品种的薰衣草经济型产物产量和理化性质随品种不同而不同。CAS01#:精油产率最低,成分种类最多,有效成分含量较少,品质差;纯露液质浑浊,香味刺鼻,组分种类丰富,具有较强抗氧化活性,品质一般。CAS07#:精油产率最高,成分种类最少,有效成分含量较多,比例合理,品质较好;纯露液质清澈,香味宜人,组分种类适中,抗氧化活性最强,品质最好。CAS16#:精油产率居中,成分种类丰富,有效成分含量适中,品质一般;纯露液质清澈,香味匮乏,组分种类单调,抗氧化活性最弱,品质最差。精油产率:CAS07#CAS16#CAS01#,精油品质:CAS07##CAS16##CAS01#,纯露品质:CAS07#CAS01#CAS16##。(3)内蒙古不同品种薰衣草在干旱胁迫中植株形态都出现叶片下垂,叶面卷曲、变细、褐化、发黄的现象,其中CAS07#生命力持续时间最长。随着干旱胁迫时间延长,基质土壤湿度逐渐下降,下降量:CAS16##CAS01#CAS07#;植物体内MDA含量逐渐增多,增量:CAS16#CAS01#CAS07#;植株相对电导率逐渐变大,增量:CAS16#CAS01#CAS07#。通过多指标模糊函数隶属法综合分析薰衣草抗旱性得出:CAS07#CAS01#CAS16#。综上所述,CAS01#和CAS16#可作为观赏类薰衣草培育,建植地被,美化环境。CAS07#具有可观的经济价值和良好的耐旱性,所以该品种可以在内蒙古干旱地区重点培育,推广发展。
[Abstract]:Lavender is a small shrub of the family Labiatae, with luxuriant branches and leaves, colorful flowers and high ornamental value. It is a plant material for arranging flower beds, flower enclaves, creating romantic flower seas, etc. Lavender is also a fragrant plant with high utilization value. It is a precious natural spice, its flowers, stems, leaves and even the whole plant have aroma, the aroma of which is the most prominent, rich and soft, without irritation and toxic side effects, so it is widely used in food, cosmetics, Medicine and other industries. At present, lavender has been introduced to various parts of the world one after another. More and more research has been done in academia on the introduction of lavender and its resistance to moisture and heat, but most of it is lavender in the southern region and the Yili region of Xinjiang. The economic products and drought tolerance of lavender in Inner Mongolia are seldom reported and the diversity of lavender is neglected. CAS01# lavender and CAS 16# lavender were used to observe their botanical characteristics, and to extract economic products (essential oil, essential oil, essential oil, etc.) by steam distillation. The product quality was evaluated by GC-MS analysis of components and relative contents of each component, plant morphology was observed under drought stress, soil moisture, malondialdehyde (MDA) content, relative conductivity (membrane permeability), and so on. The drought resistance of lavender was comprehensively analyzed by membership function method of fuzzy mathematics. The purpose of the study was to enrich the garden landscape materials in Inner Mongolia and to promote the industrialization of lavender economic products. The results are as follows: (1) there are obvious differences in the appearance and morphology of lavender species in Inner Mongolia. They can be used as ornamental shrub green plants, and the plant height of the two species is higher than that of the other two species of lavender, the results are as follows: (1) there are obvious differences in the appearance and morphology of lavender in different varieties of Inner Mongolia. The height of CAS07# plant is larger, the leaf shape is larger, the flower color is different, the crown is smaller, the flower ear is long, the flower grain is tight and cluster, so it can be used as the flower bed of the dwarf green plant. The yield and physical and chemical properties of lavender economic type products of different varieties in Inner Mongolia varied with variety. CAS01: #S01: the yield of essential oil was the lowest, the composition was the most, the content of active components was less, and the quality was poor. The essential oil yield is the highest, the composition is the least, the effective component content is more, the proportion is reasonable, the quality is good, the pure dew liquid quality is clear, the flavor is pleasant, the composition is moderate, the quality is clear, the flavor is pleasant, the composition is moderate, the quality of pure dew is clear, the flavor is pleasant, and the composition is moderate. The antioxidant activity is the strongest, the quality is the best, the yield of essential oil is in the middle, the composition is rich, the effective component content is moderate, the quality is average, the pure dew liquid is clear, the aroma is scarce, the component is monotonous, and the antioxidant activity is the weakest. The yield of essential oil was 1: CAS07 #CAS16 #CAS01 #1.The quality of essential oil was 1% CAS07 #CAS16 #CAS01 #CAS01 #CAS01 #CAS16 ######.3) under drought stress, different varieties of lavender in Inner Mongolia showed leaf drooping, leaf surface curl, fining, browning and yellowing. With the extension of drought stress time, the soil moisture of the substrate decreased gradually, and the MDA content in the plant increased gradually, and the relative electrical conductivity of the plant gradually increased. Increment: CAS16 #CAS01#CAS07#.Through analyzing the drought resistance of lavender by multi-index fuzzy function method, we can draw a conclusion: CAS07#CAS01# and CAS16# can be used as ornamental lavender cultivation, planting land cover, beautifying environment. CAS07# has considerable economic value and good drought resistance, in summary, the #CAS16 #CAS16#CAS01# and #CAS16#CAS16#CAS01# can be used as ornamental lavender. Therefore, the variety can be cultivated in arid areas of Inner Mongolia, promotion and development.
