【摘要】:薰衣草為唇形科矮小灌木,枝葉茂盛,花色艷麗,觀賞價(jià)值高,是布置花壇、花境,營造浪漫花海等景觀的植物材料。同時(shí)薰衣草也是具有高利用價(jià)值的芳香植物,是可貴的天然香料,其花、莖、葉乃至全株均有香氣,其中花的香氣最為突出,濃郁而柔和,沒有刺激感和毒副作用,因此被廣泛地應(yīng)用于食品、化妝品、醫(yī)藥等行業(yè)。目前世界各地都相繼對(duì)薰衣草進(jìn)行引種,學(xué)術(shù)界對(duì)于薰衣草引種、耐濕熱的研究越來越多,但大多以南方地區(qū)和新疆伊犁地區(qū)的薰衣草為主,對(duì)于內(nèi)蒙古地區(qū)的薰衣草的經(jīng)濟(jì)性產(chǎn)物及耐旱性研究卻鮮有報(bào)道,忽略了其地區(qū)多樣性。本文以內(nèi)蒙古地區(qū)栽培的不同品種薰衣草,即CAS01#齒葉薰衣草(Lavandula dentata),CAS 0 7#細(xì)葉薰衣草(Lavandula angutifolia)和 CAS 16#寬葉薰衣草(Lavandula latifolia)為實(shí)驗(yàn)對(duì)象,觀察其各自植物學(xué)特性;采用水蒸氣蒸餾法提取經(jīng)濟(jì)型產(chǎn)物(精油、純露),并通過GC-MS分析成分及各成分相對(duì)含量,從而評(píng)估產(chǎn)物品質(zhì);設(shè)置干旱脅迫觀察植物形態(tài),測(cè)定土壤濕度、丙二醛(MAD)含量、相對(duì)電導(dǎo)率(細(xì)胞膜透性)等指標(biāo),通過模糊數(shù)學(xué)隸屬函數(shù)法綜合分析其抗旱性。研究旨在豐富內(nèi)蒙古地區(qū)園林景觀材料,推動(dòng)薰衣草經(jīng)濟(jì)型產(chǎn)品產(chǎn)業(yè)化,為今后進(jìn)一步研究薰衣草提供了客觀的理論依據(jù)和科學(xué)參考。本論文研究結(jié)果如下:(1)內(nèi)蒙古不同品種薰衣草外觀形態(tài)有明顯差異:CAS01#和CAS16#可作為觀賞型灌木綠植,二者株高、冠幅較大,葉形、花色各具特點(diǎn);CAS07#株高、冠幅較小,花穗長,花粒緊簇,可作為矮小綠植裝飾花壇、花境。(2)內(nèi)蒙古不同品種的薰衣草經(jīng)濟(jì)型產(chǎn)物產(chǎn)量和理化性質(zhì)隨品種不同而不同。CAS01#:精油產(chǎn)率最低,成分種類最多,有效成分含量較少,品質(zhì)差;純露液質(zhì)渾濁,香味刺鼻,組分種類豐富,具有較強(qiáng)抗氧化活性,品質(zhì)一般。CAS07#:精油產(chǎn)率最高,成分種類最少,有效成分含量較多,比例合理,品質(zhì)較好;純露液質(zhì)清澈,香味宜人,組分種類適中,抗氧化活性最強(qiáng),品質(zhì)最好。CAS16#:精油產(chǎn)率居中,成分種類豐富,有效成分含量適中,品質(zhì)一般;純露液質(zhì)清澈,香味匱乏,組分種類單調(diào),抗氧化活性最弱,品質(zhì)最差。精油產(chǎn)率:CAS07#CAS16#CAS01#,精油品質(zhì):CAS07##CAS16##CAS01#,純露品質(zhì):CAS07#CAS01#CAS16##。(3)內(nèi)蒙古不同品種薰衣草在干旱脅迫中植株形態(tài)都出現(xiàn)葉片下垂,葉面卷曲、變細(xì)、褐化、發(fā)黃的現(xiàn)象,其中CAS07#生命力持續(xù)時(shí)間最長。隨著干旱脅迫時(shí)間延長,基質(zhì)土壤濕度逐漸下降,下降量:CAS16##CAS01#CAS07#;植物體內(nèi)MDA含量逐漸增多,增量:CAS16#CAS01#CAS07#;植株相對(duì)電導(dǎo)率逐漸變大,增量:CAS16#CAS01#CAS07#。通過多指標(biāo)模糊函數(shù)隸屬法綜合分析薰衣草抗旱性得出:CAS07#CAS01#CAS16#。綜上所述,CAS01#和CAS16#可作為觀賞類薰衣草培育,建植地被,美化環(huán)境。CAS07#具有可觀的經(jīng)濟(jì)價(jià)值和良好的耐旱性,所以該品種可以在內(nèi)蒙古干旱地區(qū)重點(diǎn)培育,推廣發(fā)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.
