【摘要】:茄子(Solanum melongena L.)在我國(guó)的栽培面積逐年擴(kuò)大,是我國(guó)內(nèi)銷及出口創(chuàng)匯的主要蔬菜之一。前期研究發(fā)現(xiàn),在光強(qiáng)一致條件下,紅色棚膜有利于培育壯苗和茄子的生長(zhǎng)發(fā)育。但不同顏色棚膜下其光譜組成較復(fù)雜,很難進(jìn)一步深入研究其具體調(diào)控機(jī)理。發(fā)光二極管(Light Emitting Diode,簡(jiǎn)稱LED)具有單色、發(fā)熱少、單體尺寸小、壽命長(zhǎng)、無(wú)污染等諸多優(yōu)點(diǎn),同時(shí)LED解決了棚膜研究中光質(zhì)不純的問(wèn)題,增加了試驗(yàn)的可靠性。本文以?布利塔?長(zhǎng)茄為試材,采用LED精量調(diào)制光質(zhì)和光強(qiáng),以白光為對(duì)照,探討了紅光、藍(lán)光和紅藍(lán)組合光對(duì)茄子生長(zhǎng)發(fā)育及產(chǎn)量、品質(zhì)的影響,以期為茄子壯苗培育及優(yōu)質(zhì)高產(chǎn)進(jìn)行光環(huán)境調(diào)控提供理論依據(jù),主要研究結(jié)果如下:1.紅藍(lán)組合光處理下茄子幼苗莖粗、葉面積、地上和地下部干重、根冠比、壯苗指數(shù)、葉片厚度、柵欄組織厚度以及根系活力均最大;與對(duì)照相比,紅光、藍(lán)光處理下茄子幼苗莖粗、地上和地下部干重、根冠比、壯苗指數(shù)、柵欄組織厚度及根系活力均較低,其中紅光下最低。隨定植天數(shù)延長(zhǎng),在結(jié)果期,紅光處理下莖粗、葉面積最大;藍(lán)光處理下根干重及根系活力最大;對(duì)照下全株干重及地上部干重最大。2.光質(zhì)影響植物的氮代謝過(guò)程,調(diào)節(jié)植物碳水化合物和蛋白質(zhì)的代謝。藍(lán)光處理下茄子幼苗葉片全氮、可溶性蛋白和游離氨基酸含量均最大,較對(duì)照分別提高55.2%、26.6%和5.5%。紅藍(lán)組合光處理下可溶性糖含量最高,其次為紅光處理。3.紅藍(lán)組合光處理下茄子幼苗葉片光合色素含量、凈光合速率和ΦPSII均最高;藍(lán)光下葉綠素a/b、Fv/Fm、qP最大;而紅光處理下均最低。結(jié)果期,對(duì)照下光合色素含量較高;紅藍(lán)組合光處理下凈光合速率、蒸騰速率、氣孔導(dǎo)度、Fv/Fm、ΦPSII和qP均最大;而紅光下均最低。4.藍(lán)光處理下,茄子果肉中可溶性蛋白、游離氨基酸和茄皮中花青素含量顯著高于其他處理,但果肉中類黃酮和總酚含量較低;紅光處理下,茄皮中類黃酮含量最高,但果肉中維生素C(Vc)和可溶性蛋白含量最低;紅藍(lán)組合光處理下,果肉中可溶性糖及茄皮中總酚、紅色素、黃色素含量和總抗氧化能力及產(chǎn)量均顯著高于其他處理;而對(duì)照白光處理下,果肉中Vc、類黃酮和總酚含量及總抗氧化能力最高。
[Abstract]:Solanum melongena L. The cultivated area in our country expands year by year, and it is one of the main vegetables for domestic sale and export. It was found that under the condition of the same light intensity, the red greenhouse film was beneficial to the growth and development of strong seedling and eggplant. However, the spectral composition of different color greenhouse films is complex, so it is difficult to further study the specific regulation mechanism. Light Emitting diode (LED) has many advantages, such as monochromatic, less heating, small size, long life, no pollution and so on. At the same time, LED solves the problem of light quality impurity in the study of greenhouse film and increases the reliability of the experiment. This article? Britta? The effects of red light, blue light and red blue combination light on the growth, development, yield and quality of eggplant were studied by LED precision modulation of light quality and intensity. In order to provide theoretical basis for the cultivation of strong seedlings and the regulation of light environment with good quality and high yield, the main results are as follows: 1. The stem diameter, leaf area, dry weight of aboveground and underground parts, root-shoot ratio, seedling index, leaf thickness, thickness of palisade tissue and root activity of eggplant seedlings under red and blue combination light treatment were the largest. The stem diameter, dry weight of aboveground and underground parts, root-shoot ratio, strong seedling index, thickness of palisade tissue and root activity of eggplant seedlings under blue light treatment were lower than those under red light. With the extension of planting days, under red light treatment, stem diameter, leaf area was the largest; under blue light treatment root dry weight and root activity was the largest; under the control, the whole plant dry weight and shoot dry weight was the largest. 2. Light affects nitrogen metabolism and regulates carbohydrate and protein metabolism in plants. The contents of total nitrogen, soluble protein and free amino acid in the leaves of eggplant seedlings under blue light treatment were the highest, and the contents of total nitrogen, soluble protein and free amino acids were increased by 55.226.6% and 5.5%, respectively, compared with the control. The content of soluble sugar was the highest under the combination of red and blue light, followed by red light treatment. 3. The photosynthetic pigment content, net photosynthetic rate and 桅 PSII of eggplant seedlings under red and blue combination light treatment were the highest. The net photosynthetic rate, transpiration rate, stomatal conductance (FV / Fm), 桅 PSII and QP were the highest in red and blue combination light, while the lowest in red light. The contents of soluble protein, free amino acid and anthocyanin in eggplant pulp were significantly higher than those in other treatments, but the contents of flavonoids and total phenols were lower under blue light treatment, but the flavonoids content in eggplant peel was the highest in red light treatment. However, the contents of vitamin C (VC) and soluble protein in pulp were the lowest, and the contents of soluble sugar and total phenol, red pigment, yellow pigment, total antioxidant ability and yield in fruit pulp were significantly higher than those in other treatments under the combination of red and blue light. The contents of Vc, flavonoids, total phenols and total antioxidant capacity in pulp were the highest in white light treatment.
