摘要:
通过环境调控提高石蒜产量、增加生物碱含量白光(CK)、红光(R)、蓝光(B)、红蓝复合光RB(1:2)、RB(2:1)RB(1:1),研究不同光质对石蒜幼苗生长、生理特性和生物碱积累的影响,筛选适合石蒜幼苗生长和生物碱积累的光质条件。结果表明:与CK相比,红蓝复合光RB(1:2)提高了10.91 %、146.48 %158.69 %、34.92 %和133.33 %;单一的红光不利于石蒜幼苗叶绿素的合成,一定比例的红蓝复合光能够促进叶绿素合成,RB(1:2)的处理RB(2:1)处理后,对石蒜幼苗可溶性糖的积累起到促进作用,蓝光能够提高其可溶性蛋白的含量;与CK相比,RB(1:2)处理下石蒜幼苗含量显著降低,和活性较低,说明RB(1:2)处理可以显著降低膜脂过氧程度;B处理下石蒜幼苗、和含量最高,分别是CK的1.84倍、1.62倍1.11倍。RB(1:2)处理RB(1:2)是石蒜幼苗的最佳生长光质条件,B处理蓝光可以促进石蒜生物碱的积累。
Abstract:
The experiment was conducted in order to explore the effects of different LED light quality on growth, physiological characteristics and alkaloids accumulations of Lycoris radiata seedlings, and to find the best light quality conditions for their growth and alkaloids productions through environmental regulation. Lycoris radiata seedlings were used as the experiment materials, and were cultured under different light emitting diodes (LEDs), including white light (CK), blue light (B), red light (R),and red and blue composite lights RB(1:2), RB(1:1), RB(2:1) to analyze the effects of different LEDs light qualities on growth, physiological characteristics of Lycoris radiata seedlings, so as to select the best LEDs quality for its growth and alkaloids productions. The results showed that: compared with the CK, the growth index of Lycoris radiata seedlings under red and blue composite lights were inproved, under RB(1:2) treatment, the plant fresh weight, plant dry weight, root length, root number, and bulb diameter were significantly increased by 158.69 %, 133.33 %, 10.91 %, 146.48 % and 34.92 %, respectively, compared to the CK; The R treatment had negetive effect on the biosynthesis of chlorophyll, a certain proportion of red and blue composite lights could promote chlorophyll synthesis, and RB (1:2) treatment had the highest chlorophyll content, which was 1.22 times higher than CK; RB (2:1) was beneficial to the accumulation of soluble sugar in Lycoris radiata seedlings, and blue light increased the content of soluble protein. Compared with CK, the MDA content, SOD and POD activities in Lycoris radiata seedlings under RB(1:2) treatment were significantly lower, indicating that RB (1:2) treatment could significantly reduce the degree of membrane lipid peroxidation. The galanthamine, lycorine and lycoramine contents of Lycoris radiata seedlings under B treatment were the highest, which were 1.84, 1.62 and 1.11 times higher than CK, respectively. In general, RB (1:2) treatment was beneficial to the growth, biomass accumulation as well as the synthesis of photosynthetic pigments of Lycoris radiata seedlings, and the degree of membrane lipid peroxidation was also low. RB (1:2) was the suitable light quality condition for the growth of Lycoris radiata seedlings. B treatment (blue light) could promote the accumulation of alkaloids. This study laid a theoretical foundation and technical support for the usage of LED light quality control technology in the production of high quality Lycoris radiata seedlings.
