The genus Yankee belongs to the leaf-like color leaf plant. Its coloration is very powerful in the landscape of the forest garden. It discusses the correlation between the light intensity and physiological and biochemical changes of the leaf color of cold water, and has important guidance for the selection of colorful leaf plant cultivation environment. The significance can lay a foundation for the cultivation and application of colorful plants in gardens in the future.
The test materials were cold flowers, leaves were opposite, and there were gray to silver-white stripes between the three main veins. The experiment selected cold-bloomed plants with good growth and disease-free leaves to reproduce in the house. Cold flowers are more cold-resistant, prefer warm and humid weather conditions, and are afraid of sunlight exposure. They have clear white and green leaves in shaded environments, short and compact internodes, and translucent and glossy leaves; they are often used in all shade environments. Loose. The test equipment includes intelligent light incubator, artificial climate box, digital illuminometer, and dual-beam UV-visible spectrophotometer. The test reagents were 2% methanolic hydrochloric acid, concentrated hydrochloric acid, 99% methanol, acetone, and ammonium molybdate.
Cut the top stem section of the cold water flower plant, cut about 15cm, keep the top 2-3 sections, cut off the lower leaves. The matrix is ​​used to disinfect and sterilize the sandy soil, and the matrix is ​​placed in a small pot with a height of about 10 cm. Two cut roots of the cuttings and the rooting powder of suitable concentration are inserted into the matrix. The first irrigation is performed at 23° C. Intelligent light incubator culture, pouring 2 times every 2d water, each 30 ~ 50mL, 8 ~ 10d hair rooting into seedlings. After growing new shoots, pay attention to topping, promote its branches, and make the plants more plump.
Through the observation of the experimental body in the intelligent light incubator, it was found that the total Chl. content in leaves of L. sinensis was higher than that of normal light treatment under shading condition, and was the lowest under strong light; the value of Chl.a/Chl.b was in shading. Under the condition of decreasing, anthocyanin content increased significantly under strong light induction, and negatively correlated with changes of Chl.; CAT activity increased under strong light and dark conditions, indicating that the antioxidant system was activated under high light stress. Visible, cold water flower has a strong resistance to negative, suitable for indoor and canopy closure of the larger environment.
