    16 experiments with lavender gland hairs (secreting
    )Lavandula angustifolia is a lip-shaped plant with square stems and leaf-to-leaf. Its stems, leaves, and flowering epiderms all have multiple cells of aden hair, especially on the flower. In addition to the aden hair on the epithet, there are many branches of the epithet, the gland hair is under the epithet.take the flowers of lavender that are flowering or have not yet blossomed and make
    to observe. There are many multicellular epitheliotes branched on the epitheliotes on the outside of the sliver (because the flowers are combined into a barrel) and multicellular aden hairs can also be seen. These glands are divided into two parts, the head is composed of 5-8 cells, the handle is composed of one or two cells (Figure 16-1).In mature adenoblast cells, volatile aromatic oil accumulates between the top wall of the cell and the layer, which is easy to see clearly. If the flower is cut vertically so that its outer skin is up, it is tiled on a dripping water slide, covered with a slide, and observed under a low-fold object lens. The epithets of the branches are dense, and aden hairs can be seen beneath the epicarptic fur. From the top, the adenoid head is made up of several cells, each of which is triangular, with curved edges on the outside and several cells arranged in a radioactive form. If viewed with a high-fold object lens, turn the fine focuser, you can vaguely see the following shank cells. The puffed layer of mature adenoid hair is half-moon shaped.for observation, volatile aromatic oils can be dyed orange-red and the boundaries between the layer and the cell wall are clearer by sultan III. staining or Sudan IV. At the same time of observation, touch the leaves or flowers of lavender with your hands, smell your fingers, and you will feel an aromatic smell.If you use the preserved dried lavender sashure as an experimental material to observe its aden hair, you can tile the flowers to be seen on the slide, preferably with Sudan III. or Sudan IV. It can solve the problem of lack of material when doing this experiment in winter, but the effect is not as good as fresh material.
