When plants are subjected to adverse environmental stress, they will increase the MDA content and soluble protein content of membrane lipid oxidation products. In the temperature experiment, with the increase of culture temperature, the higher the temperature, the higher the content of soluble protein and MDA content, indicating that the algae body has been subjected to more severe stress. Low salinity caused an increase in MDA content, indicating that the membrane lipids of the algae were more oxidized. In the intelligent artificial climate chamber experiment, a significant increase in soluble protein and MDA content in the high light experimental group was also found.
The different culture conditions of the intelligent artificial climate box have a significant effect on the photosynthetic pigments of the long leaf of the laver. In the temperature experiment, the Chl.a content of the algae was the highest at 20°C. The increase in temperature caused a decrease in the Chl.a content, but the phycobiliproteins showed an upward trend. With the increase of the Car content, the appearance of the algae was increased. red. Under low salt (<25) conditions, the contents of Chl.a, carotenoids, and phycobilisomes in the leaves of long-seaweed were all decreased, and the algae exhibited a lighter, lighter, thinner thickness and other characteristics. Physical photosynthesis capacity weakened. Low illumination will increase the content of Chl.a, R-PE and R-PC in the algae to obtain more energy. In light experiments, the Chl.a and R-PC contents of the leaves of long seaweed were found in the low light group. The rise.
After experiments in the intelligent artificial climate chamber, it was found that the Haematococcus larvae kept a relatively high relative growth rate under low light (≤6000 lx); under the light conditions of 9000 lx, algae remained relatively high for a short period of time (4 d). The growth rate, but then it dropped sharply, the algae decline quickly, indicating that the algae cells can no longer maintain normal growth.
backpacking and include mosquito netting along with pockets for nighttime storage. There are hammocks made
out of thin and lightweight material which makes them ideal for taking on day trips. Other hammocks include
self-standing metal or wood structures that support the hammock. Given that hammocks are commonly similar
lengths to accommodate for an average adult's height, most hammock stands are universal in design, typically
featuring a spreader bar that runs along the ground, feet for stability at each end, and a diagonal arm at each
end to provide two hanging points. Although they are usually bought premade, it is also possible to make your
own hammock.
For non-spreader-bar styles, the way in which they are hung is critical for comfort. Generally, a higher attachment
point is preferred as well as a sufficient length between points, though these two dimensions can be adjusted to
compensate for a lack in one or the other. The optimal angle of the attaching lines to the post/wall/tree is usually
about 30 degrees. Hammocks can be attached to the anchor points using a variety of suspension systems,
including ropes and webbing straps.
Changes of laver under different conditions in intelligent artificial climate chamber
Illumination is another important factor that affects the growth of algae. Illumination is the energy source for photosynthesis of plants and has important influence on plant growth, morphological structure, photosynthesis and metabolic activities. At suitable temperatures, the greater the illumination, the more energy the algae absorb, and the more photosynthetic products, the faster the algae growth. However, over the appropriate range of light will induce excess active oxygen, causing stress on the algae. The research on the change of laver by setting different conditions through the intelligent artificial climate box is as follows:
