The species of flowers that enter into a deep state of sleep at high temperatures, such as Cyclamens, Lycoris, Pelargonium, Pericarpium, etc., showed in July that the stems and leaves of the aboveground were withered, and the underground nutrients withered to death, with underground stems or tuberous roots in the soil. Sleeping over summer. For flowers that are in deep hibernation, stop watering, move to a cool place, and keep the basin soil not too dry.
The type of flower that thrives, especially the foliage plants, such as cycads, peony, Monstera, rubber tree, Prynne, Jasmine, milan, zhulan, araucaria, bamboo worm, fruit pod, red ( Green) Gem, Hulk, Green Emperor, Green Queen, Whitefly, Brazilian Iron, Pachira, Camellia, Chamei, Peach, Torch, Poria, Lemon, Podocarpus, Pomegranate, Bauhinia, Wisteria, Chinese Rose, etc. Not only to increase the amount of watering and increase the number of watering, but also appropriate to give the foliage spray, spray combined. Especially when it comes to continuous cloudy days, because the air temperature is high and the air is dry, it is also necessary to give a water spray and must not be neglected. Once it is found that the potted soil is too dry and the leaves are wilting, first spray water on the leaves and wait until the leaves are straightened and restored, then give the roots watering, and do not pour the roots violently. Otherwise, it is very easy to cause the woody flowers to fall. ", Or cause the rot of the plant fibrous roots, and even cause the plant to die.
For potted plum piles, due to its flower bud differentiation period from July to August, appropriate "buckling of water" should be given to promote the normal differentiation of flower buds. The method is to keep the two sides of the potted plants curled slightly inward to control vegetative growth; if the vegetative growth of the shoots is not controlled, only two or three leaves can be extracted from the second new shoot, leaving only the base After one leaf was cut off, flower buds could still be differentiated between the leaves and the leaves.
In July, watering the potted plants should avoid several hours before and after the noon. Before 10 o'clock in the morning and watering after 4 o'clock in the afternoon, it is advisable to avoid excessive water temperature and soil temperature, affecting the growth of potted ornamental plants. If there is a continuous rainy weather in this month, check the flower pots immediately after the rain and find that the water in the pots has to be dumped in time. After the pot soil is a little dry, add loose soil once to avoid causing rot in the potted plants. .
The RNA purification kit is used to purify and recover RNA molecules transcribed in vitro and total RNA extracted from various materials, which can effectively remove contaminating impurities in RNA samples. The recovery rate of this product can reach 80%, and the OD260/OD280 ratio of the obtained RNA is generally about 2.0, which can be directly used in subsequent sensitive experiments (such as microarray analysis, fluorescence RT-PCR, etc.). With the deepening of transcriptomics, the complexity of RNA types, expression regulation and functions is far beyond our imagination.
Removing ribosomal RNAs that account for more than 80% helps to focus sequencing on less abundant but informative RNAs. At present, the removal of rRNA is mainly through the combined use of probe and RNase H. The processed RNA will be mixed with many digestion products, enzymes and ions, which is not conducive to the subsequent construction of RNA library. Take the Columnar RNA Purification Kit as an example. Trizol is a ready-to-use reagent that can be used to purify total RNA from tissues and cells. This is a single-phase solution of phenol and guanidine isothiocyanate that facilitates lysis of tissues and cells, inhibiting RNases to maintain RNA integrity.
