Stem Cell Research Opens a Second Front for the Cloning Sheep Technology Route
The Leap from Sheep to Monkey Without the two papers published on November 20, Shoukhrat Mitalipov would have been the most watched stem cell research scientist during this period. On November 14, this scientist at the Oregon National Primate Research Center in the United States published a paper in Nature, announcing that he had successfully obtained cloned rhesus monkey embryos. This was the first time scientists had cloned viable

Diagnosis and Treatment Experience of Secondary Infection with Hemotropic Mycoplasma (Eperythrozoon) in Canine Distemper
Canine distemper mainly affects young dogs, and its pathogen is canine distemper virus. Affected dogs are characterized by a biphasic fever pattern, rhinitis, severe digestive tract disorders and respiratory tract inflammation. However, cases of mixed infection of canine distemper and canine hemotropic mycoplasma (Eperythrozoon) are relatively rare. 1 Onset and Symptoms The affected dog was 8 months old, clinically diagnosed with canine distemper, with a disease course of 1 week, and had already been treated with canine pentavalent serum, antibiotics, etc. When it came to our hospital for treatment, it was confirmed to have secondary lobar pneumonia, with a body temperature of 40.6 degrees C, showing a biphasic fever pattern (that is, at the beginning of the disease the body temperature rises to about 40 degrees C

Causes of Secondary Growth in Garlic and How to Prevent and Control It
Garlic is one of the indispensable vegetables in people's daily lives, and it is also a popular vegetable that can be supplied year-round on the market. However, in recent years, due to improper planting methods, management practices, and other factors, a large amount of secondary growth in garlic has appeared, commonly known as "horsetail garlic" or "bread garlic," which makes the garlic unsuitable both for seed saving and for eating, severely reducing its marketability and economic benefits. What exactly causes secondary growth in garlic, and how should it be prevented and controlled? The author

What causes secondary branching and deformed scapes in garlic? Here's how to prevent it
Every year during the scape-elongation stage of garlic, a certain proportion of garlic plants develop secondary branching and deformed scapes, seriously affecting the yield and quality of garlic scapes. In recent years, we have carried out investigations and research, and have explored effective agricultural measures to control the occurrence of secondary branching and deformed scapes in garlic, which have played a very significant role in improving the economic benefits of garlic growers. 1 The harm caused by secondary branching and deformed scapes in garlic. Secondary branching in garlic is also called secondary growth or branching, and growers call it "horsetail garlic". There are generally two phenomena: first, branches differentiate from the outer leaf sheath,

How to efficiently utilize the second crop of Oriental lily flowers
Oriental lily bulbs are generally grown for only one crop abroad, then dug up and discarded. Based on China's national conditions, Chinese lily growers have developed a reuse technique for Oriental lily bulbs, which is now applied in many places. However, because the second-crop flowers produced by reusing Oriental lily bulbs are mostly harvested and marketed from June to August, when the selling price of lily cut flowers is relatively low, the economic benefit is limited. In the past two years, the Gansu Provincial Flower Engineering Technology Research Center, in cooperation with Gansu Lintao County Meilan Flower Company and the Lintao County Seed Farm, has explored a

Causes of Secondary Growth in Potatoes and Control Methods
Nilka County has a narrow and long terrain with a cool climate, suitable for the growth of cold-loving crops. Potatoes have always been the dominant main crop in the area. Through years of in-depth investigation and research, technicians have identified the causes of secondary growth in potatoes and the corresponding solutions. I. Secondary growth in potatoes In early August 2003, in Village 5 of Nilka Town, 1.3 hectares of potatoes sown in late April had tubers that had swollen to the size of eggs, the buds on the new tubers sprouted, and small tubers the size of a thumb grew out, while the new tubers grew and aged, no longer continuing to expand.

Key Technical Points of Indoor Secondary Fermentation for Agaricus bisporus Production
The compost that has undergone outdoor pre-fermentation is moved indoors, and through artificial temperature and air control, the compost is sterilized and fermented under specific environmental conditions, further enhancing the specificity and selectivity of the compost, so that the compost is fermented into a substrate more suitable for mushroom growth. This process is called indoor secondary fermentation. (1) Principle: Secondary fermentation is a biochemical reaction process in which the activities of various types of thermophilic microorganisms promote changes in the physical and chemical properties of the compost. Secondary fermentation can be divided into two stages. Stage one: raise the pile temperature

Preparation method of secondary spawn and production spawn of straw mushroom
Secondary spawn is the spawn made by transferring primary spawn into secondary spawn substrate. Secondary spawn can be used directly as production spawn. Generally, secondary spawn is transferred to the same kind of substrate for expanded culture to become production spawn. Secondary spawn is generally placed in 750 ml mushroom bottles or plastic bags. (1) Preparation of substrate. Formula 1: rice straw 90%, bran (rice bran) 9%, gypsum powder 1%. The preparation method is to select golden-yellow, non-moldy dry rice straw, cut it into 3 cm lengths, soak it in clean water for about 12 hours to
