Meta-topolin [6-(3-hydroxybenzylamino)purine] is an aromatic cytokinin. It was first isolated from poplar leaves. Its name is derived from “topol”, the Czech word for poplar. The metabolism of meta-topolin is similar to that of other cytokinins. Just as zeatin and BAP, meta-topolin may undergo ribosylation at position 9 without a significant effect on the activity.The shoot production in media with BAP and meta-topolin is very similar, however, after transfer of the seedlings to soil, the shoots produced with meta-topolin produce better roots.


Uses & Benefits:

 1) Promoting growth, increasing yield, improving quality.

2) Increasing the percentage of fruit setting, promoting fruit’s enlarging.

3) Improving the ability of cold resistance and drought resistance.

4) Improving the ability of disease resistance.

5) Regulating differentiation in issue culture.

6) Efficiently relieve harmful effect of pesticide, fungicides, herbcides.

7) Increasing activity and energy of seeds and germination percentage.

2) Effectively prolong the duration time of natural preservation and transportation of fruits, vegetables and flowes when applied 5-10days before harvest.

Foliar spraying of Alginate oligosaccharides restores growth of wheat under chlorpyrifos stress

图片
    Chlorpyrifos, as an organophosphorus insecticide and acaricide, is suitable for the control of various chewing and sucking mouthparts pests such as wheat. However, excessive use will lead to changes in crop soluble proteins, glutathione-S-transferase, glutathione peroxidase, etc., resulting in pesticide stress, thereby affecting crop growth. In 2015, Zhang Shoudong, Northwest Institute of Plateau Biology, Chinese Academy of Sciences, etc. published an article "Effects of Alginate Oligosaccharides on Physiological and Biochemical Indexes of Wheat Seedlings Under Chlorpyrifos Stress". In this experiment, spraying 0.4% concentration of Alginate oligosaccharides significantly alleviated the decrease of chlorophyll content and wheat biomass in wheat seedlings under chlorpyrifos stress, inhibited the increase of proline, soluble protein and soluble sugar content, and enhanced wheat Resistance to chlorpyrifos stress. Test Results: (Note: CK: distilled water treatment, T0-T4: 0/0

How to prevent discoloration of tomato sepals

图片
Recently, many vegetable farmers have reported that the quality of tomato sepals are poor and turned brown, so that the fruit does not look bright, which affects the sales price, and many vegetable farmers have no remedy for this. There are four main reasons for the poor quality of tomato sepals. Vegetable farmers can take preventive measures. 1. Root injury is growing poorly Due to drought, waterlogging, excessive fertilization, etc., the roots are damaged, the plant growth is poor, and the plant's endogenous hormone synthesis is insufficient, which will cause the leaves to yellow and the sepals of the fruit will age and turn yellow-brown. This requires strengthening management, improving growth, and avoiding root-damaging factors. Suggest Irrigation with rooting agents to promote root recovery, foliar spray with 6000 times of sodium nitrophenolate and 1500 times of brassinolide plus 400 times of nucleotides to promote the green synthesis of tomato leaves and sepals. 2. High tempe

Analysis on the role of rhizobia in soybean planting

图片
Rhizobium soybean is a live microbial preparation. The rhizobia in the root nodules and the legumes are mutually beneficial: the organic matter produced by the legumes through photosynthesis is partly supplied to the rhizobia; the ammonia produced by the rhizobia through biological nitrogen fixation is supplied to the legumes plant. , it fixes free nitrogen in the air to supply soybeans to meet soybean demand for nitrogen. It is a good measure to increase soybean yield, save fertilizer and reduce pollution, and has been valued by researchers around the world. First, the role of rhizobia 1. Nitrogen fixation Soybean rhizobia uses the products of soybean photosynthesis as energy, and converts nitrogen in the air into nutrients required for soybean growth and development. Rhizobium and soybean have a symbiotic nitrogen fixation relationship. At the beginning, soybean rhizobia fixed little nitrogen, until flowering to drum. The initial stage of grain is the peak of nitrogen fixation by so
