The invention discloses an induction method of poplar tetraploid plants, belonging to the field of plant inheritance breeding. The method of the invention comprises the following steps: pollination is carried out on female inflorescence of poplar female parent by powder of poplar male parent to form infructescence, when flocculent fiber is formed and wraps ovule in the infructescence ovary, physicochemical treatment is carried out on the infructescence, seed selection is carried out on tetraploid plants; the inventor of the invention discovers by tests that the effective period for carrying out physicochemical treatment to induce the zygote chromosome to be reduplicated is when most zygotes of the poplar is at the first mitosis process and the flocculent fiber starts to wrap but does not completely covet the ovule, thus the induction efficiency of tetraploid plants is improved. The invention avoids verbose links such as fixing, dehydrating, waxing, embedding, slicing, pigmentation, microexamination of the ovule and the like, thus enhancing the timeliness of physicochemical treatment, saving induction reagent and experimental material and improving the precision and stability of the reduplication of zygote chromosome.

The invention discloses a simple method for preparing porous carbon spheres from ripe fruits (capitate infructescence) of Liquidambar formosana hance. The porous carbon spheres with certain mechanical strength can be obtained through a simple charring process by using the method. The carbon spheres keep the spherical structure and the tunnel structure of original fruit spheres, have extremely strong lipophilic and hydrophobic properties, can float on the water surface, and can rapidly adsorb various oils and organic solvents on the water surface. The carbon spheres have excellent desorption performance (reaching 99%) and cycle use performances. Raw materials of the above product are abundant and cheap, the preparation method is concise, and the product has high oil or organic matter adsorption performance, so the carbon spheres are a functionalized material having extremely good prospect and being used for adsorbing and recovering oil stains and organic solvents on water.

The invention discloses a perfoliote knotweed herb planting method, which comprises the following steps: when persistent tapels on the spicate infructescences of perfoliote knotweed herbs become blue and the seeds are black, harvesting the seeds; placing the seeds into a basin, removing the persistent blue tapels of fruits through rubbing, and drying; putting the obtained products in storage, wherein the storage conditions are as follows: the temperature is 0-5 DEG C, and the humidity is 20-60%; placing the seeds into a basin filled with warm water at a temperature of 30-35 DEG C, after the seeds are soaked for 24 h, drying the seeds, thoroughly watering a seedbed firstly, casting the seeds in a proportion of 100-150 grains / m<2>, and uniformly covering the seeds at a depth of 1-2 cm by using fine soil; selecting a rainy day, digging well-grown perfoliote knotweed herb seedlings with soil from the seedbed, and planting the seedlings in cultivated fields according to a planting space of 50cm*50cm; carrying out field management; and harvesting. Perfoliote knotweed herbs obtained by using the method disclosed by the invention are stable in quality, less in planting investment and high in benefits, and can promote local economic development.

The invention discloses a method for improving soapberry infructescence fruit setting by utilizing exogenous substances. The method comprises the steps: spraying a spermine-containing solution, a spermidine-containing solution or a mixed solution of spermine and spermidine in a flowering phase of the soapberry. By spraying the spermidine and spermine of different concentrations in the flowering phase, the soapberry infructescence fruit setting can be obviously improved, internal content is possibly increased due to spraying and absorption of the spermidine and spermine, and losses caused by anobvious decrease of polyamine content in fruit development after the flowering phase are effectively supplemented. Therefore, the infructescence fruit setting number is improved to a certain degree.

The invention discloses photinia serrulata procyanidine as well as a preparation method and an application thereof. The photinia serrulata procyanidine is prepared by extracting and purifying rachis of a photinia plant as an effective component. According to the photinia serrulata procyanidine as well as the preparation method and application, the branches, leaves and fruits of the photinia plant contain extremely high procyanidine like substances, and the matured rachis contain the most procyanidine; the plant extractive prepared through the rachis of the photinia plant by purifying has the antioxidant activity under low concentration higher than that as specified in the specification under the same mass concentration; and the chemical component analysis sheet shows that the contents of flavonoid components, phenol components and symbolic flavane-3-alcohol antioxidant components in the extractive are higher than that as specified in the specification. The raw materials of the extractive are easily obtained, the extracting process is simple, the cost is small, and wide market prospect and high economic value are brought.
