Described is a method for vegetative propagation of plants by exposing a plant material to an oxytocin solution and / or a variant and / or derivative thereof.

The invention belongs to the field of cell engineering seedling culture of algae, and particularly relates to a cell engineering seedling culture method of gracilaria lemaneiformis. The gracilaria lemaneiformis frond is constructed into a miniaturized form, and high-density intensive culture is carried out by utilizing a photobioreactor. According to the method, the microminiaturized asparagus frond obtained by a cell engineering means can be subjected to vegetative propagation, efficient propagation is carried out by utilizing the algae photobioreactor, and the microminiaturized asparagus frond is further cultured into seedlings for artificial cultivation.

The present invention discloses a method for constructing a sargassum field based on rhizoid vegetative propagation, comprising the following steps: (1) fabricating artificial reefs and, during the vigorous growth period of sargassum, placing the artificial reefs in a natural sargassum field serving as a cultivation sea area for soaking; (2) after soaking the artificial reefs for 1 month, performing a treatment of cutting off the receptacles on the natural sargassum in the cultivation sea area; arranging the soaked artificial reefs around the rhizoids of the sargassum with the receptacles cut off, keeping them close to the rhizoids; (3) cultivating the artificial reefs in the cultivation sea area to enable the rhizoids of sargassum to attach to the surface of the artificial reefs and grow, and regenerating new seedlings through vegetative propagation; when the coverage of the rhizoids of sargassum on the upper surface of the artificial reefs is similar to the coverage of the rhizoids of natural sargassum, transplanting the artificial reefs to the target restoration sea area. This method can enable the rhizoids of sargassum to attach to and grow on the artificial reefs, and ensure the stable reproduction of the sargassum population in the target restoration sea area.

The present invention provides a method and application for propagating seedlings of Amorphophallus konjac, belonging to the technical field of plant vegetative propagation. The present invention provides a method for propagating seedlings of Amorphophallus konjac, comprising: picking out propagules from the middle and upper part of the underground corm of Amorphophallus konjac, and planting the picked out propagules and / or the underground corm after picking out the propagules; the diameter of the propagules is ≥1.5 cm, and the propagules do not include the main buds when picking out the propagules. The method for propagating seedlings of Amorphophallus konjac provided by the present invention is based on the characteristics of strong germination ability of the epidermis in the middle and upper part of the underground corm of Amorphophallus konjac, and can arbitrarily pick out propagules with skin and flesh in the middle and upper part of the underground corm. Not only can a single corm be used to pick out a large number of propagules with a high survival rate, but the original underground corm can also continue to be planted as seed taro in the same year.

A method of revegetating a native plant community such as a forest includes the steps of mechanically collecting forest floor material, specifically targeting native plant seeds, spores, and acrotelm layers, to restore native forest species. The collected material is formed into small pieces, such as pucks, for distribution on the target land. The pieces are formed by wetting the material with water and a binder as a wetting agent, mechanically compressed and dried to a moisture content less than 15% by volume. Each piece has a surface area of less than 25 sq cms and a thickness of less than 1.5 cms so that the pieces are smaller than the smallest length required for a root to emerge into a new plant. The process ensures that the material cannot dry out as the vegetative propagules die if it does. The material is formed into the pieces without being stockpiled or previously stored and without freezing.

Described is a method for stimulating vegetative propagation of a potato tuber by exposing a potato tuber to an composition comprising oxytocin and / or a fragment and / or variant of oxytocin possessing oxytocin activity, wherein the exposure of the oxytocin and / or said fragment and / or variant of oxytocin possessing oxytocin activity stimulates the formation and / or growth of at least one potato tuber.

The present invention provides a transgenic plant having enhanced stress resistance and / or a change in flower color, preferably a blue flower color, or a self-fertilized or filial generation thereof, or a part of a plant body, a tissue or a cell thereof, and provides a method for producing a flavone C-glycoside in a simple and efficient manner. The present invention uses a polynucleotide encoding an enzyme having dehydration activity for a 2-hydroxyflavanone C-glycoside.
