The application discloses a kind of plant petal segmentation methods based on point cloud, belong to the field of forestry technology, for many petal flat type plant flower, first extract the three-dimensional point cloud data of plant flower;According to the three-dimensional point cloud data of plant flower, the coordinates of point in point cloud are calculated, the approximate longitude and latitude of flower main shaft are determined, and the main shaft of flower point cloud is rotated to coincide with Y axis;Then according to the direction of flower main shaft, the rectangular coordinates of flower point cloud are transformed into cylindrical coordinates;According to the transformed flower point cloud coordinates, the bottom of flower is segmented, the position of petal is determined, and finally the boundary of petal is segmented, to obtain the petal after segmentation.The method can quickly segment the petal in flower, without a large amount of point cloud data, and the segmentation precision is high.

The economic loss of discarded flowering plants (waste flowers) is a problem, and there is a need for effective utilization of petals. The purpose of this disclosure is to provide a method for producing biomembrane microparticles from plant petals, biomembrane microparticles obtained by this method, and raw materials for cosmetic compositions and cosmetic compositions containing said biomembrane microparticles. [Solution] A method for producing biomembrane microparticles derived from plant petals, comprising the steps of: (a) obtaining a petal extract from petals, and (b) purifying the petal extract to obtain biomembrane microparticles.

This invention provides cotton GoYP The application of genes in regulating plant petal size and / or petal color belongs to the field of genetic engineering technology. In this invention, GoYP Genes include GhYP Genes and / or GaYP Genes; among which, GhYP Genes can regulate the biosynthesis of flavonoids (anthocyanins and / or flavonols) in plant petals and promote petal elongation by promoting the biosynthesis of brassinosteroids (BRs). GhYP This gene encodes the R2R3-MYB regulatory factor, which has a dual function of promoting the biosynthesis of flavonoids and BRs, providing a new gene resource and a more convenient method for the synergistic improvement of the color and size of ornamental plant petals. Simultaneously, through petal-specific expression promoters... proGaFLS Driver genes GaYP Overexpression of the gene in tobacco petals resulted in redder and larger petals, further demonstrating the gene's efficacy. GoYP Its application value.
