Problems solved by technology

[0003] At present, there are mainly two widely used methods for judging the strength of plant stems: one is based on the perception of the human body, and the strength is judged by the feeling of bending the stem by hand. There are differences, so the results of stem strength determination are quite different, and scientific and effective data cannot be obtained; the other is based on mechanics, using a stem strength tester for measurement, which mainly uses pressure sensors to detect the bending of stems This method is simple and convenient to implement, but the consistency of manual operation is very low, the reliability of the results is greatly affected, and the instrument has certain limitations on the measured stems, some young stems Stalk cannot show readings due to too low intensity

Abstract

A microcosmic identification method for the stem strength of cut peony flowers, comprising the following steps: (1) fixing the stems of cut flowers of peony: cutting the stems of cut flowers of peony and fixing them in pentylene glycol + paraformaldehyde solution; (2) adding (3) Observation of the thickness of the secondary cell wall thickened by the xylem; (4) Statistical analysis of the thickened cell layer and the thickness of the secondary cell wall of the xylem secondary wall of the peony cut flower stalk, through which Two indicators were used to identify the stem strength of peony cut flowers. The method adopted in the present invention can be directly observed and identified according to the microstructure, is convenient and simple, has no interference from human factors, and has low error; and is not limited by time, the sample can be preserved and observed for a long time, and repeated measurements can be made, and the method has high feasibility.

Description

technical field [0001] The invention relates to a microcosmic identification method for the stem strength of peony cut flowers, and belongs to the technical field of peony stem strength detection methods. Background technique [0002] Paeonia lactiflora (Paeonia lactiflora Pall.) is one of the top ten traditional famous flowers in my country. In ancient times, there is a famous saying "Paeonia lactiflora is the favorite of spring, never envy peony" to praise the beauty of peony. In recent years, peony has become a high-end product in the flower market, and the supply exceeds demand in the international cut flower market (Sun Jing, 2018). Stem erection is an important quality indicator in most cut flower production. For example, in the production of cut gerbera flowers, large and heavy inflorescences and thin flower stems often lead to the phenomenon of "bent neck" in flower stems. Similar problems also occur in the production of peony cut flowers. The flower stems of some ...
