Description

A corn seed germination root system observation germination device

technical field

The utility model relates to a corn seed germination device, in particular to a corn seed germination root system observation germination device. The utility model is mainly used for the observation of the root system of seed germination and the determination of related seed vigor indexes, and belongs to the field of seed science and technology.

Background technique

Seed germination test is an important part of related scientific research work such as seed inspection, and it is of great significance in the aspects of seed biology research, seed quality management, realization of improved varieties and standardization of seed quality.

The root system is the foundation of corn growth, and a strong root system provides sufficient nutrients and water for the growth and development of corn. The determination of root morphological and physiological indicators in the germination stage of maize seeds is an important part of evaluating seed vigor, which can effectively predict the ability of seed germination to form strong seedlings and directly or indirectly affect the yield and quality of maize plants. In addition, it can also be used in the study of the formation mechanism of high vigor of corn seeds and the selection and breeding of high vigor corn varieties.

At present, the germination methods commonly used in corn seed germination tests are between paper germination and sand germination. From the perspective of observation and analysis of corn seed germination and root system related vitality indicators, the existing roll paper germination and the germination of the fixed substrate germination using the germination box are both in the later stage of corn seed germination. (Seedling stage) There are deficiencies in the observation of larger root system indicators, which are mainly due to the lack of space for root system growth and the inconvenience of taking out and separating. In order to obtain correct evaluation results of seed vigor, especially root system-related indicators, it is necessary to continuously innovate and improve germination vessels according to the actual needs of seed germination and root system observation.

In the existing market, there is no relevant professional germination device for maize seed germination, especially for root observation in the later stage of germination.

Therefore, in view of the problems existing in the observation of corn seed germination root system and the needs of relevant teaching and scientific research work, a simple and practical corn seed germination root system observation and germination device has been developed. The advantages of large growth space, convenient root system observation, consistent germination environment, convenient operation, high work efficiency, and wide application range are of great practical significance for accurately evaluating the relative vitality indicators of maize seed germination root system and carrying out related scientific research work.
