Physiological Alterations and Nondestructive Test Methods of Crop Seed Vigor: A Comprehensive Review
نویسندگان
چکیده
Seed vigor is one of the essential contents agricultural research. The decline seed described as an inevitable process. Recent studies have shown that oxidative damage caused by reactive oxygen species (ROS) main reason for destruction various chemicals in seeds and eventually evolves into death. traditional tests, such germination test TTC staining, are commonly used to assess vigor. However, these methods often need a large number experimental samples, which will bring waste resources. At present, many new fast nondestructive seeds, vibrational spectroscopic techniques, been achieved convincing results. This paper aimed at analyzing microchanges seed-vigor decline, summarizing performance current methods, hoping provide idea testing single combining physiological alterations with chemometrics algorithms.

Seed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
متن کاملStandardization of Seed Vigor Tests
The last 30 years have led to increasing dissatisfaction by seed producers and consumers with the standard germination test as the sole criterion of seed performance potential presented on a seed label. As a result, new seed testing techniques have been formulated known as seed vigor tests that provide more sensitive measures of seed quality. The ISTA and AOSA Vigor Test Committees have been at...

Study on some aspects of seed viability and vigor
Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...
