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...
متن کاملProteome Analysis of Poplar Seed Vigor
Seed vigor is a complex property that determines the seed's potential for rapid uniform emergence and subsequent growth. However, the mechanism for change in seed vigor is poorly understood. The seeds of poplar (Populus × Canadensis Moench), which are short-lived, were stored at 30 °C and 75 ± 5% relative humidity for different periods of time (0-90 days) to obtain different vigor seeds (from 9...
متن کاملRelevance of amadori and maillard products to seed deterioration.
The possible role of Amadori and Maillard reactions in the deterioration of dry seeds was investigated using model systems and whole soybean seeds, Glycine max cv Hodgson. In model systems of glucose plus an enzyme (lysozyme), the production of Amadori products was accelerated by higher temperature and relative humidity. The reaction between glucose and lysozyme at 50 degrees C, 75% relative hu...
متن کاملStudy 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...
