35 Incidence of storage fungi and hydropriming on soybean seeds1 Denis Santiago da Costa2*, Nathalie Bonassa3, Ana Dionisia da Luz Coelho Novembre2 ABSTRACT – Priming is a technique applicable to seeds of various plant species; however, for soybean seed there is little available information correlating such technique to the storage fungi. Seed vigor. The concept of seed vigor is more difficult to describe than seed viability, but is equally as important for establishing seedlings in the field or greenhouse. Research in this area has established the importance of seed vigor on stand establishment and has begun to elucidate some of the underlying mechanisms for seed vigor.

Although seed vigor is a complex concept, a widely accepted definition is “the sum of all those properties which determine the potential for rapid, uniform emergence, and development of normal seedlings under a wide range of field conditions” (Baalbaki et al., 2009). Field emergence and several seed vigor tests were used to evaluate the quality of different canola seed lots. Four seed lots representing two winter and two spring cultivars were aged at 42 degrees C at various time intervals to provide six sub-lots with a range of seed vigor.

Seed germination and emergence is the first step for successful production of most plants. The ability of seeds to germinate (often called viability) and to emerge in soil is the key for plant establishment. Seed testing is commonly used to assess viability (the ability to germinate under ideal conditions) and vigor (the ability to emerge in soil under stress conditions), and to determine the These standards have been developed for parties that have a working knowledge of seed testing and are familiar with seed testing materials, instruments and equipment .
