The treatment of the seeds with the phenolic compounds viz catechol, gallic acid and pyrogallic acid significantly decreased the germination percentage (Table 1). At 24 h stage of sampling, germination was observed only in the control plants. However, at 48 h and 72 h, a concomitant decrease in % germination with increasing. Spores of various Bacillus and Clostridium species are among the most resistant life forms known. Since the spores of some species are causative agents of much food spoilage, food poisoning, and human disease, and the spores of Bacillus anthracis are a major bioweapon, there is much interest in the mechanisms of spore resistance and how these spores can be by: Low light levels stimulated seeds of Helianthus paradoxus to germinate (Fig. 4). There was a significant differences between the light and dark treatments (F=, P=). Germination was 38 [+ or -] 10% in low light and 10 [+ or -] 5% in the dark. Gibberellic acid treatment also stimulated seeds of Helianthus paradoxus to germinate (Fig. 5).

Germination tests immediately followed treatments to evaluate effects of chemical stimulants on germination. Observations recorded were: 1-first germination count at 7 days after planting (DAP); 2-final germination count at 14 days after planting. This effect of high dry heat treatment of three accessions of Corchorus olitorious seeds on seed germination, seedling emergence and seedling vigour was evaluated in the laboratory and horticultural nursery of the School of Agriculture and Industrial Technology, Babcock University Size: KB.
The effect of fires in the 1st postfire growing season was to decrease height and basal area of alkali sacaton while stimulating growth of other grasses and forbs.
Summer fires had a more pronounced effect on alkali sacaton than winter fires [ 11, 93, 94 ]. ture stress on germination of several grass species. The effect of different levels of moisture tension on the germination of alkali sacaton, galleta, and blue grama apparently has not been investigated.
Methods and Materials Seeds used in the study were collected within theCited by: Abstract. The normal system functioning in the utilization of metabolizable germinants by both heat-sensitive and heat-resistant spores of Clostridium perfringens was inactivated by heat or by treatment of the spores with alkali to remove a soluble coat protein layer.
Altered spores were incapable of germination (less than 1%) and outgrowth (less than %) in complex media without the Cited by: only dry-heat exposure experiments (cases using scarification with boiling water were not include d) and only those in which the temper-atures applied were ≥ 50 ° C.
For each study and species, we compiled the percent germination of the control and the percent germination of each heat treatment (combination of temperature and exposure time). To monitor the effect of a germination step prior to a CIP procedure we simulated the first stage of the CIP procedure in the lab.
