ABSTRACT.
A microbial survey carried out in seven fields of three grapevine nurseries
in the Jordan Valley showed significant differences in the viable count of
total bacteria between the fields within the same nursery and between
fields of different nurseries. Average Streptomyces counts however
were not significantly different. Viable counts for both total bacteria and
streptomycetes were mostly higher in spring and lower in autumn. No
significant correlation (P{ 0.05) was observed between viable bacterial and
Streptomyces counts and environmental conditions (temperature, pH,
soil moisture, total nitrogen content, phosphorus, potassium and soil
texture). Plant type, plant exudate, plant age and microbial interaction
may have accounted for the observed fluctuations.
