32. Beta-glucan content of oat grain grown in South Bulgaria. II. Effect of Humustim and Imunocitofit on β-glucan content of winter- and spring-grown oat cultivars

The effect of two growth regulators – Humustim and Imunocitofit on β-glucan content of four winter- and five spring-grown oat cultivars in South Bulgaria throughout the period 2006-2009 was studied. Results show stronger effect of Imunocitofit, which increased β-glucan content by 9.1% on average for the period and for all winter-grown cultivars, while the application of Humustim brought to an increase of 3.3%. However, it was found that β-glucan content of the spring-grown cultivars was positively affected only by Humustim.
Significant differences were found for the main effects of year, oat cultivars, growth regulators (Humustim and Imunocitofit) and their interaction.
