TECHNOLOGICAL ASPECTS OF GROWING SEEDLINGS OF SYCAMORE MAPLE IN THE DRY CLIMATE OF ROSTOV REGION

In the conditions of the dry steppe temperature increase has in the spring the avalanche character, sharply reducing stocks of productive moisture in the soil in this connection, in the conditions of an open ground of forest and decorative nurseries it is necessary to create conditions for fast and amicable germination of seeds at the very beginning of the vegetative period. For this purpose various growth factors of plants are most often used.
During 2011 - 2012 we conducted researches on studying of influence of preseeding processing by the physiologically active agents (PAA) of seeds of a sycamore maple in field conditions. As seeds of a maple possess deep endogenous rest, before crops they were killed during 24 h in PAA solutions: krezatcinа in concentration of 0,001%, 0,002%, 0,003%; Humate + – 0,01%, 0,02%, 0,03%; as control dry seeds and killed in water served.
The received results testify that preliminary soaking of seeds of a sycamore maple in solution of physiologically active agents makes positive impact on change of biometric parameters of seedlings. However it is necessary to consider that plants need sufficient moisture providing.
