Annotation

Considerable influence on rizogenesis of green cuttings, biometric indicators and quality of a landing material of fruit crops exerts a soil substratum. For process of rooting the methods of preparation of cuttings material have essential value also. Prelanding processing of cuttings in the solutions of growth regulators improves the rooting and quality of a landing material. The purpose of our work is research of influence of substratum and growth regulators on rooting of sea-buckthorn cuttings taking into account its varietal features. There are three varieties of a sea-buckthorn in the experience � Businka, Zolotistaya and Chuyskaya. Landing of cuttings is carried out in the first decade of July. The nutritious mixes received on a basis of local raw materials � sapropel, peat and lignin are researched. Green cuttings is carried out by the standard technique. It is established that the activity of rizogenesis and biometric parameters of sea-buckthorn cuttings depends on the varietal features, used substratum and applied growth regulators. The analysis of results of experience showed that the share of influence of growth regulators on quantity of standard landing material of sea-buckthorn is 55,2%, a substratum share is 42%, a share of varietal reactions of a sea-buckthorn�s plants is 2,8%. The most positive effect of impact on quality of a landing material of a sea-buckthorn is obtained on a substratum �peat+sand+lignin+soil�. On interaction "variety � growth stimulator" the following combinations were more productively: Zolotistaya-IMK, Chuyskaya-IUK.
