Abstract

In the garden of Omsk Agrarian Scientific Center, located in the southern forest-steppe of Omsk region in 2018-2020 research has been carried out with the aim of studying the features of the influence of various stimulants of root formation during the propagation of clonal pear rootstocks by green and lignified cuttings. The soil is meadow-chernozemic medium loamy with a pronounced sandy fraction, the reaction of the soil solution is close to neutral. The object of research is clonal pear stocks PG 2, PG 12, PG 17-16. Rooting of green and lignified cuttings was carried out in a greenhouse with a film coating with an artificial fogging installation. The substrate is a mixture of sand and peat (1 to 1). Planting scheme of cuttings 5×5 cm, in four replicates (50 pcs.), Placement is randomized. Kornevin (powdering of sections), and Ribav-extra, control – water (duration of exposure - 16 h) were used as stimulants of root formation during green cuttings. When propagating by lignified cuttings, cornevin (0,1%) and ribav-extra (0,01%) were used; water was used as control (exposure duration - 16 h). Clonal pear rootstocks tolerated the winter conditions of the study years relatively favorably. The exception was winter 2019-2020, the total degree of freezing was 1 point in the PG 2 and PG 17-16 rootstocks, and 5 points in the PG 12 rootstock (90% plant loss). The beginning of the growing season in 2018 was marked on May 22-23, in 2019 - May 5-6, in 2020 - April 18-19. In 2018-2019, green cuttings were carried out on June 20, in 2020 - on June 10. Earlier terms of cuttings in 2020 are explained by the rapid regrowth and lignification of the shoots (hot weather and lack of precipitation in the first months of the growing season). In the control, massive root formation was noted after 6 weeks. The treatment of cuttings with growth stimulants promoted the acceleration of root formation, which was observed after 4 ... 5 weeks. On average, over the years of research, rooting rate when using Kornevin, in comparison with control, increased by 13 ... 18%, Ribav -extra - by 10 ... 13%. The rootstock PG 12 is characterized by a higher rooting Kornevin of green cuttings (51.5 ... 56.5%) than that of PG 2 (47.7 ... 49%) and PG 17-16 (41.7 ... 44.3%). Rooting rate when using Kornevin was 50%, Ribav - extra 47%. PG 12 is the only rootstock under study in which rooting of lignified cuttings is observed: in the control 24%, when using preparations 44.5 ... 52%
