Фенологические особенности сортов роз при выращивании в условиях защищенного грунта

Abstract

The results of studies on the phenological characteristics of five cultivars of cut roses (Chiri, Grand Prix, Gratsia, Jumilia, Red Naomi) when grown in low-volume culture in the Moscow region are presented. Jumilia with folded leaves has the greatest potential for budding (7 days), the highest shoot growth activity and early entry into the phase of mass growth of stems and leaves (14 days). Red Naomi in the middle of the row has low bud awakening (14 days), the least shoot growth activity and late entry into the phase of mass regrowth of stems and leaves (21 days). Jumilia, regardless of its location in the greenhouse, and Chiri at the beginning of the row and in the variant with a folded leaf are characterized by faster bud formation (39–41 days). Gratsia and Red Naomi in the middle of the row are characterized by slower bud formation (47–48 days). Jumilia in the folded leaf varieties and at the beginning of the row is distinguished by the earliest entry into the commercial phase (49–50 days). Gratsia and Red Naomi in the middlerow variety (60–62 days) are characterised by long peduncle formation. The longest peduncle at the time of cutting was observed in Gratsia (90,4–95,1 cm) and Jumilia (86,2–90,2 cm). Chiri has the shortest stem (65,4–70,3 cm).
