| Popis: | Nowadays, ornamental grasses are an obligatory component of urban green landscapes. Introduced species such as Miscanthus giganteus, a sterile triploid hybrid from the grass family, play a major role. However, under natural conditions, Miscanthus giganteus requires an average annual air temperature of +5°C to +10°C and rainfall of at least 700 mm. Penza region belongs to the zone of unstable moisture. Therefore, there was a need to determine the adaptability of Miscanthus giganteus and justify its use in landscape architecture. The planting was carried out in May 2013 by seedling method and in the open ground by rootstocks in the scheme 100 × 50 cm at the collection site of Penza State Agrarian University on light gray soil. The plants grown from seedlings proved to be stress-tolerant and in mid-July were 95 cm in height and 90 cm - grown in the open ground with a main stem thickness of 13 mm. During the winter months of 2014, both low negative temperatures and positive temperatures with insufficient snow cover were observed. However, Miscanthus overwintered well and there was no soaking or drying out of the plants in spring. The second-third, sixth-seventh years of miscanthus life were characterized by unstable moisture with HTC - 0.60-0.87, sufficient and excessive (1.27...1.60) in 2016, 2017, 2020 and 2021. Spring regrowth in the first years was observed until mid-May, in the last three years at the end of the month. Stem density varied from 74 to 196 pcs/m2, plant height was 2.20...3.85 m with stem diameter of 10...15 mm. While the stems are of different quality, they are highly decorative because of their dark cherry-colored and weeping leaves with white central veins. Therefore, it can be widely used in landscape phytodesign of gardens and parks, for decorating the banks of reservoirs and in landscape flower beds. |
