Abstract: Daylily (Hemerocallis) is a perennial herbaceous plant widely used in landscape gardening. Daylilies are prized for their long term flowering mainly in late summer and low maintenance cultivation. According to flower spike height, the varieties are divided into runt, medium-growing and tall. The article contains the results of the study of 21 medium-growing daylily varieties’ terms of flowering in the botanic garden of the Volga region State University of Technology (Yoshkar-Ola, the Republic of Mari El). The research was conducted in 2015 - 2017. The calendar dates were converted into a continuous series. All varieties were classified as early, medium or late according to the terms of the beginning and the end of flowering and its duration. During three years of research, the earliest beginning of the phenological phase was registered in 2016, and the latest one  - in 2017. The early beginning and ending of flowering were typical for the varieties “Dr Regel” and “Royal Sovereign”. The late beginning of flowering was registered for the “Country Club” variety, and the late ending - for “Sandalwood”. Other varieties were classified as medium-term. The varieties “Royal Sovereign”, “Tejas”, and “Sugar Candy” are characterized by a short flowering period, while “Sandalwood” and “Derby Bound” - with a long one. It was established that the late-flowering varieties are characterized with a longer flowering period.

Kuznetsova I.N. - Minimization of damage at agriculture objects (vineyards) by using hunting birds of prey as bio-repellents pp. 7-13

Abstract: Wine-growers often face the necessity of fighting the insects, diseases, and pests threatening their business, and of protecting each racemation of their future harvest. Among the most frequent threats are the flocks of birds considering vineyards as a source of forage, which can eliminate the crop very fast. For many years, wine-growers have used various on-trend ways of repelling to avoid the destruction of harvest and plants, including the noisy air guns, laser emitters, holographic tapes, nets covering grapevines, acoustic systems, and even kites. However, the above mentioned means lose their effectiveness sooner or later, and their repelling effect lasts less than it is necessary for harvest ripening and preservation. It is explained by birds’ and animals’ adaptation to the changes in the environment - birds stop paying attention to the threats that haven’t been proved in reality or haven’t caused death. The forming adaptation leads to ignoring, birds and animals focus on foraging, and the harvest becomes at risk again. Meanwhile, the most significant results in harvest preservation are achieved by using a time-tested method of repelling, which doesn’t require any weird technologies - that is falconry. Based on a natural fear of a predator, the bio-repellent method doesn’t build up a tolerance. A centuries-old tradition of falconry is effective and fully in line with the current international standards in the field of environmentally safe products manufacturing.
