Evaluation of the yield of wrinkled rosehip (Rosa rugosa Thunb.) in conditions of the south of Primorsky krai

Abstract

The article studies the yield of wrinkled rosehip (Rosa rugosa Thunb.). This species is the most promising for industrial breeding in the Far East. The studies were carried out on three plots on different types of soils. Measurements of such indicators as: density, height, age, number and weight of fruits, followed by analysis of the results are obtained. The dependence of the number of rosehip fruits on age has been revealed. Habitat conditions affect the number of stems. The results have shown that the number of stems (density) in curtains is much less than in continuous thickets, therefore, the yield here is smaller. According to the data obtained, the height of rosehip thickets belongs to the 1st productivity class with an average height of 1.6 m and 1.28 m, respectively. According to the data obtained, the most fruit-bearing age is 5 years. From the studies obtained, it was revealed that approximately 7.57 fruits per m2 grow in sandy mane conditions, and twice as many ‒ 16.93 fruits per m2 ‒ on meadow soils. The yield of dry weight of rosehip in relation to raw weight ranges from 37.66 % to 38.30 %.
