Persimmon's culture as a fruit plant has been known in Ukraine since the last century,
now it is represented by three deciduous species (Caucasian, Virgin, Oriental), as well as hybrids
of persimmon and Oriental, which give edible fruit and are widely used in southern and
subtropical horticulture.
The introduction of new plant species in combination with an integrated system of
agricultural technology will make it possible to minimize the use of pesticides and obtain
environmentally friendly products.
Delicious and nutritious persimmon fruits are rich in vitamins and polyphenolic
substances, carotenoids, as well as organic compounds of potassium, iron, and calcium.
Distinctive and very useful quality of persimmon fruit – high iodine content and low acidity.
Fresh fruit pulp contains 13 organic acids, including citric, malic, carotene, dyes, and tannins,
25 macro-and micronutrients, nine of which are essential for the human body. Among them Cu,
Zn, Mn, Mo.
The purpose of our work is to assess the success of the introduction and adaptation, to
establish the prospects for the cultivation of persimmons (Diospyros L.) in the south of Ukraine.
The material of our research was the varietal diversity of persimmons, which originates
from three countries (Japan, Georgia, and the USA), as well as obtained as a result of selection
work in Ukraine, in the collection plantations of the State Enterprise "Research Farm
Novokakhovske "Rice Institute NAAS ".
The experience of growing Diospyros outside the southern coast of Crimea shows that the
weather and climatic conditions of the Kherson region are fully consistent with their biological
characteristics and they, with proper farming techniques, are suitable for cultivation in
backyards, cottages, amateur and farm gardens.
Years of research have shown that persimmon plants in the Kherson region during the
growing season go through all stages of seasonal development and tie the fruit, which fully
ripens and gives similar seeds.
Studies of the biological characteristics of persimmons have been conducted since 1999,
its collection was formed on the farm with the support of the NBS-NSC since the late 1980 s.
Today in the collection of SE "DG" Novokakhovske" and Rice NAAS" there are about 60 samples.
Most of which are samples that were obtained by us as a result of selection work. They show
much higher winter hardiness than cultivars Diospyros kaki L., can withstand temperatures
down to -20–25 °C.
According to the results of many years of research, for the first time in Ukraine we have
registered in the National Center for Plant Genetic Resources of Ukraine a Designable Collection
of Persimmons based on distinction, samples are presented here by three countries of the
world: Japan, Georgia, the USA, and also, received as a result of selection work in Ukraine,
including own.
Keywords: Diospyros, fruits, cultivars, collection.
