ABSTRACT

The area of Sombor occupies the northwest part of Bačka Plateau. The examined area is mostly an agricultural land, the rest are wood-steppe type and swamps.

On this terrain, 645 wild-growing plants have been described. Among them, we've found 53 poisonous. These are the plants of the almost infrequent Yellow Pheasant's Eye (Adonis vernalis), through gorgeous Yellow Iris (Iris pseudacorus) up to everywhere present Thorn-apple (Datura stramonium). We've found poisonous plants of 30 families. The most numerous, 11 of them, belong to Buttercup Family (Ranunculaceae). Each plant we've termed in Latin and English. Besides, a short description of habitation, poisonous parts of plant, content of toxic substances and related symptoms of intoxication are presented too. The enclosed original photos show the typical terrain around Sombor and some of founded poisonous plants.

The encouraging fact is that in the area where 90,7% of land is agricultural still such a number of wild-growing plants can be find. In this investigation, we've paid attention only to poisonous wild-growing plants.

Key words: poisonous plants, poisonous parts of plants, toxic plant's origin substances, symptoms of plant intoxication.


INTRODUCTION

Sombor with its surroundings is a plain and slightly uneven land with the height of 82-83 m above sea level. The land is intersected by canals, embankments and swamps. The climate is moderate-continental, with annual precipitation of 590 mm and the average annual temperature of 11°C.

The examined area, 1.178 km2, is mostly an agricultural land, the rest are wood-steppe type and swamps. On this terrain 645 wild-growing plants have been described. In this investigation we've paid attention only to poisonous plants.


RESULTS

Among wild-growing plants of Sombor's surroundings, we've found 53 poisonous. Owing to better review, founded poisonous plants are grouped in Latin families, in alphabetical order.

DISCUSSION

In analyzing of habitations on which particular species of poisonous wild-growing plants are presented on examined terrain, we can notice that: most of them, 17 spec. belong to woods and scrubs, 12 spec. are on waste places, 11 spec. on grassy places, 6 spec. on arable fields, 5 spec. in swamps and wet places, 2 spec. on sandy soils.


CONCLUSION

Message is evident: poisonous wild-growing plants are draggling on places where mankind influence is smaller (woods and scrubs waste places). On the other hand, there are less and less swamps and wet places, just as uncultivated sandy soils, consequently a small number of plants asked such conditions.

The encouraging fact is that in the area where 90,7% of land is agricultural, still such a number of wild-growing plants can be find.

By ecological point of view, existence of wild-growing plants with active substances is of great importance (especially nowadays).
