A comparative anatomical study of aneurolepidium chinense (trin.)‎ Kitag. From different ecological environments

الملخص EN

The anatomy and structure of roots, stems and leaves from Aneurolepidium Chinese (Trin.) Kitbag.

Plants grown under different ecological environments were studied using scanning electron microscopy in this paper.

The results showed that conspicuous diversities in this anatomical and histological structure existed in different ecological variants of this species.

The structure of A.

Chinese in black calcium soil’s structure is simple type.

The saline meadow soil type’s structure is complex, which have evolved the evolutional tissues (Gu et al., 1993), i.e.

parenchyma, protective tissue parenchyma and conducting tissue etc.

The results of this study showed that there are the most striking differences in the same species of A.

Chinese of different soil types.

These differences indicated that different soil ecotypes of A.

Chinese can exist in natural conditions.

A.

Chinese is a species widely distributed in grassland in the west part of northeast China and the east part of Inner Mongolia (Li De-xin, 1979 ; Jiandong, 1964 and 1978 ; Yun-fei and Bao-tian, 1992).

It usually forms the predominant population in grassland known as the Aneurolepidium grassland.

This plant is an excellent herbage species with a high nutritional value and good suitability for animal feeding.

It is also tolerant of high saline soil drought and trampling.

The objective of this investigation was to elucidate its anatomical characteristics in its adaptation to saline environment (Cheng-lee, 1981).

Observations were made comparing the anatomy of two C3 plants in ecological variants.

The results obtained through this investigation provide a basis for future studying the biological and ecological characteristics of this important herbage species.
