Dalbay and Turag valleys in

Mongolia

Introduction

Memory

Aim of Research To determine soil seed bank of two

valleys:

By habitat

By soil depth

By seed size

By method

Materials and methods

Study area

Field experiment

Transects

0-5 cm

5-10 cm

Laboratory experiment

Laboratory of Ecology

Department of NUM

Extraction method

Seedling emergence

method

Data analysis

One way ANOVA

Results

Part I. Seed extraction

Seed number by habitats

Part II. Seedling emergence

Comparison two methods

Seed extraction

Overestimate

Seedling emergence

Underestimate

Conclusion

The seed bank and a germination rate in

riparian zone is higher than other zones.

Seed bank in in 0-5 cm depth of soil higher

than below.

The seed bigger than 2mm is most

common

Seed germination rate is significantly differs

by soil depths.
