英文摘要 | Due to significant decreases in precipitation in northern China, knowledge of the response of seed germination and plant growth characteristics to key limiting factors is essential for vegetation restoration. We examined seed germination under different temperatures and water potentials, and we examined seedling growth under different amounts of water supply. Experiments were carried out in automatic temperature-, humidity-, and light-controlled growth chambers. Under low water potentials, the final germination percentages of four herbaceous species were high, while seed germination of the shrub species Caragana microphylla was significantly inhibited. Under the different water supply amounts, seedlings of Agropyron cristatum allocated more biomass to the root and had a higher growth rate than those of Elymus dahuricus and C.microphylla. In light of these results and drier environmental conditions (annual mean precipitation is 366mm, which falling mainly between June and August), potential selections for revegetation of different landscapes include the following: A.cristatum for shifting sand dunes, the establishment of the pioneer species Agriophyllum squarrosum, C.microphylla for semifixed sand dunes, E.dahuricus for fixed sand dunes, and Melilotus suaveolens and Medicago sativa for cultivation. |
