| responses of caragana korshinskii to different aboveground shoot removal: combining defence and tolerance strategies. | it is generally assumed that plants respond to natural enemies by either allocating resources to resistance traits or compensating for damage. this study evaluated how different methods of artificial shoot removal influence two alternative strategies (i.e. tolerance and defence) of caragana korshinskii in the semi-arid area of china. | 2006 | 16687428 |
| effects of burial in sand and water supply regime on seedling emergence of six species. | air seeding has long been regarded as a quick and successful measure for vegetation rehabilitation in china. however, seedling emergence of often-used species including agriophyllum squarrosum, artemisia sphaerocephala, artemisia ordosica, hedysarum fruticosum, caragana korshinskii and medicago sativa is low. experiments were conducted under controlled conditions to study the effects of sowing depth and water supply on seedling emergence, in order to understand the requirements for increasing se ... | 2005 | 15820988 |
| [a comparative study on water use characteristics and eco-adaptability of hippophae rhamnoides and caragana korshinskii in semi-arid loess hilly-gully region]. | this study compared the seasonal dynamics of soil water content, biomass productivity, and leaf photosynthetic physiology and water potential between about ten years old hippophae rhamnoides and caragana korshinskii planted on the hilly slope land of semi-arid loess hilly-gully region. the results showed that there existed dry soil layer in the stands. the seasonal compensation depth of soil water in hippophae rhamnoides stand was deeper and its water use capability was better than those of c. k ... | 2004 | 15707306 |
| [succession pattern of artificial vegetation community and its ecological mechanism in an arid desert region]. | focusing on the artificial vegetation protection system of the shapotou section of baotou-lanzhou railway in the arid desert region of china, this paper examined the dynamics of dominant plant species and the succession pattern of artificial plant community in the process of establishing and developing regional artificial vegetation. it also studied the driving force and the ecologically intrinsic mechanism of the community succession. the results demonstrated that the species composition of the ... | 2003 | 14732997 |
| [response of seed germination of three xeromorphic shrubs to drought stress]. | the seed germination, seedling growth and water absorption characteristic of caragana korshinskii, hedysarum scoparium, and artemisia sphearocephala were investigated under different osmotic potentials (peg 6000, -0.3(-) -2.7 mpa). the results showed that under drought stress, c. korshinskii had the highest germination rate, while a. sphearocephala had the lowest one. under -0.3(-) -0.6 mpa, the root length of 10-day-old a. sphearocephala seedling was significantly longer than that of h. scopari ... | 2002 | 12418254 |
