Gui Jia Journal of Plant Ecology 2006
Other claims from this paper (12)
- Intervention effect Ammopiptanthus mongolicus seeds presoaked in water at 60 ℃ gave the highest germination vigor, with 56.4% germinated within one day at 28 ℃.
- Observation The optimal temperature for hypocotyl and radicle elongation of A. mongolicus seedlings is 25 ℃ to 30 ℃, lower than that for germination initiation (30 ℃).
- Intervention effect Temperature above 40 ℃ would likely have a detrimental effect on A. mongolicus seedling growth in the germination test.
- Intervention effect The percentage of abnormal seedlings was only 5.2%-8.6% at 30 ℃ to 40 ℃, much lower than 28.1% at 15 ℃.
- Intervention effect In container culture, sixty three percent of seedlings emerged from sandy soil within 7 days versus only 11% in clay loam.
- Intervention effect Seedlings from seeds larger than 5 mm tended to be stronger and more vigorous than those from smaller seeds in early growth.
- Intervention effect Seedlings from larger seeds took about 57 days to reach a constant survival rate above 56.3%, whereas those from smaller seeds took over 70 days to reach 35.4%.
- Observation Seedlings from smaller seeds showed high susceptibility to pathogen and continuous death within 70 days.
- Intervention effect Soaking in hot water at 40 ℃ to 60 ℃ promoted the germination rate of A. mongolicus.
- Intervention effect Soaking in hot water at 40 ℃ to 60 ℃ decreased the percentage of remaining hard-coated seeds of A. mongolicus.
- Intervention effect Extremely high or low temperature had a detrimental effect on germination and seedling performance of A. mongolicus.
- Intervention effect Seeds smaller than 5 mm in diameter showed reduced seedling quality and seedling performance.
