| In this paper,12 different provenances Prunus sibirica from HeLinGeEr wild apricot forest breeding in Inner Mongolia center as experimental material,we measured different light intensities and different indicators under water by using the LI-6400 photosynthesis analyzer. As well as to the Siberian apricot over-wintering stage cold resistance index of the determination of the branches.we want to study different kinds of wild apricot source of the region’s adaptability results are as follows:12 provenance adaptability to water deficit, known ChaErSen adaptability to water deficit is best, drought resistance, the strongest branch right banner adaptability to water deficit, the worst drought resistance.12 provenance adaptability to local cold tolerance, known ChaErSen, KeZuoHouQi, zhalaite and m ditch of cold tolerance at high levels, and bahrain right flag, aru khorchin and ural mountain cold tolerance at low levels, other provenance of cold tolerance at the secondary level.12 provenance of Siberian apricot adaptability to carry on the comprehensive evaluation, KeZuoHouQi, hexigten and ChaErSen stronger adaptability than other provenance, for local strong adaptability; And AoHan, right right flag banner, bahrain and the adaptability of LiangCheng lower than other provenance, weaker for local adaptationThrough the process with different provenance Prunus sibirica and light, drought resistance and cold resistance related physiological indexes of comprehensive measurement, it can be seen that KeZuoHouQi, hexigten and ChaErSen these three provenance is better for the adaptability of huhhot area, the Siberian apricot varieties of Hohhot area selection provides an important theoretical basis. |
