Abstract:
The mature of H.ammodendron seeds from Fukang，Jimusar and Turpan deserts in Northern Xinjiang were used as experimental materials，contrastive morphological and germination of H.ammodendron seeds from different provenances by the method of field monitoring and laboratory analysis,and the correlation coefficient between seed characteristics and geographical environmental factors were studied.The results showed that the characteristics of longitudinal diameter，transverse diameter,1 000-seed weight,fruiting wing length,germination percentage,germination index and vigor index of H.ammodendron seeds from different provenancesas as Turpan>Jimusar>Fukang.The longitudinal diamete of Turpan seeds were 0.11 mm，0.19 mm longer than Jimsar and Fukang seeds，the transverse diamete of Turpan seeds were 0.24 mm,0.36 mm longer than Jimsar and Fukang seeds，and the 1 000-seed weight of Turpan seeds were 0.46 g and 0.57 g heavier than them，respectively.The germination index and vigor index were 42.78 and 9.41，and which were 6.17%，3.94% and 2.82，1.64 higher than them，significantly(P＜0.05).The salt tolerance of H.ammodendron seeds from different provenances as Turpan>Jimusar>Fukang.The seed germination percentage and germination potential decreased with the increasing of salt concentrations.The seed germination percentage and germination potential were higher than others under the concentration of 0.10 mol?L-1 NaCl.There was significant positive correlation between the 1 000-seed weight and temperature,which had significant negative correlation to latitude and altitude.There was significant positive correlation between fruiting wing length and latitude and precipitatio.The significant positive correlation was found between the germination percentage and longitude in different provenances.
