Abstract

Three Ilex species：Ilex rotunda，I. chinensis，and I. integra，were compared with I. micrococca （a control which did not have deep dormancy），for physiological responses to seed dormancy-breaking. The medicinal components，hormones，and enzyme activities were measured during stratification. Results showed that compared to the control there was an active metabolism in seeds of the three Ilex plants with lipid content decreasing，while starches and reduced sugars increased. Catalase（CAT） activity decreased；peroxidase（POD） activity increased；and abscisic acid （ABA） content decreased. Ratios of gibberellic acid （GA3）/ABA，indole-acetic acid （IAA）/ABA，and zeatin-riboside （ZR）/ABA increased. Before stratification ABA in I. rotunda，I. chinensis，and I. integra was higher than I. micrococca，but after stratification it was lower. Also，before stratification GA3 /ABA in I. rotunda，I. chinensis，and I. integra was lower than the control but higher after stratification. Additionally，compared to I. micrococca，I. rotunda and I. chinensis had similar characteristics. ［Ch，1 fig. 2 tab. 13 ref.］
