Abstract:

Taking the container seedlings of three improved Acer rubrum varieties ‘Autumn Flaze’，‘October Glory’ and ‘Red Sunset’ as materials，the variation process of autumn leaves color was studied by the method of taking pictures for the identical views within the stipulated time.The results showed that autumn leaf ornamental period of ‘Autumn Flaze’ kept for 34 days from October 26 to November 28，the best ornamental period continued for about 7 days，autumn leaf color period and leaf fall period were 21 days and 27 days respectively，the variation process of leaf color was from green to yellow-green，orange-red and red；autumn leaf ornamental period of ‘October Glory’ continued for about 28 days from October 26 to November 22，the best ornamental period lasted up to 10 days，autumn leaf color period and leaf fall period were 21 days and 27 days respectively，the variation process of leaf color was from green to yellow-green,and yellow；autumn leaf ornamental period of ‘Red Sunset’ was 32 days from October 26 to November 26，the best ornamental period was about 10 days，autumn leaf color period and leaf fall period were 22 days and 23 days respectively，the variation process of leaf color was from green to yellow-green，yellow and orange-red.In conclusion，‘Red Sunset’ worked the best ornamental effects，followed by ‘October Glory’ and ‘Autumn Flaze’，which provided a reference for application of the above three varieties in garden.
