假色槭驯化苗木物候特征观察

对假色槭驯化苗进行生物学物候观测发现:(1)假色槭驯化苗木随着龄级的增长,树皮由光滑趋于粗糙,颜色由绿转红最后趋于深灰,皮孔从有趋于消失.(2)假色槭观赏期约20天左右,最佳观赏时间在9月下旬至10月初.(3)假色槭驯化苗的树形分化明显,灌木状株型占明显优势.(4)灌木状植株的萌生条生长迅速,当年生长量达80cm以上;有明显主干植株的生长量小,仅在30cm左右.

The Phenology Characteristics Observation on Domesticated Seedlings of Acer pseudo - sieboldianum

A biological observation on phenology of domesticated seedlings of Acer pseudo-sieboldianum was conducted.The result showed that(1)As they grow older,their skins will turn from lubricity to roughness,and the color of their leaves will turn from green to red which will disappear finally.At the same time,their lenticels will disappear little by little.(2)Date of enjoying their red leaves can last about 20 days during when the best time is from the last ten-day of September to the first ten-day of October.(3) Shape of their domesticated seedlings differentiates obviously,and shrub-type plants are dominant.(4)The new-born twigs of shrub-type plants grow quickly up to over 80cm in one year.While those of arbor-type plants grow slowly relatively up to about 30cm.
