| Abstract: | To investigate the effects of rootstock Artemisia annua and Artemisia sieversianae for grafting chrysanthemums and to expand the combinations of rootstocks and scions for chrysanthemum grafting, garden chrysanthemums Zhongshan Fenyun and Zhongshan Zichen were used as scions and A. annua and A. sieversianae were used as rootstocks. Then the effects of grafting with four rootstocks and scions combinations on survival and morbidity, growth characteristics(crown width, crown circumference, stem thickness of rootstock, maximum root length, scion dry weight, root dry weight, total dry weight, and root/shoot) and flowering statuses(total number of flowers per plant, fresh weight per flower, dry weight per flower, flower diameter and flowering period) were compared. The results showed that A. annua as rootstock for grafting garden chrysanthemums was better than A. sieversianae in graft survival rate and plant disease resistance, growth characteristics such as crown width, crown circumference, maximum root length, scion dry weight, root dry weight, total dry weight, and root/shoot, as well as flowering statuses such as the total number of flowers per plant, fresh weight per flower and dry weight per flower, and A. annua was more suitable than A. sieversianae as rootstock for grafting garden chrysanthemums. The rootstocks and scions combinations of the variety Zhongshan Zichen and two Artemisia species, especially Artemisia annua, had a clear advantage in terms of the biomass of grafted plants, flower number, and flowering duration. The effects of the combination of A. annua and A. sieversianae with two garden chrysanthemum rootstocks on growth and flowering were clarified, to provide a reference for the study of rootstock interaction in chrysanthemum grafting and the cultivation of garden chrysanthemum grafting forms and their application in the landscape. |
