WITH CLIMATE AND LAND IN THAI NGUYEN Pho Thi Thuy Hang Hoang Thi Cuc Tran Thi Quynh Anh TNU - University of Medicine and Pharmacy ARTICLE INFO ABSTRACT Received 03 3 2021 Kim anh Rosa laevigata Michx. is a basic tree that grows wild in southern China after that they migrated to some provinces in Vietnam and Laos.

However it is necessary to continue to Cutting evaluate if Rosa laevigata Michx will be able to well adapt to the weather Flowering of Rosa laevigata climate as well as the soil in Thai Nguyen province. Therefore this research Michx is conducted in order to determine the growth and development flowering and the fructification of the tree. By experimental method in the field the Flowering period following results were gained Rosa laevigata Michx trees from cutting grow Trung Khanh - Cao Bang and develop very well strong long with big tree-trunks. The trees are free from pests and diseases and have the good ability to grow new leaf buds.
