  The study was conducted to determine the effects of rootstock type, grafting season, and foliar fertilizer on the survival rate and growth performance of Huong Tich apricot (Prunus mume) scions during the nursery stage. The experiment was carried out at the Vietnam National University of Agriculture from June 2023 to March 2025 using a two-factor experimental design. The study involved three types of rootstocks (plum, apricot, and peach), four grafting times (September, October, November, and December), and two foliar fertilizers (Antonick and Dau Trau NPK). The results showed that grafting in September was the most suitable, enabling better growth of grafted plants and achieving the highest bud-break rate. In particular, grafting onto plum rootstock produceda higher bud-break rate of 63.1% comapred to, apricot (56.7%) and peach (54.4%) rootstocks. During this grafting time, growth parameters such as scion length and diameter, number of leaves, and leaf length and width were all higher than those in the other grafting times across all three rootstock types. In addition, the use of Antonick foliar fertilizer was more effective than Dau Trau NPK in most growth-related parameters.

  Japanese apricot (Prunus mume (Siebold) Siebold & Zucc.) is a valuable temperate fruit tree grown mainly in Northern Vietnam. However, studies on the agronomic characteristics of apricot the local accessions are still lacking, especially those grown in Huong Son, My Duc, Hanoi. This study aimed to evaluate the agro-morphological characteristics of three Japanese apricot accessions (Ta, Yen Bai, Ma Dao) being grown in Huong Son commune. Each local accession was evaluated on 10 trees, each tree was a replication, with the criteria of leaf shape and color; shape, weight and Brix of the fruit, shape and weight of stone and yield of the 3 accessions. The evaluation results showed that the 3 apricot accessions all have round-ovate leaf shape. However, the growth form, color, and weight of the 3 accessions are very different. The growth form of Ta apricot is semi - upright and spread, while Yen Bai apricot and Ma Dao apricot have an semi - upright growth habit. The fruit weight and yield of Ta apricot are also higher than the other accessions. Thus, among the three accessions, Ta apricot grew the best under the cultivation conditions in Huong Son.
