Abstract
This study was conducted to evaluate the
agro-biological characteristics of the Bac Son yellow mandarin variety (Citrus
reticulata Blanco), a specialty fruit of Bac Son district, Lang Son
province. The analysis revealed that Bac Son mandarin displays strong growth
potential with an average tree height of 8.34 ± 1.04 m, trunk diameter of 38.23
± 2.60 cm, and canopy diameter of 7.22 ± 0.89 m. Leaves averaged 10.69 ± 2.58
cm in length and 3.60 ± 1.19 cm in width and contain characteristic essential
oils. Flowers are clustered, typically with 6 petals; the average petal length
is 2.04 ± 0.28 cm and the number of stamens is about 20.74 ± 3.53. Fruits
weighed on average 107.22 ± 4.69 g with a diameter of 7.72 ± 0.83 cm; the pulp
is juicy with a distinctive flavor. However, this variety is affected by pests
and diseases such as stem borers, psyllids, and greening disease. The study
recommends technical measures including improved cultivation practices, the use
of disease-free planting material, and integrated pest management to enhance
production efficiency and fruit quality of Bac Son yellow mandarin.
