柑桔病毒类病害是柑桔生产的潜在危险,由于种类多、分布广、削弱树势、降低产量、影响品质,难于防治,已成为影响柑桔业发展共同关注的重要问题。世界柑桔主产国中,已将建立柑桔无病毒良种繁育体系,推广无病毒苗木作为柑桔生产发展与科研的基础工作。 Citrus diseases are the potential dangers of citrus production. Due to its wide variety, wide distribution, weakening of tree vigor, decreasing yield, affecting quality and being difficult to control, citrus diseases have become an important issue of common concern for the development of citrus industry. Among the major citrus producing countries in the world, the establishment of a virus-free seed breeding system for citrus has been promoted to promote virus-free seedlings as the basic work for the development and research of citrus production.
