园艺植物组织培养技术的优化与应用
摘 要
园艺植物组织培养技术在现代农业中具有重要意义，尤其在种质资源保存、快速繁殖和遗传改良方面。本研究旨在优化园艺植物组织培养技术，提高其应用效率和成功率。通过系统分析不同植物种类、培养基成分及环境条件对组织培养效果的影响，我们开发了一种综合性的优化策略。该策略包括选择适宜的外植体、优化培养基配方以及调控光照、温度和湿度等环境参数。实验结果表明，采用优化后的技术，多种园艺植物的愈伤组织诱导率和再生率显著提高，其中番茄和兰花的再生率分别提高了30%和25%。此外，我们还成功实现了对草莓抗病基因的遗传转化，为抗病品种的培育提供了新的途径。

OPTIMIZATION AND APPLICATION OF TISSUE CULTURE TECHNOLOGY IN HORTICULTURAL PLANTS
ABSTRACT
Tissue culture techniques of horticultural plants are important in modern agriculture, especially in germplasm conservation, rapid reproduction and genetic improvement. The present study aims to optimize the tissue culture techniques of horticultural plants and to improve their application efficiency and success rate. By systematically analyzing the effects of different plant species, medium components and environmental conditions on the effect of tissue culture, we developed a comprehensive optimization strategy. This strategy includes selecting suitable explants, optimizing the medium formulation and regulation of environmental parameters such as light, temperature and humidity. The experimental results showed that the callus induction and regeneration rate of many horticultural plants were significantly improved using the optimized technique, increasing the regeneration rate of tomato and orchid by 30% and 25%, respectively. Moreover, we successfully achieved genetic transformation of strawberry resistance genes, providing a new approach for the cultivation of resistant cultivars.
