请生物背景的英语高手帮忙翻译下面的一个句子！
Traditional plant breeding is slow, but is well understood, predictable and controllable. Tissue culturing is much faster, but traits selected for in tissue culture often bring along undesirable “riders “ such as sources or susceptibility to disease.
参考答案:大部分的植物繁殖是缓慢的,但是已被人类深入的了解,可以预测和控制调节的.组织培养相对较快,但是需要进行品质筛选,因为组织培养经常会遗承母体的附带缺点,或是十分敏感容易死亡.
