Quality is at the centre of most genetic improvement programs for this crop. However, genetic studies as in other perennial crops take a long time to accomplish due to the long reproductive cycle.
高品质是植物育种工作的重要目标,但茶是多年生作物,繁殖周期长,通过获得子代来研究其遗传特性需要很长时间。

爸爸，我需要记住一个关于植物繁殖周期的单元。
Dad, I need to memorize a unit about the reproductive cycle of plants.
然而，缺乏情况表明卵的大小——每一个繁殖周期下的蛋的数量——远低于产蛋的潜在限制。
Lack, however, suggested that clutch size—the number of eggs a bird lays per breeding cycle—is far below the potential limit of egg production.
还有小鸡的繁殖周期更短，长成更快，鸵鸟要一年，小鸡只要几个月。
And the generation time is quicker. A chicken grows up in a little less time than an ostrich. An ostrich takes a whole year. A chicken takes a few months.
