如果科学家弄清楚什么样的温度和湿度最适合树木生长，他们就可以推算出那一年的气候情况。
If scientists know what temperature and moisture level make the tree happy, they can use the thickness to gauge what the climate was like that year.
他说，欧芹最适合的生长温度是在21度以下。
He says parsley grows best when temperatures are under twenty-one degrees Celsius.
换言之，水稻生长最适温度在营养生长阶段高，而生殖生长阶段低。
In other words, the optimum temperature for rice growth was high at vegetative stage and low at reproductive stage.
