The first two PCA axes (Fig.3) accounted for 72 % of the total variance.The first axis (51 % of explained variation) showed a high positive correlation (r ＞0.6) with all the germination variables,and clearly separated the collections of three species (Group A) characterized by high germination ([85 %) at the three thermoperiods after cold stratification (Table 4).On the other hand,differences along the second axis (21 % of explained variation) were mainly correlated with the germination of stratified seeds at 14/4 \x03C (r = 0.6) and 30/20 \x03C (r = -0.65).

Answer 1

第一PCA轴（图3）占72%的总方差.第一轴（的变化）51%呈高度正相关（r＞0.6）所有的发芽变量,并清楚地分离的三种集合（A组）具有较高的萌发（85%）在三个处理后的低温层积（表4）.另一方面,沿着第二轴的差异（解释21%变异）主要与分层种子萌发的14 / 4 \x03 C（R = 0.6）和30 / 20 \x03 C（R = 0.65）.
