From: Differences in PItotal of Quercus liaotungensis seedlings between provenance
Regression analysis of Quercus liaotungensis seedlings between PItotal and precipitation of the warmest quarter in provenance. YQ represents the Yangqu test site, and SJ represents the Sanjiao test site. The dotted lines indicate the precipitation of the warmest quarter in two test sites. R2 of Sine fit of YQ is 0.90, P < 0.01, and R2 of Sine fit of SJ is 0.77, P < 0.01.
