Stem cold hardening developed to different levels in citrus types tested in controlled environments. Exotherms indicated ice spread was more uniform and rapid in unhardened than in cold-hardened stems. All attempts to inhibit the functioning of citrus leaves resulted in less cold hardening in the stems. Citrus leaves contribute a major portion of cold hardening in the wood.
在受控环境下测试的柑橘品种中，茎的抗寒硬化发展到不同程度。放热表明，在未硬化的茎中，冰的扩散比在硬化的茎中更均匀和迅速。所有试图抑制柑橘叶片功能的尝试都导致茎的抗寒硬化程度降低。柑橘叶片对木材的抗寒硬化有很大贡献。
