苹果或海棠经２５～１００ｍｇ／ＬＰＤＪ（丙基双氢茉莉酮酸酯）处理后，叶片光合速率提高，根系活力增强，茎叶中内源ＡＢＡ含量增加，气孔关闭。２５ｍｇ／Ｌ和１００ｍｇ／Ｌ处理未能降低叶片的蒸腾速率，却降低了气孔阻力；而５０ｍｇ／Ｌ处理不仅降低了蒸腾速率，同时也增加了气孔阻力，与１００ｍｇ／ＬＡＢＡ处理效果近似。推测ＰＤＪ可能通过促进ＡＢＡ的合成增加植物对逆境的抵御能力，认为ＰＤＪ作为外用生长调节物质有希望成为ＡＢＡ的替代品。
After treated with 25 ~ 100mg / LPDJ (propyl dihydrojasmonate), the photosynthetic rate and root vigor of apple or begonia increased, the content of endogenous ABA increased and the stomatal closed. However, treatment with 25 mg / L and 100 mg / L did not reduce leaf transpiration rate but decreased stomatal resistance. However, 50 mg / L treatment not only reduced transpiration rate but also increased stomatal resistance, which was similar to 100 mg / L treatment. It is speculated that PDJ may increase the plant’s ability to resist adversity by promoting the synthesis of ABA. PDJ is expected to become a substitute for ABA as a growth regulating substance.
