e0“Pearson's correlation coefficients showed that the trade‐off hypothesis on energy allocation between phytochemical defense and plant growth was not supported by the data from the L. olgensis seedlings that were exposed to Pb stress”

Other claims from this paper (5)
- Intervention effect Pb exposure significantly reduced larch seedling growth.
- Intervention effect Pb exposure significantly reduced gypsy moth larval weight, survival and antioxidant capacity.
- Intervention effect Pb-treated needles showed low-dose promotion and high-dose inhibition of protease inhibitors.
- Intervention effect Pb-treated needles showed low-dose promotion and high-dose inhibition of condensed tannin and total phenolics.
- Mechanism The authors suggest elemental defense may replace phytochemical defense against gypsy moth larvae under Pb stress.
