Abstract:
OBJECTIVETo study the effect of water stress on the content of scutellarin and caffeate in Erigeron breviscaps.
METHODFv/Fm, N content, as well as the content of scutellarin and caffeate under three water grads were measured.
RESULT AND CONCLUSIONFv/Fm of the plant decreased significantly in 8% and 23% water treatment, that proved drought and waterlogging occurred. Under the two conditions, the contents of N were lower but the contents of active constituents were higher than those under 15% treatment. The results support the carbon-nutrient balance hypothesis and the "stress effect hypothesis" for the formation of geo-herbs.
