英文摘要	Qilian juniper (sabina przewalskii kom.) and chinese juniper [sabina chinensis (lin.) ant.] are overwintering plants. s. przewalskii, a protected species in china, is distributed in subalpine and alpine area on the qinghai-tibet plateau. s. chinensis is distributed in plain area. we investigated seasonal changes in photoprotective stress compounds such as anthocyanins, activities of three enzymes of ascorbate-glutathione pathway, as well as xanthophyll size and conversion in these species. ascorbate peroxidase (apx), dehydroascorbate reductase (dhar) and glutathione reductase (gr) levels were higher in the low-temperature months, which was associated with changes in anthocyanins and in de-epoxidation index [(a + z)/(v + a + z)]. photochemical efficiency of psii (fv/fm) was lower (< 0.70) during winter and late autumn in both species. during the low-temperature months, s. przewalskii had higher levels of photoprotective stress compounds than s. chinensis. the results suggested that these two species possess cold-induced photoinhibition functions and show the inherent, season-dependent differences in the amounts of the stress-related compounds.
