Abstract: Under soil water stress, the water content in the leaves of Mourning Cypress (Cupressus funebris Endl.) is higher than in those of portugnese Cypress (Cupressus lusitanica).Besides, the decreasing rate of relative water content in the former is slower than that in the latter. under drought condition, the accumulation of free proline content was also observed. Between these two cypress species, Mourning has a higher increasing rate than Portugnese, although the total proline content (absolute content) in Mouening is lower than that in Portugnese. The authors suggested that in comparison with the two in the drought resistance, it is better to use increasing rate and ralative content of free proline accumulation.
