Although roses are not classified as highly sensitive to ethylene, their response to ethylene varies .In this study, we
examined the effect of exogenous ethylene on apparent properties of cut Rose (Rosa hybrida) cv. Cool Water with
low vase life through quantifying the ethylene receptor gene, RhETR3. The cut flowers were treated with 10 ppm
ethylene concentration and the expression of ethylene receptor gene was measured before ethylene treatment, 24 h,
48 h and 72 h after ethylene treatment via real-time RT-PCR. We found that the level of relative expression ethylene
receptor gene, RhETR3 had significant increase with ethylene treatment during senescence and ethylene caused
accelerated of senescence symptoms such as petal fading and bent neck. Moreover, the relative expression of
RhETR3 remained in low level in controls because of its negative regulatory function.
