Early leaf and flower senescence are likely ethylene-dependent, either due to … WebAs concentrations of ethylene increase, flower buds will also abscise. When salvia are exposed to ethylene for 24 hours, even 0.01 ppm ethylene results in the loss of a few petals. Increasing amounts of ethylene cause more flower abscission, with 1 and 10 ppm ethylene resulting in the loss of 50 to 85 percent of the petals, respectively (Figure 3). how to teach a dog sign language
