An increase of the vapor pressure deficit (VPD) of the growth room atmosphere (from 600 Pa up to 2000 Pa) induced a variation in the air VPD inside the vessels used for rose micropropagation. During the photoperiod, the in vitro plants lost water by evaporation. During the night period, depending upon the VPD of the growth room, plants could take water from the vessel atmosphere. According to the intensity of the transpiration, large changes in the growth and morphology were observed: decrease… CONTINUE READING
