| Abstract: | Moisture loss rate of Jojoba leaves after drought simulation treated by different marination time with 30% and 50% solutions of PEG-6000 were determined as a parameter of subsistence of Jojoba. And conductivity of Jojoba shoots in vitro was tested after treated by different cold acclimation time or different frozen temperature. The results verified that it was an easy, quick and useful method using moisture loss rate under PEG-6000 treatment and conductivity as parameters of physical state of Jojoba plants under abio-stress. |
