e0“To select resistant germplasm resources and understand the growth and physiological responses of kiwifruit ( Actinidia sp.) to drought stress, five species, Actinidia macrosperma (Acma), Actinidia longicarpa (Aclo), Actinidia deliciosa (Acde), Actinidia hemsleyana (Ache), and Actinidia valvata (Acva), were assessed under tissue culture conditions. Rootless seedlings of five species were cultured in a medium containing polyethylene glycol [PEG (formula weight 8000)] to induce drought stress (0%, 5%, 10%, 15%, and 20%). After a 30-day culture, three growth indices [fresh weight (FW), plant height (PLH), and leaf number (LN)] and six physiological indices were determined, and the drought damage index (DDI) was determined. The DDIs of five species increased, and three growth indices decreased with increasing PEG concentrations”

- Intervention effect Fresh weight, plant height and leaf number decreased with PEG concentration.
- Intervention effect SOD activity increased significantly in Acma, Aclo and Ache at 20% PEG.
- Intervention effect POX activity stayed stable in Acde, Ache and Acva at 20% PEG.
- Intervention effect CAT activity increased sharply in Acma and Acva.
- Intervention effect Soluble sugar rose slightly in Acma, Aclo, Acde and Ache.
- Intervention effect Soluble sugar decreased in Acva.
- Intervention effect Proline increased significantly in Acma and Acva.
- Intervention effect Malondialdehyde tended to increase under drought stress in all species.
- Observation Drought tolerance ranked Acma above Acva, Acde, Aclo and Ache.
- Recommendation Acma and Acva were identified as promising kiwifruit breeding materials.
