Abstract

Abstract:

Objective: This study investigated the effects of salt stress on the growth and photosynthesis of Magnolia wufengensis grafted seedlings, in order to explore the adaptation mechanism and ability of M. wufengensis under salt stress and provide the basis for the protection and introduction of germplasm resources. Method: A pot experiment was carried out with the M. wufengensis 'Jiaohong Ⅱ' grafted seedlings, and five NaCl gradients (0 (CK), 0.1% (T1), 0.2% (T2), 0.3% (T3) and 0.4% (T4)) were set. After 20 days of the treatment, the growth status, leaf characteristics, gas exchange parameters, chlorophyll fluorescence parameters, and photosynthesis response curve were measured. Result: Salt stress had no significant effect on seedling height relative growth, ground diameter relative growth, stem biomass and root-shoot ratio of M. wufengensis grafted seedlings and had a significant effect on leaf, root biomass and plant dry weight. The leaf biomass, root biomass and dry weight of T1 were higher than CK, while the other salt-treatments were lower than CK. With the increase of salt concentration, the leaf thickness of the grafted seedlings of M. wufengensis was increased first and then decreased, and the leaf thickness of T1 treatment was the largest, reaching 0.30 mm; the dry weight of the leaves was decreased. When the salt concentration was ≥ 0.2%, the content of chlorophyll a, chlorophyll b, total chlorophyll, and the net photosynthetic rate decreased significantly; meanwhile, the value of chlorophyll a/b, stomatal conductance, and transpiration rate decreased significantly under salt stress. Compared with the control, the chlorophyll fluorescence parameters of the M. wufengensis grafted seedlings under salt stress decreased to different degrees. Besides, salt stress significantly reduced the dark respiration rate, light compensation point and light saturation point, and there was no significant difference among those salt treatments. Conclusion: Salt stress significantly affects the growth and photosynthesis of Magnolia wufengensis grafted seedlings, by reducing the photosynthesis activity of leaf cells. In terms of the comprehensive indicators, there is no significant difference in growth and photosynthesis of M. wufengensis grafted seedlings between 0.1% salt stress and the control.

Key words: Magnolia wufengensis, salt stress, photosynthesis, photosynthetic fluorescent, light response curve
