Title

Invertase activity limits grain yield of maize under salt stress

Birgit W. Hütsch; Muhammad Saqib; Tanja Osthushenrich; et al. Journal of Plant Nutrition and Soil Science 2014. doi:10.1002/jpln.201300345

Other claims from this paper (9)

Intervention effect Salt stress reduced kernel number by 50%.
Observation No assimilate source limitation was observed under salt stress.
Intervention effect Salt stress significantly increased kernel sucrose concentrations in both genotypes.
Intervention effect Salt stress significantly decreased kernel glucose and fructose concentrations.
Intervention effect Salt stress significantly inhibited soluble acid invertase activity to 19% in hydroponics five days after pollination.
Intervention effect Salt stress significantly inhibited soluble acid invertase activity to 50% in soil culture two days after pollination.
Observation The decrease in enzyme activity was equal in both genotypes.
Observation Pioneer 3906 had its highest soluble acid invertase activity at 2 DAP in soil, followed by a steep decline to 8 DAP.
Mechanism Decreased acid invertase activity is interpreted as a key factor limiting kernel setting under salt stress, with additional factors potentially explaining genotype differences.
