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.

Arun Prasad; Amitabha Chattopadhyay; D. V. Singh Communications in Soil Science and Plant Analysis 2003. doi:10.1081/css-120024793

Other claims from this paper (15)

Intervention effect Soil sodicity significantly inhibited sprouting of all Japanese mint cultivars.
Association Sprouting inhibition by soil sodicity was greater in mint cultivars Kalka and Himalaya than in Shivalik and Koshi.
Intervention effect Soil sodicity at ESP 54.0 caused a severe shoot injury symptom in M. citrata, M. cardiaca and M. arvensis after 50 days of transplanting.
Intervention effect Mentha piperita developed shoot injury symptoms at soil ESP 25.0 and 54.0 after 50 and 70 days of transplanting.
Intervention effect Mentha piperita grown on soils with ESP 25.0 and above failed to survive.
Intervention effect Soil sodicity significantly restricted herb yield of mint genotypes.
Intervention effect At ESP 54.0, herb yield of M. citrata decreased by 83.1% over control.
Intervention effect At ESP 54.0, herb yield of M. cardiaca decreased by 92.2% over control.
Intervention effect At ESP 54.0, herb yield of M. arvensis decreased by 89.6% over control.
Intervention effect At ESP 54.0, herb yield of M. piperita decreased by 98.2% over control.
Intervention effect Increasing soil ESP from 1.5 to 25.0 did not significantly affect oil yield of mint species.
Intervention effect Increasing soil sodicity enhanced sodium concentration in shoot tissues of mint genotypes compared with control.
Intervention effect Increasing soil sodicity decreased potassium, calcium and magnesium concentrations in shoot tissues of mint genotypes compared with control.
Mechanism Na-induced calcium nutrition imbalance had a greater impact on growth inhibition and shoot injury in M. piperita than potassium and magnesium nutrition imbalance.
Association Shivalik and Himalaya showed greater tolerance to sodicity than Kalka and Koshi, with a lower increase in Na and maintained high K/Na, Ca/Na and Mg/Na ratios.
