Other claims from this paper (11)

Intervention effect Early 100% recommended-dose ethylene did not change onion seed yield.
Intervention effect Early 100% recommended-dose ethylene increased thousand seed weight by 3.2%.
Intervention effect The 150% recommended ethylene dose decreased onion seed yield by 33.5% regardless of application timing.
Intervention effect Chitosan had no apparent crop effect at 100% recommended-dose ethylene.
Intervention effect Under 150% recommended-dose ethylene, chitosan increased onion seed yield.
Intervention effect Under 150% recommended-dose ethylene, chitosan slightly increased thousand seed weight without statistical significance.
Observation Fresh onion seed germination was 92%.
Intervention effect Seventeen months of aging reduced onion seed germination by 14%.
Intervention effect Ethylene and chitosan treatments did not change the onion germination pattern.
Mechanism The authors suggested that high-dose ethylene yield loss may reflect delayed flowering during a relatively dry month.
Mechanism The authors proposed that chitosan sustained yield under 150% recommended-dose ethylene through physical protection from transpiration.

Intervention effect Higher temperatures reduced whole-plant dry matter accumulation during grain filling.
Intervention effect Higher temperatures shortened the period from 18 days after silking to complete leaf senescence.
Intervention effect Higher temperatures lowered the rate of whole-plant dry matter production to a limited extent.
Intervention effect Grain yield per plant was lower under higher temperatures.
Intervention effect Temperature had no observed effect on kernel growth rates.
Intervention effect Temperature had no observed effect on kernel number per ear.
Mechanism Kernel dry-matter gain during rapid grain filling drew on stored assimilates and current photosynthesis.
Intervention effect At the highest temperature, remobilized assimilates accounted for a greater share of kernel weight gain.
Intervention effect Higher night temperatures may increase the share of kernel gain supplied by remobilized stored dry matter.

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.
