Other claims from this paper (9)

Method / resource The lodging model explained about 58% of variation in pea datasets.
Method / resource The model can predict relative effects of load, height, stem diameter, stem wall thickness, and yield on lodging susceptibility.
Association Plant height was strongly correlated with lodging susceptibility in pea.
Association Stem diameter was positively correlated with lodging resistance in pea.
Association Stem wall thickness appeared to have no major effect on lodging resistance in pea.
Association Doubling plant height would double stem material in pea.
Association Doubling plant height is expected to increase pea stem stress fourfold.
Association Doubling stem diameter is expected to increase pea stem material fourfold.

Other claims from this paper (10)

Observation The effect of exogenous ABA on photosynthesis was most prominent one day after spraying.
Intervention effect ABA decreased photosynthetic CO2 assimilation in pea and wheat.
Intervention effect ABA increased cyclic electron flow in pea and wheat.
Association ABA-associated decreases in CO2 assimilation and increases in cyclic electron flow were interconnected.
Intervention effect ABA decreased mesophyll conductance to CO2.
Intervention effect ABA did not significantly influence leaf water conductance.
Intervention effect ABA did not significantly influence Calvin–Benson-cycle CO2 fixation parameters.
Mechanism The decrease in mesophyll CO2 conductance was proposed to be related to decreased plasma-membrane CO2 conductance.
Mechanism H+-ATP-ase inactivation and extracellular pH changes were proposed as a mechanism for decreased conductance.
Intervention effect The metabolic component of electrical resting potential decreased after ABA treatment.

Other claims from this paper (11)

Intervention effect Pea growth decreased under Fe deficiency or excess, more strongly as the stress was prolonged.
Observation The leaf area ratio of pea was only slightly affected by Fe stress.
Intervention effect Under Fe deficiency, leaf weight ratio and specific leaf area showed opposite trends.
Intervention effect Specific leaf area of pea tended to increase under Fe deficiency.
Intervention effect Specific leaf area of pea tended to decrease under excess Fe supply.
Intervention effect Fe deficiency lowered pigment content of pea when chlorosis was well manifested.
Intervention effect Fe deficiency raised the chlorophyll a/b and carotenoid/chlorophyll ratios of pea when chlorosis was well manifested.
Observation Significant changes in chlorophyll fluorescence of pea were observed only in strongly chlorotic plants.
Intervention effect Pea plants deprived of iron had low actual PS II efficiency at days 34 and 41.
Mechanism Low PS II efficiency of iron-deprived pea was attributed to a lower proportion of open PS II centers and lower excitation capture efficiency.
Intervention effect Under partial Fe deficiency, the relative growth rate of pea was high during the last week of the experiment.
