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.
Recommendation Pea breeders should increase basal stem diameter to increase lodging resistance.

EFFECT OF IRON SUPPLY ON GROWTH AND PHOTOSYSTEM II EFFICIENCY OF PEA PLANTS

V. Nenova; M. Popov http://www.bio21.bas.bg/ipp/gapbfiles/pisa-06/06_pisa_81-90.pdf 2006

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.

Consequence of restricted mitochondrial oxidative metabolism on photosynthetic carbon assimilation in mesophyll protoplasts: Decrease in light activation of four chloroplastic enzymes

Other claims from this paper (10)

Intervention effect Light activation of four chloroplastic enzymes was greater at limiting than optimal CO2.
Intervention effect SHAM decreased light activation of all four enzymes by up to 33% in mesophyll protoplasts.
Intervention effect Oligomycin caused less than 10% decrease in enzyme light activation in protoplasts.
Intervention effect Antimycin A had no significant effect on enzyme light activation in isolated chloroplasts.
Intervention effect Oligomycin had no significant effect on enzyme light activation in isolated chloroplasts.
Intervention effect SHAM had no significant effect on enzyme light activation in isolated chloroplasts.
Intervention effect DCMU reduced light activation of enzymes in protoplasts by up to 78%.
Intervention effect DCMU reduced light activation of enzymes in chloroplasts by up to 69%.
Mechanism Authors suggest that restricting mitochondrial alternative pathway reduces enzyme light activation in mesophyll protoplasts, but not isolated chloroplasts.
Mechanism Authors suggest decreased enzyme activation could be secondary feedback from restricted carbon assimilation.

Other claims from this paper (7)

Intervention effect NaCl and PEG both inhibited pea germination and seedling growth in all cultivars.
Intervention effect All cultivars germinated at all NaCl levels with no significant decrease in germination.
Intervention effect Effects of NaCl on germination and seedling growth were less than those of PEG.
Observation The pea genotypes differed significantly in germination under salt and drought stress.
Observation Bolero appeared more tolerant to salt stress.
Observation Sprinter cv. gave higher values under drought stress.
Mechanism Germination inhibition by NaCl and PEG at equal water potentials was mainly osmotic rather than salt toxicity.
