Title

Control of Seed Respiration and Growth in Vicia faba by Oxygen and Temperature: No Evidence for an Oxygen Diffusion Barrier

Ries de Visser; Harold M. Dekhuijzen; Dick R. Verkerke PLANT PHYSIOLOGY 1990. doi:10.1104/pp.93.2.668

Other claims from this paper (10)

Intervention effect The rate of dry matter accumulation by Vicia faba cv. Minica seeds increases with temperature between 16 and 26 degrees C.
Intervention effect The duration of seed dry matter accumulation decreases with temperature.
Intervention effect O2 uptake rates of intact seeds in buffer were only 9 to 15% of those in air.
Intervention effect In buffer, the respiration rate of intact seeds decreased at a pO2 below air saturation (21 kilopascals).
Intervention effect In buffer, separated seeds showed a decline of O2 uptake only below 80% of air saturation.
Intervention effect In air, embryo excision had no effect on the sensitivity of seed respiration to pO2 at both 20 and 26 degrees C.
Intervention effect In air at 20 degrees C, separated and intact seeds showed similar rates of O2 uptake.
Observation Oxygen uptake by intact seeds, both halfway and beyond the linear growth phase, showed a temperature coefficient Q10 of 2.3.
Observation Oxygen uptake by intact seeds was insensitive to pO2 in the range of 80 to 100% of ambient.
Mechanism The results indicate that V. faba seed respiration in air is not limited by the diffusion of O2 into the seed.

Association Cultivar germination or vigor was uncorrelated with acetone immersion.
Recommendation Acetone could carry fungicide into some cultivar seeds without harming germination or vigor.

The Effect of Artificial Acid Rain on the Growth and Competition of Echinochloa crus-galli and Digitaria sanguinalis

Jin‐Kyung Kim; Do-Soon Cho The Korean Journal of Ecology 1996

Other claims from this paper (8)

Intervention effect Density variation and simulated acid rain treatment showed little effect on interspecific competition between E. crus-galli and D. sanguinalis.
Observation The ratio diagram always showed predominance of E. crus-galli in competition regardless of density and pH.
Observation Relative yield total showed intraspecific competition was stronger than interspecific competition in both species.
Intervention effect Simulated acid rain showed little effect on the growth of E. crus-galli and D. sanguinalis.
Intervention effect Height growth of both species did not differ from the control (pH 5.6).
Intervention effect Root/shoot ratio increased as the pH of simulated acid rain decreased.
Intervention effect Growth of total dry weight of both species was not influenced by the change of pH.
Observation D. sanguinalis showed a visible sign of white spots on leaves at pH 2.8.

The effect of photoperiod and temperature on growth and frost resistance of winter rye root systems

Marilyn Griffith; Heather C.H. McIntyre Physiologia Plantarum 1990. doi:10.1111/j.1399-3054.1990.tb02112.x

Other claims from this paper (10)

Association Root system growth was influenced by the interaction of temperature and photoperiod.
Observation Maximum shoot growth at 20°C occurred under a 24-h photoperiod.
Observation Maximum shoot growth at 5°C occurred under a 16-h photoperiod.
Association Maximum shoot growth correlated with a high root:shoot ratio in both temperature treatments.
Intervention effect Short photoperiod and low temperature delayed new adventitious root production.
Intervention effect Short photoperiod induced frost tolerance in existing roots.
Intervention effect Cold temperature retarded developmental processes within roots.
Intervention effect At 5°C, first-order lateral roots developed more slowly than at 20°C.
Intervention effect At 5°C, metaxylem differentiation was slower than at 20°C.
Intervention effect At 5°C, endodermal wall suberization was slower than at 20°C.

Intervention effect In rice seedlings, the dry weight of shoot in SLH was significantly lighter than that in YSS at the time of seedling harvest.
Intervention effect In rice seedlings, the shoot in SLH was as long as that in YSS.
Intervention effect In rice seedlings, The increase of dry weight of shoot and the decrease of dry weight of grain were smaller in SLH than in YSS during the raising of seedlings.
Intervention effect In rice seedlings, the content of soluble sugars in the grain of SLH was apparently lower than that of YSS.
Intervention effect In rice seedlings, Crop growth rate and mean leaf area index of SLH were lower than those of YSS.
Intervention effect In rice seedlings, net assimilation rate of SLH was similar to that of YSS.
Intervention effect In rice seedlings, The size of leaf blades in SLH was markedly smaller than that in YSS.
Intervention effect In rice seedlings, no significant difference was observed in the rates of photosynthesis and dark respiration in leaf blades between SLH and YSS.
Mechanism Carbohydrate supply from endosperm to shoot was inferred to be less in SLH.
Mechanism The authors attribute reduced leaf growth in SLH to insufficient carbohydrate supply from endosperm.
Mechanism The authors attribute lower dry matter production in SLH to reduced leaf growth.
