Other claims from this paper (10)

Intervention effect Selfing reduced seed maturation relative to open pollination.
Observation Selfed progeny had high postgermination survival depression through age 23.
Observation Height after 23 years did not differ significantly by progeny type.
Observation Flowering after 23 years did not differ significantly by progeny type.
Observation Cumulative inbreeding depression was high.
Observation Cumulative inbreeding depression varied significantly among maternal families.
Association Early and later inbreeding depression were not significantly correlated among maternal parents.
Observation Progeny size differences diminished over time.
Mechanism Authors argue that self-fertilization inefficiently purges genetic load in Scots pine because selfed individuals are nearly entirely lost.
Mechanism Authors infer that the population is effectively randomly mating and outcrossing.

Intervention effect At 5 degrees C, aspen root growth was completely inhibited relative to 20 degrees C.
Intervention effect At 10 degrees C, aspen root growth was inhibited by 97% relative to 20 degrees C.
Intervention effect The 5 and 10 degree C treatments reduced aspen shoot growth, leaf size and total leaf area.
Intervention effect The 5 and 10 degree C treatments inhibited aspen root water flow.
Observation Aspen grown at 5 degrees C for 28 days showed increased root water flow when measured at 20 degrees C.
Association Reduced root flow in seedlings grown at 5 and 10 degrees C coincided with decreased stomatal conductance, net assimilation and shoot water potentials.
Association Root water flow correlated positively with aspen leaf size, total leaf area and shoot length.
Association Root water flow correlated positively with new aspen root growth.
Intervention effect Transfer from 5 to 20 degrees C for 24 hours increased root flow, shoot water potential and net photosynthesis.
Intervention effect Transfer from 10 to 20 degrees C slightly increased shoot water potential.
Intervention effect Transfer from 20 to 5 degrees C greatly reduced root flow, stomatal conductance and net photosynthesis.

Jennifer Riehl Koch; Amy J. Scherzer; Steven M. Eshita; et al. PLANT PHYSIOLOGY 1998. doi:10.1104/pp.118.4.1243

Other claims from this paper (5)

Intervention effect Ozone decreased photosynthetic rate in both clones.
Intervention effect Ozone decreased stomatal conductance in both clones.
Association Ozone-induced mRNA levels for four defense-related genes were significantly higher in tolerant than sensitive plants.
Association Wound-induced mRNA levels for these genes were higher in tolerant plants than sensitive plants.
Mechanism The authors suggest ozone tolerance involves salicylic-acid- and jasmonic-acid-mediated signaling.
