Aref A. Abdul‐Baki; James D. Anderson Crop Science 1970. doi:10.2135/cropsci1970.0011183x001000010012x

Other claims from this paper (15)

Association Sugar leaching increased with seed age.
Intervention effect Sugar leaching increased with mechanical injury of endosperm.
Intervention effect Accelerated aging left sugar leaching unchanged unless viability was severely reduced.
Observation Leached sugars, especially glucose, made up a significant portion of seed sugars at 4, 8 and 12 hours of germination, even in highly viable seeds.
Intervention effect Aging seeds for 2, 5 and 8 years increased sugar leaching.
Intervention effect Aging seeds for 2, 5 and 8 years reduced viability.
Intervention effect Mechanical injury increased sugar leaching without affecting viability.
Intervention effect Accelerated aging up to 12 days did not affect sugar leaching.
Intervention effect Accelerated aging up to 12 days reduced viability.
Recommendation Sugar measurements were judged an unreliable index of seed viability.

Observation The endosperm held 80 to 90% of total seed glucose and sucrose.
Observation The embryo held 10 to 20% of total seed glucose and sucrose.
Association Glucose increased in both embryo and endosperm as germination progressed.

Effects of temperature and irradiance on stigma exsertion, ovule viability and embryo development in tomato

R. Fernandez-Muñoz; J. Cuartero Journal of Horticultural Science 1991. doi:10.1080/00221589.1991.11516167

Other claims from this paper (10)

Intervention effect In fully opened Marroquí flowers, stigma level was highest under high temperature.
Intervention effect In fully opened Moneymaker flowers, stigma level was highest under high temperature and stigmatic exsertion was significant.
Association Red Top stigma levels depended little on temperature.
Intervention effect Low light produced higher stigma levels than normal illumination.
Association Illumination affected stigma levels less than temperature did.
Association Treatment-related variation in stigma level depended more on stamen length than pistil length.
Observation Stigma exsertion followed treatment only at advanced flower-opening stages.
Intervention effect The high temperature and low light treatment showed the least ovule viability.
Intervention effect Ovules under high temperature were significantly more receptive early in development than under low temperature.
Mechanism The authors conclude that winter failures of tomato fruit set appear unrelated to stigma level, ovule viability, or early embryo interruption.
