Other claims from this paper (15)
- Intervention effect Ethephon reduced soybean stem length and leaf area, especially in the lower plant.
- Observation Upper stem elongation compensated for lower stem shortening under 1987 V3 ethephon treatment.
- Intervention effect Ethephon increased lodging in 1987.
- Observation The smaller drought stressed soybean plants did not lodge in 1988.
- Intervention effect V3 ethephon application increased leaf abscission relative to later application.
- Association Basal stem total nonstructural carbohydrate and starch declined as ethephon rate increased at V3.
- Association Basal stem total nonstructural carbohydrate and starch increased with ethephon rate at V7.
- Association Midstem free sugar levels declined with increasing ethephon rate.
- Intervention effect Ethephon reduced relative water content in R5 lower stems relative to midstem segments in 1988.
- Intervention effect Ethephon reduced leaf area more than plant height, especially in the lower plant.
- Mechanism Authors suggest ethephon induced leaf area loss may have reduced yield in every treatment.
- Mechanism Ethephon may have lowered lower stem carbohydrate status under V3 treatment.
- Intervention effect Ethephon reduced pod number in the lower plant under V3 application.
- Intervention effect Ethephon did not reduce lower plant pod number under V7 application.
- Observation Despite the intended stem morphology, other effects weakened lower stem bending resistance in 1987.
