Other claims from this paper (15)
- Intervention effect One thousand ppm 4-Cl retarded maturation of attached snap-bean fruits.
- Intervention effect Fresh weight of treated snap-bean fruits was 11.2% greater than untreated fruit when harvested 1 week after treatment.
- Intervention effect Fresh weight of treated snap-bean fruits was 10.1% greater than untreated fruit when harvested 2 weeks after treatment.
- Intervention effect Fresh weight of treated snap-bean fruits was 11.4% greater than untreated fruit when harvested 3 weeks after treatment.
- Intervention effect Treated snap-bean fruits contained 2.3% more moisture than untreated fruit when harvested 1 week after treatment.
- Intervention effect Treated snap-bean fruits contained 8.7% more moisture than untreated fruit when harvested 2 weeks after treatment.
- Intervention effect Treated snap-bean fruits contained 14.0% more moisture than untreated fruit when harvested 3 weeks after treatment.
- Intervention effect Treated snap-bean pods were 14% heavier in dry weight than untreated pods at maturity.
- Intervention effect Sprays of 4-Cl at 250 to 1000 p.p.m. reduced the final yield of fresh snap-bean fruit.
- Intervention effect The most concentrated spray (1000 p.p.m. 4-Cl) reduced the final yield of fresh snap-bean fruit by 44%.
- Intervention effect A 50 p.p.m. spray did not significantly reduce snap-bean yield under the conditions used.
- Intervention effect Sprays of 4-Cl at 50 to 1000 p.p.m. increased the water-retaining capacity of snap-bean fruit when harvested and stored.
- Intervention effect The acid retarded the rate of colour change in harvested and stored snap-bean fruit.
- Intervention effect Applying 4-Cl in a wax emulsion was more effective than an equal concentration in aqueous spray in retarding moisture evaporation from harvested snap-bean fruit.
- Intervention effect Fruit sprayed with the wax-growth-regulator mixture lost about 25% less moisture than unsprayed fruit during the first week of storage.
