Other claims from this paper (7)
- Intervention effect Application of 2,4-DP butoxyethyl ester around 60 days after bloom increased endogenous ethylene production.
- Intervention effect Application of potassium-salt 2,4-DP around 60 days after bloom increased endogenous ethylene production.
- Intervention effect The auxin treatments increased fruit-skin anthocyanin concentration and red blush.
- Intervention effect The auxin treatments did not cause fruit drop.
- Intervention effect Both auxins accelerated fruit maturation.
- Intervention effect Neither auxin harmed fruit quality at harvest or after six months at 0°C.
- Recommendation The authors recommend 2,4-DP sprays to improve harvest apple color without harming other fruit quality traits.
