Abstract

The invention discloses the application of pipecolic acid as a plant disease resistance activator in the prevention and treatment of apple fruit diseases, and belongs to the technical field of plant induced disease resistance. The pipecolic acid is used to enhance the activity of defense enzymes in plants and increase the expression of disease resistance genes. The defense enzymes are PAL, PPO, POD and SOD, and the disease resistance genes are PR1 and PR5. The concentration is 0.2mmol·L ‑1 ~0.5mmol·L ‑1 The pipecolic acid solution can be used to induce disease resistance of apple fruit and prevent and control apple fruit diseases. The pipecolic acid solution of the present invention itself has no in vitro bactericidal or bacteriostatic activity, and can only induce plant disease resistance under living conditions, and the disease resistance induced by apple fruits has the characteristics of long duration and wide disease resistance spectrum, and Environmentally friendly and safe, it is not suitable to cause drug resistance of pathogenic bacteria; the method of use is simple, the concentration is low, and the dosage is small.

Description

technical field

[0001] The invention belongs to the technical field of plant induced disease resistance, and in particular relates to the application of pipecolic acid as a plant disease resistance activator in the prevention and treatment of apple fruit diseases. Background technique

[0002] Apple is an important economic crop and export fruit in my country. Its cultivation area and output both rank first in the world. However, the export rate of apples is less than 3% of the total output. Apple diseases, especially fruit diseases, are an important factor causing this phenomenon. The diseases caused by fungal infection in every link of apple production have brought huge losses to people. Apple fruit diseases not only cause fruit rot during the growth period, but also cause rot during post-harvest storage, fresh-keeping and transportation, causing serious economic losses.

[0003] Apple fruit diseases mainly include: apple ring spot (Botryosphaeria dothidea), gray mold (Bo...
