Corn germination period: Promote germination and strengthen seedlings

Brassinolide:

Before sowing, soaking seeds with 0.01-0.04 mg/L brassinolide solution for 24 hours can increase the root length of plants, the number of roots of seedlings and dry root weight.

Diethyl aminoethyl hexanoate:

Soaking seeds with 5-20 mg/L diethyl aminoethyl hexanoate for 12 h can increase the root length, root fresh weight, plant height and fresh weight of corn, and can alleviate the damage caused by chlorsulfuron and pyraclostrobin to inhibit the growth of corn to varying degrees. , can promote the normal germination of corn.Mixed with 10 mg/L diethyl aminoethyl hexanoate and herbicide sprayed at the 3-leaf stage of corn, and mixed with dicamba, imazethapyr and clethodim, it can reduce the phytotoxicity of herbicides to corn and promote the growth of corn; The mixed use of mesotrione and nicosulfuron can not only improve the control effect of herbicides on weeds, but also promote the growth of corn.

Zeatin:

Seed soaking treatment with 0.0067~0.01 mg/L for 12~24 h can promote the formation of chlorophyll and enhance the photosynthesis of crops, thereby promoting the growth and resistance of seedlings.

DCPTA:

Soaking with 15~20 mg/L DCPTA liquid for 7 hours before sowing or spraying 50 mg/L DCPTA in 2 leaves and 1 heart stage of seedlings can increase the activities of 3 antioxidant enzymes (SOD, CAT and POD) in leaves of maize seedlings , significantly increased soluble sugar, soluble protein content and DPPH reactive oxygen species scavenging efficiency in maize seedling leaves, reduced MDA content in leaves, promoted cell membrane integrity, and improved maize drought resistance.
