Inhibit wheat ear/seed germination
Application of regulators to inhibit wheat ear/seed germination
Paclobutrazol
Applying 15g of paclobutrazol 27d before wheat mature, the control effect on ear germination at 7d and 11d after wheat maturity can reach 78.24% and 53.85% respectively, and has little effect on grain weight.
Chlorhexidine
Applying 150 g of chameleon 20d before the wheat matures, the control effect on the ear germination at 7d and 11d after the wheat matures can reach 58.04% and 32.33%, respectively, with little effect on the grain weight.
Mepiquat chloride
Applying 6.25 g of mepiquat chloride 27d before the wheat matures, the control effect on the ear germination of the wheat at 7d and 11d after maturity can reach 67.99% and 24.75% respectively, but it has a great impact on the thousand-grain weight.
Allocin and Salicylic Acid
The seeds were soaked with 70mg/L, 140mg/L and 200mg/L inducine solution for 6 hours respectively. The exogenous inducin had a certain degree of inhibitory effect on seed germination, and showed a dose effect that the higher the concentration, the stronger the inhibitory effect, and the highest inhibitory effect. The effect can reach 74.67%. The compounding of 70 mg/L inducine and 1100 mg/L salicylic acid significantly inhibited the germination of seeds, and had significant effects on different varieties of wheat such as "Kenong 199", "Nei 8" and "Xiaoguan 54". The germination-inhibiting effect of alloanthin alone was closely related to cultivar genotype.
