目的:探讨抑制剂多效唑、氯苯胺灵及多效唑与氯苯胺灵的组合配方对姜黄根茎常温贮藏期间抑芽效果的影响,筛选出一种简单有效的抑制姜黄根茎发芽的试剂,为姜黄根茎的安全贮藏提供参考。方法:以川产道地姜黄品种为供试材料,设置不同浓度的多效唑、不同剂量的氯苯胺灵及二者不同配比的复合配方处理姜黄根茎,测定影响抑芽效果的相关形态和生理指标。结果:与CK相比,各处理组均有不同程度抑制根茎发芽的效果,减少了重量的损失,POD活性、可溶性蛋白含量均得到提高;复合剂多效唑+氯苯胺灵对根茎的抑芽效果好于单剂多效唑或氯苯胺灵。结论:综合姜黄根茎的抑芽效果、重量损失率、品质变化等因素,以选用多效唑与氯苯胺灵的复合配方作为姜黄根茎的抑芽剂比较理想,推荐使用的剂量为25 mg/L多效唑+4 g/kg氯苯胺灵。
OBJECTIVE: To investigate the effect of combination of paclobutrazol, chloramphenicol and paclobutrazol and chloramphenicol on inhibiting germination of turmeric rhizome at room temperature, and to screen out a simple and effective agent for inhibiting the germination of rhizome of turmeric Storage for reference. Methods: The rhizomes of turmeric were treated with different concentrations of paclobutrazol, different doses of triflumuron and the compound prescriptions with different dosages. The relevant morphological and physiological indexes of the turmeric were determined. Results: Compared with CK, the treatment groups had different degrees of inhibition of rhizome germination, reduced weight loss, POD activity and soluble protein content, and the effect of compound paclobutrazol and chloramphenicol was better than that of CK In single-dose paclobutrazol or chloroaniline. Conclusion: Based on the inhibition effect of curcuma longa rhizome, the rate of weight loss and the change of quality, the combination formula of paclobutrazol and chloramphenicol is ideal as the suppository of rhizome of turmeric. The recommended dosage is 25 mg / L paclobutrazol + 4 g / kg Chlorpheniramine.
