Effects of Different Treatments on Bulb Induction from Lily Scales Cutting
In order to enrich the lily cutting propagation technology system and select suitable cutting treatment combinations,the new lily va-riety"Jiaoyang"was used as the experimental material to explore the effects of different substrate ratios and fertilizer treatment combinations,plant growth regulator types and concentrations,and scale position on its scale cutting.The results showed that pure perlite was more condu-cive to the formation of bulblets,while pure vermiculite was more conducive to the development of bulblets and the growth of root system at the later stage;The optimal substrate ratio and fertilizer combination is pure vermiculite+water-soluble fertilizer treatment,which generates more small bulbs with the largest diameter,the largest number of roots,and the longest root length;The outer layer of scales is conducive to the for-mation of small bulbs,while the outer layer of scales is conducive to the development of small bulbs and the later growth of root systems;The cutting rooting effect of IBA is better than that of NAA;The optimal combination of scale position and growth regulator is middle scale+IBA 200 mg/L,which generates more small bulbs with a larger diameter and the largest number of roots.The research results have laid a technical foundation for the ball propagation of the new lily variety"Jiaoyang".
