Smearing apical point with a mixture of 0.2% colchicine plus adeps lanae and 1.5% DMSO was also effective with doubling frequency 14.0%. Dripping the apical point of plantlets with trifluralin has also been tested, and it showed effective in inducing tretraploid from double haploid, but obviously delayed plant growth.

本试验还用具有抗微管形成的除草剂氟乐灵进行黄瓜幼苗滴苗加倍试验，试验结果表明，在进行黄瓜双单倍体诱导纯合四倍体时，氟乐灵具有使染色体加倍的功能，但同时也具有延迟处理植株生长的作用。
