不同生长调节剂对番茄侧枝水培扦插效果试验

摘要

以瑞克斯旺409番茄侧枝为试材，研究了布洛芬、萘乙酸、吲哚美辛、吲哚乙酸、绿神等5种不同生长调节剂对番茄侧枝水培扦插生根的影响。试验结果表明，绿神、萘乙酸、布洛芬处理的番茄侧枝，可缩短生根时间、促进根系生长、提高根系活力；生根效果最好的是绿神，萘乙酸和布洛芬次之，吲哚美辛和吲哚乙酸较差。%Taking Rijk Zwaan 409 as material, we studied the effects of five different growth regulators (ibuprofen, NAA, indomethacin, IAA, DA-6) on rooting of tomato lateral branch cuttings in water culture condition. The results showed that, the three treatments DA-6, NAA and ibuprofen could shorten the rooting time, promote the root growth and improve the root activity. The the growth regulator Lvshen (DA-6) had optimal rooting effect, and NAA and indomethacin took the second place, while indomethacin and IAA had the poorest effect on promoting the root growth of tomato lateral branch cuttings.
