Abstract:
Potato onion (Allium cepa var.agrogatum Don.) was used as raw material to determine the effects of six mineral nutrition deficiencies (N，P，K，Ca，Mg，Fe) and indolebutyric acid on roots growth of the potato onion by hydroponic culture and split-root method，in order to provide scientific basis for rational fertilization on potato onion and plant root development theory.The results showed that the roots length of potato onion in N，K，Ca deficiency treatment were significantly lower than those in the total nutrition，P deficiency had little effect on root elongation，however，Mg and Fe deficiency promoted root elongation.Furthermore，the number of roots were significantly less in the N and K deficiency treatment than that in the total nutrition，however，other elements had no significant effects on roots number.The number of lateral roots in N，P，Ca，Mg and Fe deficiency treatment were significantly higher than those in the total nutrition，respectively.The number of lateral roots in N deficiency treatment was much higher than that in the total nutrition and other elements deficiency treatment，while the number of lateral roots in K deficiency treatment was zero.When the concentration of indolebutyric acid was 10 mg?L-1 and 15 mg?L-1，the roots length of potato onion were significantly longer than that of 0 mg?L-1，and the higher the concentration，the longer the root length.Split-root trial showed that the lateral root number of potato onion in P deficiency solution was significantly more than that in the total nutrition，indicating the response of potato onion roots to P heterogeneity was mainly localized.
