CRUZ ROMERO, Wendy et al. Production of vegetable seedlings with Azospirillum sp. and foliar spray with bee honey. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.1, pp.59-70. ISSN 2007-0934.

With the goal of proposing biotechnology for the sustainable production of vegetable seedbeds, broccoli (Brassica oleracea. Italica Group), onion (Allium cepa L.), lettuce (Lactuca sativa L.), and tomato (Solanum lycopersicum L.) seedlings were evaluated as nutrition alternatives, inoculated with 7A and AMRp10 strains of Azospirillum and foliar spray with 2% bee honey (AFMA) to determine the effect on height, leaf area, stem diameter, dry weight, SPAD units and bulb diameter (onion). The experiment was done in greenhouse conditions using a completely random design and the experimental units used were commercial seedbeds with a mixture of peat moss and pearlite as a substrate. The results indicate that the foliar spray with 2% bee honey significantly increased the height (13%), foliar leaves (38%) and dry weight (30%) of broccoli seedlings. In lettuce seedlings, the height and the leaf area were greater with A. AMRp10 in 18 and 98%, respectively. Furthermore, height increased 23% in tomato seedlings with A. AMRp10. On the other hand, with the inoculation of A.7A, SPAD units increased 7% in the broccoli seedlings when compared to the AFMA treatment and the stem diameter increased 11% compared with A. AMRp10. The leaf area of the tomato seedlings also increased 52% with regards to the A.AMRp10. In this research, the inoculation of the 7A strain of Azospirillum and foliar spray with bee honey showed to have developing effects on plant growth; therefore they constitute a promising and feasible alternative for the production of vegetable seedlings.
