Rooting of Lemon (Citrus limon L.) Stem Cuttings as Affected by Different ANAA Concentrations

Abstract

The study was conducted at the Pomology Project, Department of Horticulture, College of Agriculture, Benguet State University, La Trinidad, Benguet from January to April 22, 2016 to determine the effect of different ANAA concentrations on the rooting of lemon stem cuttings; to determine the best stem cuttings of lemon and the best concentrations of ANAA that would enhance uniform rooting and seedling growth of stem cuttings; and to determine the profitability of using ANAA in producing seedlings of lemon from stem cuttings. Highly significant differences were observed on the percentage survival, percentage of rooted cuttings, shoot length, number of leaves developed before transplanting and seedling vigor of the lemon cuttings as affected by the kinds of stem cuttings. Significant differences were also observed on the average root length of cuttings. However, there were no significant differences observed on the number of days from sticking to visible root formation and average number of roots produced per cutting. Result shows that there were no significant differences observed on the parameters on lemon cuttings as affected by the different ANAA concentrations except for the seedling vigor wherein highly significant differences was observed. Significant differences were observed on the percentage survival and percentage of rooted cuttings as affected by the combination effects of the kinds of stems cuttings and ANAA concentrations on the cuttings of lemon. However, no significant differences were observed on the number of days from sticking to root formation. Based on the results, it is therefore recommended to use shoot tip cuttings of lemon treated with 250 ppm ANAA concentration because it was observed to have attained the highest percentage survival and percentage of root development.
