(2016): Influence of Organic Fertilizers on Physiological Quality and Rooting of Snapdragons (Antirrhinum majus)

In this study, the effects of organic fertilizers on internal quality and rooting of snapdragons (Antirrhinum majus) were investigated. Seedlings of xxxWhite Rocketxxx, xxxRocket Goldxxx, xxxOrchidxxx, xxxRed Stonexxx and xxxRed Rocketxxx species were transplanted into 12 L pots filled with 1:1 sand: soil mixture at the beginning of March 2011. Two different liquid biological fertilizers were used. The first one is the Effective Microorganisms (EM (R)) consisting of lactic acid bacteria (Lactobacillus casei and Lactobacillus plantarum), photosynthesis bacteria (Rhodopseudomonas palustris) and fermentation bacteria (Saccharomyces cervisiae); the second one is Rhizo Vital 42 (R) consisting of Bacillus amyloliquefaciens bacteria. The physiological quality of the petals was investigated. With regard to petal P-dissipation values, while EM treatments yielded almost identical results with the control treatment, Rhizo Vital 42 treatments had lower yield values than the control treatment. Both organic fertilizer treatments improved rooting and effects of EM treatments on rooting were found to be significant. Biophoton measurements were also performed over the petals and photoluminescence values of fertilizer treatments of all species were found to be lower than the control plants. In other words, organic fertilizer treatments improved the quality by decreasing the stress levels in petals. (C) 2016 Friends Science Publishers
