Effects of different combinations of growth regulators on the in vitro growth parameters of Poncirus trifoliata L. (Raf.)
Abstract
In this study, an in vitro propagation protocol of Poncirus trifoliata L. (Raf.) rootstock, which is one of the main rootstocks used in citrus, was created. Monocular node parts of the plant, which is the source of explant, were cultured in MS nutrient media containing BAP at dissmilar concentrations (0.5-1.0-2.0 mg/l). Afterward, it was observed that shoot appearance and tillering were achieved in the node explants cultured in MS nutrient medium comprising 1.0 mg/l BAP. The shoots were removed to a new culture in MS nutrient media containing NAA and IBA for rooting. While 30% rooting was achieved in the rooting medium, 62% of the rooted plantlets were acclimated to external conditions. 2 mg/l BAP and 2 mg/l silver nitrate (AgNO3) doses were supplied to the MS medium. The results of this study were obtained and a compound was found to the yellowing and leaf fall problem. As a result, in vitro propagation of Poncirus trifoliata, which is among the important citrus rootstocks, was tried, and its rooting ability was investigated in different nutrient media concentrations after shoots were obtained from different explants.
