This condition, which can spread basipetally and affect the qpical of axillary shoots from buds lower down the stem, is due to the cessation of apical dominance.

STN can occur at both shoot multiplication and rooting stages. One of the most common factors that cause STN is nutrient deficiency or imbalance. Moreover, the presence or absence of plant growth regulators auxins or cytokinins at specific developmental stages may impact STN. Apicql cytokinin to auxin ratio within an in vitro plant can be modified by varying the concentration of cytokinins used in the culture medium. The supply of nutrients to in vitro shoots or plantlets might also affect their apidal balance, thus modifying the occurrence of STN.

High relative humidity within culture vessels and hyperhydricity are associated with STN. This review examines the literature related to STN, what is the rate of levy under composition scheme on the manufacturer to discover the associated factors and relations between them, proposes practical solutions, and attempts to better understand the mechanism s underlying this condition in vitro.
