Reasons for the Disappearance of the Golden Edge in Sansevieria Kerchoviana Cuttings
The editor provides netizens with the knowledge of flower cultivation, introducing the information about Sansevieria Kerchoviana, including the reasons for the disappearance of the golden edge in its cuttings. The details are as follows:
Once Sansevieria Kerchoviana is propagated through cuttings, the resulting seedlings often lack the most striking golden edge, as it is a very special type of chimeric color stripe that cannot be inherited unconditionally.
The chimeric color spots are different from nuclear genetic color spots, such as the white stripes on watermelon peperomia, which can be stably inherited through cuttings or tissue culture. They are also different from cytoplasmic genetic color spots, such as the common variations in chloroplasts found in geraniums, leading to leaves with green and white patterns, which are also relatively stable and can be obtained through cuttings. They are even more different from the inheritance of non-chimeric color spots, such as the patterns on the leaves of cold water plant and spotted begonia, which are caused by the separation of epidermal cells on the lower side of the leaf palisade tissue, forming bubble-like structures that show color differences under scattered light. Since they are genetically homogeneous, the patterns on the seedlings will not disappear whether through cuttings or tissue culture.
The inheritance of chimeric color spots is relatively complex. Among them, chimeric patterns are relatively stable, while marginal chimeras and marginal distinction chimeras are prone to interlayer replacement and bud position changes, showing instability in color spot traits, just like the leaves of Sansevieria Kerchoviana, where the center is green and the sides are golden yellow. The golden edge comes from镶嵌 variation. The cells in the patterned area after variation have different genetic properties from the original green part. Therefore, the small plants regenerated from the green part have green color, while the plants regenerated from patterned leaves have the golden edge disappear. The fundamental reason is that the cells in the yellow part do not contain chlorophyll, and their ability to produce nutrients through photosynthesis is poor, far below that of the green tissue, resulting in interlayer replacement.
In view of this, if you want to obtain Sansevieria Kerchoviana plants with stable golden edge traits, you can only use the division method for propagation.
The above comprehensive explanation of the reasons for the disappearance of the golden edge in Sansevieria Kerchoviana cuttings is shared, hoping to help you.
