Propagation of Saccharum repens Willd.

Saccharum repens Willd., commonly known as creeping sugarcane, can be propagated through vegetative methods such as stem cuttings, rhizome division, and tissue culture.

Stem cuttings

Stem cuttings are taken from mature and healthy plants during the growing season. The cuttings should be about 10-15 cm in length with at least two nodes. The lower leaves are removed, and the cutting is planted horizontally in a well-draining potting mix. The cutting should be kept moist and in a warm and humid environment until roots and new foliage emerge.

Rhizome division

Rhizome division is a common method used for clump-forming grasses such as Saccharum repens. The plant is lifted, and the rhizomes are divided into smaller sections with at least one new shoot and roots. The sections are planted in a well-prepared soil mix and watered regularly to establish new roots.

Tissue culture

Tissue culture is a method used for large-scale propagation of Saccharum repens and other plants. It involves taking a small piece of plant tissue, such as a leaf or stem segment, and placing it in a nutrient-rich medium. The tissue develops into a callus, which is transferred to another medium to stimulate shoot and root growth. The resulting plantlets are then transferred to soil for further growth and development.
