Morphological and biochemical aspects of propagated rose by stenting technique as affected by rooting substrate

Rose growers around the world propagate rose by stenting, a method of propagation that combines grafting and cutting in one action. The resulting plantlet is called a stentling. Their morphological and biochemical aspects of stentlings were investigated in different rooting substrates (40% perlite + 60% cocopeat, 50% perlite + 50% cocopeat, and 70% perlite + 30% cocopeat). Comparison of substrate treatments revealed that the highest root number, fresh and dry root weights, flavonoid contents, and carbohydrates of shoots were obtained in 70% perlite + 30% cocopeat substrate, and the greatest root length and volume were found in 50% perlite + 50% cocopeat substrate. The highest fresh and dry shoot weights, shoot length, leaf number, leaf area and success percentage of transplanted cuttings, leaf chlorophyll content, and total phenol and carbohydrates of the graft union were obtained in 70% perlite + 30% cocopeat and 50% perlite + 50% cocopeat substrates. The main results showed that the morphological and biochemical characteristics of the stentlings depend on the mixture of rooting substrate and that the stentlings with the best properties were grown in the 70% perlite + 30% cocopeat substrate.

Automated summary

The morphological and biochemical characteristics of rose stentlings were investigated in different rooting substrates. The results showed that the stentlings grown in the 70% perlite + 30% cocopeat substrate had the highest root number, fresh and dry root weights, flavonoid contents, and carbohydrates of shoots. The substrate of 50% perlite + 50% cocopeat resulted in the greatest root length and volume.
