Response of in vivo propagation techniques for Viola pilosa on growth and flowering behaviour

Abstract

In vivo propagation of Viola pilosa, an ornamental plant renowned for its medicinal properties, is essential for understanding the impact of various vegetative propagation techniques (from cuttings, runners, etc.) or seed germination, on its growth and flowering potential. This study evaluates the growth and flowering responses of Viola pilosa propagated through different methods: mother plant, cuttings, runners, and seeds. The study focuses on various growth parameters such as petiole length, lamina size, flower size, rosette diameter, tillers per plant, leaves per plant, and flowering characteristics, including flower count, flower weight, and flower yield per plant. Results suggest that different propagation methods significantly affect the growth and flowering behavior of Viola pilosa, with runners and mother plants showing superior performance in several traits.These propagation methods are more cost-effective as they require less specialized equipment and facilities andare less time-consuming than in vitro propagation for large-scale multiplication. These methods also ensure the new plants are genetically identical to the parent plant for maintaining desired traits like yield or any specific characteristics, making them more accessible for farmers and researchers with limited resources.
