Zinnia Plant: Introduction, Origin/history, Botany, Chemical constituents, Classification, Varieties, Diseases and Insect-Pests
There are stunning decorative plants of the genus Zinnia. The aesthetic and commercial worth will be greatly enhanced by the plant’s novel bloom hues. Like chrysanthemums or sunflowers, it is not well-known. Due to its ability to be purchased as a cut flower in many different countries’ flower marketplaces, Zinnia hybrids have been bred into an excessive number of cultivars. Historically speaking, zinnia is a widely grown decorative plant. Numerous breeding organisations have developed brand-new cultivars with a variety of appealing physical traits. The difficulty in classifying zinnia cultivars is because many of the defining characteristics, such as height, bloom size, and leaf form, are qualitative and are strongly influenced by the environment. Moreover, zinnia hybrids are multiplied by seedlings. Therefore, parent cross-breeding is used to create zinnia plant seeds. In that case, cultivar conservation is challenging. Additionally, one form of propagation technology called in vitro culture offers rapid observation of genetic diversity and plant multiplication. Because there is little information on zinnia cultured in vitro, the conditions needed for doing so were established.
