Vegetative Reproduction through Green Cuttings of the Introduced Form <i>Weigela florida</i>f. “<i>Bristol ruby</i>” (Caprifoliaceae) in the Conditions of the Tashkent Botanical Garden (Uzbekistan)

For the first time, work was carried out on the vegetative reproduction of Weigela florida f. “Bristol Rubru” (Caprifoliaceae) was introduced into the Tashkent Botanical Garden (Uzbekistan) through green branches. As a result of the research conducted, it was noted that the vegetative reproduction possibilities of the “Bristol Ruby” form of Weigela florida were high. When placed on stimulants of two types (kornevin, heteroauxin), it became known that kornevin stimulants are effective in taking root. It was found that the effective way to multiply this form by green branches in a vegetative way—when placed on the stimulator of kornevin from the middle part of the rod, the indicators of root extraction of the cuttings were 93.3%, which is more effective than other options. When vegetative reproduction of this decorative form, it is recommended that the seedlings come to the standard state in 3 - 4 years and the root extraction indicators are high—this is its use as the second row shrubs in the case of growing on strongly saline soils in the conditions of Uzbekistan. The cultivation of green cuttings of the form in the fog showed that they are more effective than in the open ground.

Botanic gardens should lead the way to create a "Garden Earth" in the Anthropocene

The strength and expertise that botanic gardens bring to conservation are based on their detailed knowledge and understanding of the care. management, and biology of a diversity of plant species. This emphasis on the organism has led to many ex-situ and in-situ conservation programs aimed at protecting endangered species, restoring threatened populations, and establishing living plant and seed collections of endangered species. In China, the scale and pace of change in land and resource use, often leading to environmental degradation, has created a strong emphasis on improving environmental conditions. If done properly, being "green" can be a surprisingly complex issue, because it should encompass and exploit the whole of plant diversity and function. Unfortunately, 'green' often includes a small portion of this whole. Earth's rich plant diversity presents considerable opportunity but requires expertise and knowledge for stable and beneficial management. With the dawning of the Anthropocene, we should strive to live on a "Garden Earth", where we design and manage our environments, both built and natural, to create a healthy, beneficial living landscape for people and other organisms. The staff of botanic gardens worldwide and the living collections they maintain embody the best examples of sustainable, beautiful, and beneficial environments that thrive on plant diversity. This expertise should be a fundamental resource for agencies in all sectors responsible for managing and designing "green" infrastructure. Botanic gardens should actively engage and contribute to these opportunities, from large public infrastructure projects to small private conservation efforts. Here, we discuss several ongoing conservation efforts, primarily in China, and attempt to identify areas where botanic gardens could make a significant and meaningful difference.
