Plant conservation strategies are important to support the development of livelihoods based on the sustainable uses of plants and promote the understanding and sharing of the benefits and functions of plants. Botanical gardens allocate most of their resources to plant conservation and the development of educational activities such as making plant species diversity known to the public. These gardens can also play an essential role in human well-being and provide in human needs. In this article, we review the history of the development of Kirstenbosch National Botanical Garden and the development of other national botanical gardens in South Africa. We will discuss conservation through cultivation, discovering and documenting diversity of plants, indigenous plants, threatened plants, medicinal plants, extinctions and rediscoveries, environmental education, conservation science, citizen science, horticulture, research and creating a haven for biodiversity. Future challenges and responsibilities of botanical gardens will be discussed including in situ and ex situ cultivation, promoting awareness, creating partnerships, increasing capacity building and training activities, sharing information and making gardens sustainable.展开更多

It considers that seclusion sentiment of landscape is generally created through rockeries, waters, plants disposition, landscaping buildings and pavements, paintings and carvings.展开更多

Monoecious fig species and their pollinating wasps are in conflict over the use of fig ovaries which can either produce one seed or one wasp. From observation on Ficus virens Ait., we showed that female flowers with outer layer of ovaries (near to the wall of syconium) had no significant difference from that with inner and interval layer of ovaries (near to the syconium cavity), in which most seeds and wasps were produced. This meant that fig tree provided the same potential resource for seed and wasps production. Observation indicated that there was usually only one foundress in syconium at female flower phase and no com- petition pollinators. Measurement of the style length of female flowers and the ovipositor of pollinators indicated that most ovaries could be reached by pollinator’s ovipositor. However, at the male flower phase, production of seeds was significantly more than that of wasps including non-pollinating wasps but there was no significant difference between seed and pollinating wasp production when without non-pollinating wasps produced. This result indicated that non-pollinating wasps competed ovaries not with seeds but with pollinating wasps for ovipositing. Bagged experiment showed that the sampling fig species was not self-sterile which was important for figs and wasps to survive bad season. Seed production in self-pollinated figs was not significantly different from total wasps in- cluding non-pollinating ones. This might be related with the weaker competition among wasps since bagged figs were not easy to reach by wasps from outside.展开更多
