However, in recent times, ornamental lianas have also been used for vertical landscaping in residential buildings. Today, many lianas occupy a leading position among plants, due to their landscape features, such as the colorfulness of flowers, the variety of leaf shapes, and their aroma. The practice of growing flowers in Uzbekistan dates back to ancient times. Floriculture came to our republic through the Great Silk Road from China, Egypt, and India. Because of this, ornamental plants have been widely used for landscaping in cities such as Samarkand, Bukhara, Khiva, Shahrisabz, Kokand, and Margilan. Nowadays, perennial lianas are planted on the grounds of the Botanical Garden at Samarkand State University, and collections of these plants have been created. The garden area contains various species of lianas, including Lonicera japonica Thunb, Clematis florida Thunb, Parthenocissus quinquefolia (L.) Planch, Parthenocissus inserta (A.Kern) Fritsch, Hedera spiral L, Hedera canariensis Willd, Campsis radicans L, Wisteria sinensis (Sims) DC, Actinidia chinensis var. deliciosa (A.Chev.), Humulus lupulus L, Aristolochia clematitis L, and several varieties of Rosa canina L. such as Golden Celebration, Paprika, Aspirin, Burgund, and Rosarium Uetersen.展开更多

The quantities of plant leaf area for the other 17 ornamental plant species on these squares were directly measured, and the total quantity of plant leaf area of each studied square was obtained individually. The results showed that the quantity of plant leaf area on Shengli square with ornamental plants structure composed of arbor tree species, shrub tree species and turf grass was highest among the three squares. It is believed that the design model of multi-storied vertical structure and proper tending of plant community could not only increase the quantity of plant leaf area, but also play an important role in generating ecological and landscaping benefits. Some corresponding suggestions were put forward on the basis of comprehensive analyses on the plant leaf area quantity of the three representative squares in Kunming urban area.展开更多

[Method] The phenotypic characteristics and germination rate of the seeds of four excellent lupin pedigrees were measured, and then their correlations with seeding growth were analyzed. [Result] There were abundant variations among the four ornamental lupin pedigrees. Pink seeds had the largest volume and red seeds had the largest 1 000seed weight. The variation coefficients for the seed morphological traits among the four pedigrees ranged from 2.97% to 14.34%. Seed specific weight and 1 000-seed weight could be used as important indicators for selection in breeding because of their higher variability. Seed weight variation of ornamental lupin was mainly depen- dent on seed width variation. There was small variation in seed length. The seeds of the four ornamental lupin pedigrees started to germinate one day after sowing, and the germination period was 5 d. Germination rate coefficient and germination index of pink and red seeds were higher than those of blue seeds, but blue seeds had the largest germination rate. 1 000-seed weight shared significantly positive correlations with seed germination rate, germination potential and seedling retention rate. Round and large seeds had some advantages in germination. Full seeds had higher germination rate and speed, and seedling retention rate. There was a significant relationship between seed length-width ratio and the number of leaflets of seedlings. [Conclusion] The results provided references for the evaluation of seed phenotypic diversity and breeding research of ornamental lupins.展开更多

The result showed that autumn and winter landscape plants in Kuitun City were primarily evergreen coniferous and deciduous trees outstanding for their shapes and colors, and that landscape was created through different types of plant disposition. Especially colors of trunks, barks, leaves, winter buds and fruits' colors provided favorable conditions for appreciating plants in autumn and winter. Finally, suggestions were proposed according to the investigation and analysis of autumn and winter ornamental plants in Kuitun City, so as to provide reference for future construction and development of landscape plants.展开更多
