[Method] An introduction trial on 42 varieties with colored foliage was conducted, in which major ornamental characteristics, phenological phases and stress resistance of all the introduced plants with colored foliage were observed and the introduced plants were comprehensively evaluated. [Result] Golden-and Compound-leaved Maple, Red-leaved Sakura, Pink-and Compound-leaved Maple, Amur Maple, Purple-leaved Canadian Redbud with good performance were selected preliminarily, which can be applied for landscape in Zhengzhou area. Among them, Golden- and Compound-leaved Maple, Golden- and Silvery-leaved Maple and Purple-leaved Smoketree can either be planted separately, or in a line as boulevard trees, or in groups as ornamental forest; Red-leaved Sakura, Pink- and Compound-leaved Maple and Purple-leaved Canadian Redbud can be planted in groups or separately in gardens, parks or alongside streets or in front of buildings; Amur Maple with high adaptability is a excellent tree species for afforesting barren mountain. [Conclusion] This study has not only provided new excellent germplasm sources for the landscaping in Zhengzhou area, thus favoring the improvement of local landscaping level, but also provides examples and references for the introduction of plants with colored foliage in the other areas.展开更多

Within this region a total area of 26 000 ha have been identified through climate matching as suitable and a further 63 000 ha potentially suitable for environmental plantings of P. radiata. The plantations are being established in widely separated small patches on steep and degraded slopes along the dry river valley The newly introduced P. radiata are exposed to two kinds of forest health risks： they may be attacked by （a） indigenous pathogens and pests against which they may not possess any resistance or （b） by inadvertently introduced foreign pests or pathogens. This paper presents a survey of the potential damaging pests and a preliminary assessment of forest health risks facing the P. radiata plantations over a much longer timeframe than the initial phase of introduction and early plantation establishment. An empirical appmach was adopted to evaluate forest health risks by a combination of literature review, examination of historical records of pest and disease outbreaks in the surrounding conifemus forests, field surveys and inspections, specimen collection and identification, and most importantly, expert analysis of the likelihood of attack by specific pests and pathogens and the subsequent impact of such attacks. The assessment identified some specific forest health risks to the long-term success of P. radiata introduction in this area. These risks are closely associated with the indigenous pests and pathogens of the two native pine species, P. tabulaeformis and P. armondii since these pests and pathogens are considered more likely to establish on P. radiata over time. Exotic pests and pathogens are of a quarantine concern at present. Based on the results of assessment, recommendations are pmvided to improve forest vigour and to reduce the forest health risks posed by indigenous as well as exotic pests and pathogens to the introduced P. radiata. Ways to increase the ability to manage the forest health risks once a particular pest infestation and disease eventuates are also recommended. Although detrimental to the survival and growth of the introduced P. radiata, the impact of identified forest health risks are not considered to be fatal to the long term success ofP. radiata in this area.展开更多

In 1979, scions were introduced into China and were grafted in Wuchang of Hubei, Chenggu of Shaanxi, Santai and Xichang of Sichuan, and Kunming of Yunnan. Its fruit is oval, and the weight of a single fruit is 5.38 g. The top of fruit is rounded, and stigma exists. The base of fruit is flat. There is a mouth on the top of its fruit, and it is asymmetric. Oil content in fresh fruit is 24.69%, and oleic acid content is 77.5%; the oil quality is good. In the areas with cold winter in dry and hot valleys of the Jinsha River in Yunnan, its fruit matures in late September. In 2016, it was approved to be a good variety by Yunnan Forest Tree Variety Examination and Approving Committee.展开更多

[Method] The Elaeagnus angustifolia L. from Ningxia Province were sown in nursery and practice base of Forestry College in Beihua University to observe their phenophase, growth state, stress resistance and study the relations between survival rate and different cutting medium, grafting methods. [Result] Elaeagnus angustifolia L. could adapt to climate condition in Jilin area and grow well . Among 3 cold-proof measures, there was no freezing injury by soil burial method, although there was 2.8% and 3.9% mortality by covering grassy marshland and winding straw, the cold injury degree was light, so they could go through winter normally. Meanwhile, Elaeagnus angustifolia L. had good saline-alkali tolerance, drought resistance and flood resistance. The successful cutting and graft of Elaeagnus angustifolia L. provided a condition for planting in large-scale and knew the rooting rate of different cutting medium. [Conclusion] Elaeagnus angustifolia L. could be introduced to plant in West Jilin Province.展开更多

INGER focuses onworldwide exchange, evaluation and utilization of improved varieties and elite breedinglines of rice. China has actively participated in the activities of INGER since 1980.During the pasted years, 26500 INGER entries with diversity genetic background have beenintroduced and evaluated by Chinese scientists. Among of them, 37 commercial varietiesdirectly from elite INGER entries and 27 rice hybrids using INGER lines as their restorerlines/donors have been released to farmers in China. About 1900 INGER entries wereindirectly utilized as cross parents or pest resistant donors in various national andprovincial rice breeding programs. Based on the incomplete statistics, there were 14.5million cumulated hectares planting these varieties and hybrids, from which 5.44 MT ofincreased rough rice has been received by farmers. INGER accelerates the transfer ofadapted varieties and hybrids to farmers, and increases the diversity of rice germplasmin cultivation. Therefore, INGER cooperation has made great benefit both in economy andsociety in China.展开更多
