[ Method ] Self-crossing and crossing by inbreeding of more generation female parent, male parent ：07-10-2-3-3（ tall spherical, golden yellow peel with thin lines, red flesh）, 07-32-2-3-5（ tall spherical, green peel with greenish thick lines, red flesh）, 07-33-1-2-3（tall spherical, green peel with greenish thin lines, red flesh） [ Result] It was found that Fo （07-10-2-3-3 × 07-32-2-3-5） and Fo （07-10-2-3-3 × 07-33-1-2-3） seed ripening was accelerated, and the sugar degree increased by 1.7 - 2.4%, and the flesh became crisp.[ Conclusion] The result demonstrates watermelon has xenia effect.展开更多

[Method] Three hightoil maize varieties were cultivated to pollinate three common maize varieties. [Result] The kemel yield of common maize was increased or changed slightly, and the embryo weight was increased significantly after they were pollinated with the pollen of hightoil maize. The kemel embryo percentage and protein content of common maizethigh oil maize hybrids were higher than those of common maize inbreds. [Conclusion] The growth and development of kernel embryos, as well as the kernel quality of common maize was improved by pollination with hightoil maize.展开更多

Although the cultivation of the tung tree produces great economic value, some important genetic and physiological traits in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;"> have not been fully recognized. As one of them, the effect of pollen on the maternal plant (xenia) is unknown in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;">, which is an important part of the efficient cultivation system of many crops. This study performed hybridization with three important tung cultivars (Dami, Xiaomi and Putao) to evaluate the influence of pollen source on fruit and seed development. The results revealed that xenia is present in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;">, which influences fruit setting, fruit size, seed weight and oil content. Among the cultivars investigated, the hybridization combination with Putao as a female parent and Dami as male parent showed significant improvement of seed yield and oil content than self-pollination, which could be considered to apply in practice.展开更多

For a period of two decades, it developed the hotel buildings＇ substructure, a project known as the ＂Xenia project＂. During this period, Greek architects, devoted to modernism, designed and supervised 53 hotel compounds, which spread throughout the country. Today, the Xenia Hotels are internationally recognized as part of Greece＇s modern cultural heritage, based on the simplicity, the definition of the form and the truth in materials use, besides the integration of the buildings in the natural environment, components which reveal themselves as a unique venture. This paper aims to reveal that, despite the efforts to retain the Xenia Hotels, these procedures remain incomplete. They rightly focus on architectural shells, morphological and functional standardization, proper utilization of the Greek environmental conditions, and the use of authentic local materials. However, the cultural evaluation of these settlements can only be completed by their holistic design, which also comprises their interior spaces, lightening and furniture design, all these detailed aspects that form an organic entirety and which are not included in these efforts.展开更多

To further understand this phenomenon,we investigated the xenia effect in Castanea henryi using the cultivars ‘Huali 1', ‘Huali 2', ‘Huali 3', and ‘Huangzhen' as materials. Twenty combinations of self-, cross-, and natural pollination were undertaken in a chestnut orchard in Chenzhou City, Hunan Province, China. Significant differences were observed among the pollination combinations in terms of the time of fruit ripening, rate of fruit setting, size of the barbed shell and nut, and content of soluble sugars, fats, proteins, amylose, and vitamin C. No significant differences were observed with regard to nut rate,content of total starch, and moisture content. The fruit quality of the 20 pollination combinations was evaluated using a subordinate function method,and showed that Huali 2 × Huali 3 was the best combination, and Huangzhen × Huangzhen was the most ineffective combination. Therefore, we recommend the combination of Huali 2 × Huali 3 for the future production of C. henryi.展开更多
