[Objective] In order to provide a bas is for the development and utilization of excellent germplasm resources of wild kiwifruit in Yunnan Province, the sensory traits, morphological indicators, nutrient contents and nutritional quality of excellent germplasm resources of wild kiwifruit were comprehensively comparative analysis in this paper. [Method] The selection criteria were established with the objectives of large fruits, hairless or less hairy, and high quality, and the 'LB-2', 'LBBH-1 ' and 'XSD-1' were selected through the evaluation of sensory and morphological indexes, and their total sugar, total acid, vitamin C and soluble solids contents were determined and analyzed. According to the evaluation method of quality comprehensive index, the nutritional quality of 3 excellent germplasm resources was compared and analyzed with the cultivar 'Yunmi No. 1'. [Result] The order of fruit longitudinal diameter was 'XSD-1' > 'LB-2' > 'LBBH-1', and the difference between 'LB-2', 'LBBH-1' and 'Yunmi No. 1' were significant. The order of fruit transverse diameter was 'LBBH-1' > 'LB-2' > 'XSD-1', and the differences between the three excellent germplasm resources and 'Yunmi No. 1' reached a significant level. The order of fruit lateral diameter was 'LBBH-1' > 'LB-2' > 'XSD-1', the differences between the three excellent germplasm resources were not significant but reached a significant level with 'Yunmi No. 1'. The fruit weight per fruit was in the order of 'LBBH-1' > 'XSD 1' > 'LB-2', and the difference between the germplasm resources and 'Yunmi No. 1' reached a significant level. The total sugar and acid content of the germplasm resources were lower than that of 'Yunmi No. 1' in the order of 'LB-2 ' > 'LBBH-1' > 'XSD-1'. The order of sugar to acid ratio was 'XSD-1' > 'LBBH-1' > 'LB-2', with 'XSD-1' being the sweetest, 'LBBH-1 ' the second sweetest and ' LB-2 ' the least sweet in terms of flavor. The germplasm resources all had lower vitamin C content than 'Yunmi No. 1', and the highest soluble solids content was found in 'LB-2', while both 'LBBH-1 ' and 'XSD-1' had lower than the 'Yunmi No. 1'. The overall evaluation index was in the order of 'LB-2' > 'LBBH-1' > 'XSD-1' from high to low. [Conclusion] The order of comprehensive nutritional quality from high to low was 'LB-2' > 'LBBH-1' > 'XSD-1', and the three excellent resources of wild kiwifruit had uniform fruit size, neat and beautiful fruit shape, good flavor, fine texture, and rich juice, which had great development and utilization value.

【Objective】The present paper aimed to understand the effects of altitude and sowing date on the synthesis and accumulation of quinoaquality indexes. 【Method】 Longli 1, a quinoa cultivar, was used as material sowed in the urban area(916 meters above sea level) and Hexin Farm(1800 meters above sea level) of Mangshi, Yunnan province on June 10, September 10, and November 10, 2017, respectively. The main quality properties were determined after harvest.【Result】 In low altitude areas, the high temperature caused the decreasing of the contents of flavonoids, soluble protein and vitamin E, which indicated that these components were not conducive to synthesis and accumulation under high temperature condition, and the increasing of the contents of total amino acids, ascorbic acid, amyloseand mineral element iron, which indicated that maybe a certain range of high temperature was conducive to their biosynthesis and accumulated more; while soluble sugar, amylopectin, mineral elements magnesium, zinc and calcium had little change, indicating the biosynthesis and accumulation of these five indicators were not sensitive to temperature. In high altitude areas, the biosynthesis and accumulation of most indicators were not affected by sowing date.【Conclusion】High altitude areas are most suitable for quinoa growth, but low altitude and high temperature environment are not conducive to growth and development of quinoa. This research provides an important theoretical basis for the selection of suitable sowing date and planting altitude to improve the nutritional quality of quinoa. [ABSTRACT FROM AUTHOR]

[Objective] The purpose of this paper is to improve the yield and quality of Chinese bayberry and promote the development of green-efficient bayberry industry. [Method] Taking Biqi bayberry as test materials, the application of humic acid soluble fertilizer(HASF)was studied for higher yield and better quality fruit, while two field experiments were conducted in Fumin County and Panlong District, Yunnan Province. [Result] The results showed that the yield and fruit quality were improved by spraying HASF with 800-1000 times concentration at pre-flowering, young fruit and fruit enlarged stage, based on conventional fertilization. The average single fruit weight, yield and net income of bayberry of spraying HASF were significantly higher than those of spraying water(CK), with up to 27. 86 %-31. 54 %, 13. 0 %-13. 4 % and 13. 8 %-14. 2 %, respectively, and the contents of soluble solids and vitamin C(Vc) increased by 18. 4 %-19. 54 %and 18. 56 %-24. 9 %, respectively. However, compared with conventional fertilization, spraying water had no significant effect on fruit yield and quality. [Conclusion] The yield, quality and economic benefit of bayberry could be improved significantly by applying HASF. [ABSTRACT FROM AUTHOR]
