Comparison of Growth and Yield Performance of Several Water Chestnut Species Collected from Southwestern Japan and Middle China     

《Plant Production Science》2013,16(4):273-278

Summary

Vegetative growth characters and yield components of water chestnuts distributed in Japan and China were investigated for 12 local lines of 6 species ; i.e., 5 small and 2 medium fruit lines from Japan, and 5 large fruit lines from China. The materials were transplanted and grown in a flooded field usually used for rice cultivation in Saga City in 1995. The lines from China had higher rates of foliage formation, developed emersed leaves earlier and maintained them longer compared with the Japanese lines. The small fruit lines of Japan had the shortest growing period, although the number of rosettes was larger. The fruit yield of the small, medium and large fruit lines, was 250 to 400 g m^?2, about 600 g m^?2 and 600 to 1,000 g m^?2, respectively. The fresh weight of well-ripened fruit was 1 to 5 g for the small fruit lines, 5 to 10 g for the medium fruit lines and more than 10 g for the large fruit lines. The number of fruits per m2 increased as the fruit size of the lines decreased. However, the productivity of the water chestnut was higher in the large fruit lines than in the small or medium fruit lines.  相似文献   

Variation in Growth and Yield Performance of Seventeen Water Chestnut Accessions (Trapa spp.) Collected from Asia and Europe     

《Plant Production Science》2013,16(3):372-379

Abstract

Water chestnut is an aquatic annual herb, and its fresh, edible fruit is a valuable crop. The huge variation in growth and yield of water chestnuts has not been well documented. In this study, the yield performance of 17 water chestnut lines, eight from China (Trapa acornis L., T. bicornis L., T. bispinosa Roxb, T. quadrispinosa Roxb), one from France (T. natans L.), one from India (T. bispinosa Roxb.), three from Italy (T. natans L.), three from Japanese (T. incisa L., T. japonica Flerov, T. natans.L. var. rubeola Makino), and one from Korean (T. japonica Flerov.) were cultivated in Saga City, Japan during the summer, 2005, and the morphological characters of their fruit were analyzed. European lines were early flowering, but had a lower yield due to poor canopy density and lower rosette density. All the Asian lines had a higher rosette density. In spite of the smaller number of fruits per rosette, the Chinese lines had a higher yield than the other lines because the fruit was larger. The yield performance of the Indian line was similar to that of the Chinese lines. The Korean and Japanese lines produced a large number of small fruits per unit land area. Apart from the variation in fruit size, a huge variation in shape including the height, width and the spines were observed. Path analysis revealed that productive rosette number m-² and the single fresh fruit weight are two direct yield determinants while number of fruits per rosette has indirect negative influence on yield via productive rosette number and single fruit weight.  相似文献

中国部分板栗品种的SSR标记   总被引：5，自引：0，他引：5  

艾呈样  余贤美  张力思  刘庆忠 《农业生物技术学报》2007,15(2):283-289

从板栗(Castanea mollissima)燕红中分离到25个SSR标记。为了鉴定这些SSR位点,在重复序列的两侧侧翼序列设计引物,并通过化学荧光检测法对6个板栗样品进行检测,共检测到20个多态性位点,每个位点的等位基因数为2~6个。挑选12个位点,通过半自动系统ABI PRISM377对中国北方24个板栗品种进行分析,这12个标记显示了高达75个等位基因的遗传多态性,每个位点的等位基因为4~10个,平均为6.3个,预期的平均杂合性为0.743(介于0.680~0.845),观察值为0.829(介于0.730~0.930)。无效等位基因估算频率显示为3个位点的正向价值,除了一个位点外,这些价值都很低,鉴定几率为7.01×10-11,亲缘关系鉴定几率非常高,为0.999,足够用于花粉流的研究。  相似文献
