赣中北界引种罗汉果的生育表现

罗汉果原产广西北部,早在1981年我省赣南已获引种成功.1986年起,罗汉果引种由赣南推向赣北,经过几年试种,单株挂果比原产地高出5个,品质较原产地更好。干果:一级枝 Vc 含量194.8mg/100g、总糖含量17.91%;二级枝 Vc 含量210.1mg/100g、总糖含量16.95%.Vc含量比原产地高出53%,总糖含量比原产地高出2%～39.8%。赣中北界引种罗汉果的成功是目前我国纬度较北的地区,这充分说明,无论山区、丘陵、平原都存在农业气候相似的区域。因此,在较高纬度地区也存在着可能种植罗汉果的区域。

THE BEARING MANIFESTATIONS OF MOMORDIA GROSVENORI SWINGLE INTRODUCED INTO THE NORTHERNMOST PART OF CENTRAL JIANGXI PROVINCE

Momordica grosvenori Swingle originates in the Yongfu and Linguiregionsin North Guangxi Province.As early as in 1981,it was successfully introdu-ced to South Jiangxi.Since 1986,it has begun to be planted from South Jiang-xi to North Jiangxi.After several years' experimental planting,its bearingmanifestations have reached or even overtaken the same level as in the placeof its origin.The single plant fruits are five more in number than thosegrowing in the place of its origin.The dry fruit from the first-ratebranches contains 194.8mg/100g of Vc and 17.9% of total sugar,which meansthe Vc content is 53% higher than that of the fruit from the place of itsorigin.The Northermost part of central Jiangxi Province is at the mostnorthern latitude in China at present where Momordica grosvenori Swinglehas been introduced successfully,which indicates that no matter the regionsare mountainous,hilly or flat,they may have similar agricultural climat-es,and therefore possible regions for planting Momordica grosvenori Swingleexist at higher latitudes.
