【摘要】 以8个国内外引进的优良芒果品种为材料,对照本地三年芒,系统研究了其在元谋的物候期、产量等性状表现,评价其在干热河谷(元谋)的适应性。结果表明:R2E2和热农1号生长势强,热农1号单株产量最高,为56.56 kg;Mallika和热农2号树势中等,产量中等;Valencia Pride树势强,果实耐贮藏,是长途运输优选的品种;Keitt树势低矮,晚熟,单株产量21.94kg;Zillate和Banganpalli树势强,但是挂果期受虫害严重。综合评价,以R2E2和热农1号的生物学相关性状优;热农2号、Mallika和Valencia Pride的生物学特性表现良好;其余品种的生物学特性表现一般。更多还原

【Abstract】 The phenological period, yield and other characters of eight mango varieties introduced from home and abroad were studied systematically, and their adaptability in the dry-hot valley of Yuanmou was evaluated. The results showed that R2E2 and Renong 1 had strong growth potential, and the highest yield per plant was 56.56 kg obtained by Renong 1; Mallika and Renong 2 had medium tree potential and moderate yield; Valencia Pride was of vigorous tree potential, and endurable to fruit storage and long-distance transportation, thus it was a preferred variety; Keitt was low in tree potential, and late maturing with a yield of 21.94 kg per plant. Zillate and Banganpalli were strong in tree potential but suffered a serious damage from insect pests during the fruiting season. According to the comprehensive evaluation,R2 E2 and Renong 1 were of the best biological characters, Renong 2, Mallika and Valencia Pride performed well, the others were ordinary.更多还原
