摘　　要：HB柚是芸香科Rutaceae柑橘属Citrus L.植物,为人工培育的新品种,在江西赣州市已有试验栽培。根据对HB柚的定点、定位观测研究,其生长发育生物学特性有:(1)HB柚叶片在7天内长成,生长速度较快;(2)果实的直径和高生长与果实的重量生长都呈双"S"形曲线,都表现为"快-慢-快-慢"的生长节律特点,但果实重量生长的两个高峰期落后于直径和高生长的两个高峰期,表明果实形态构建在先,内含物质的转化和积累滞后;(3)HB柚的果肉占果重的74%,果皮为果重的26%,可食率较高,HB柚果肉的生长规律与果实重量的生长规律具有一定的吻合性特点,但果皮的生长却出现了负增长现象;(4)HB柚具有芽膨大期稍迟、芽抽枝发梢次数较多、开花数量多、果实成熟期较晚等物候特点。Citrus maxima（Burm.） Merr.＇HB You＇ is a new cultivar that belongs to the genus Citrus of Rutaceae and has been cultivated in Ganzhou of Jiangxi Province,China.Based on the fixed position observation,the biological characteristics of C.maxima are as follows.（1）The leaves of C.maxima grew up to adult leaves（in length and width） within 7 days,their growth velocity were faster then others.（2） Both fruit diameter and height were related to fruit mass,their relative curves were ＂2S＂ curves,which showed rhythm of growth like ＂quick—slow —quick—slow＂.But the two high peaks of fruit mass curves appeared behind corresponding two high peaks of fruit size curves（diameter and height of fruit）,which means that the completion of fruit size construction got earlier and the process that fruit components changed into other elements was later or longer.（3） The mass of single fruit pulp was 74% of the fruit total mass and that of its peel was 26%,this shows that eatable rate of a fruit was higher.Based researches above,the growth regularity between the mass curve of fruit and the curve of pulp mass were more similar.Having been measured the mass of fruit peel,it is found that a negative growth of peel mass appeared on the relative curve,which is valuable to pay attention.（4） Main phenology characteristics of this new cultivar are follows such as bugs expanding later,more new branches and more times of drawing new branches,more flows and date of mature fruit later.
