摘要
对朋娜、纽荷尔、清家、丰脐果实纵横径定期田间测定 ,研究其生长发育规律及与气温、相对湿度、降雨量、日照的相关性。结果表明 :4个脐橙品种 (系 )果实纵横径在整个生长过程中均出现 3次生长高峰 ,呈单“S”形曲线增长 ,纽荷尔、丰脐出现高峰期比朋娜、清家推迟 5～ 10 d。 7月是果实生长的最大效能期。 4～ 10月果实净生长量与气温、相对湿度、降雨量的变化呈正相关 ,与气温、相对湿度达显著相关性 (P<0 .0 5)或极显著相关性 (P<0 .0 1) ,与降雨量未达显著相关性 (P>0 .0 5) ,说明脐橙园在不受干旱影响的情况下 ,气温、相对湿度是影响果实大小的主要因素。 4品系中 ,纽荷尔最优 ,表现果大 ,皮光滑 ,单果均重 2 2 2 .5g,10月 2 2日分析 ,全糖为 8.57% ,含酸量为1.0 3% ,Vc为 6 3.30 mg/ 10 0 ml,可溶性固形物为 12 %
Lengthwise diameter and breadthways diameter of Skagss Bonanza, Newhall, Seike and Fengqi were measured in the field, the correlation between the growth regulation and the temperature, relative humidity, rainfall and sunshine were studied. The results are as follow:there are three peak points in the whole growth stage, it presents “S” curve. The peak points of Newhall, Fengqi are 5～10 days later than those of Skagss Bonanza, Seike. July is the maximum effective stage of fruit growth. The net fruit growth shows positive correlation with temperature, relative humidity, rainfall. The correlation with temperature and relative humidity is significant (P<0.05) or very significant (P<0.01); the correlation with rainfall is significant (P<0.05), which shows that temperature and relative humidity are main factors affecting the fruit size when the orange garden isn't affected by the drought. Newhall is the best one of the four varieties, the friut is bigger, the peel is smooth (average fruit is 222.5g). The contents of fructose, fruit acid, Vc and total soluble solid (Tss) are 8.57%, 1.03%, 63.30mg/100ml and 12% analysed on Oct.22 respectively.
