摘要
‘青丽’是从青皮石榴无性系中选育出的抗旱、抗裂果石榴新品种。果实近球形,果皮底色黄绿、表面着鲜嫩红色,平均单果质量410 g。籽粒红色,平均百粒质量45 g,可溶性固形物含量17.1%,总酸含量2.70 g·kg-1,鲜果出汁率47.5%,平均裂果率低于6.2%。果实发育期125 d左右,在山东枣庄地区10月上、中旬成熟。抗旱、抗裂性较强,适于干旱瘠薄山坡地栽培,丰产、稳产。
＇ Qingli＇ selected from Yicheng green husk pomegranate, is a new drought-resistant and crack- resistant pomegranate cuhivar. In 2004, in order to breeding the pomegranate cultivars with crack resistance, drought resistance and storage resistance, our research group firstly carryed out the census pomegranate germplasm resources work in Zaozhuang, Jining, Taian, Yantai, Linyi and other places. We selected pomegranate superior individual, then weeded out the inferior individuals by cutting, grafting, and vari- eties comparison experiments, then checked out superior strains. After regional adaptability testing at three sites （Wangfushan village, Liuyuan town, Yicheng district; Zhangzhuang village, Shagou town, Xuecheng district; Xi village, Xiwangzhuang town, Shizhong district） over seven years from 2006 to 2012, it was finally selected in 2013. ＇ Qingli＇ is a dwarfing tree, attaining a height of 2.6-4.2 m. The tree is vigorous with semicircular crown and upright gesture. The trunk is grey-brown in color, glabrous. Perennial branches are dark gray. Annual branches are pale, upright, have much hard stem thorn. Leaves opposite or fascicled, long elliptic, entire, base cuneate, lobes acuminate, leaves are leathery and smooth. Young leaves are yellow green, mature leaves are dark green, veins are yellowish green, 7.5 cm long, 1.9 cm wide, petiole pale violet red, 6 mm long. Flower is red, large amount, single-lobe and has 6 pieces petals, 1 pieces pistil, about 110 pieces stamens. Calyx is tubular or bell-shaped, hypanthium medium, sepals erect. It flowers three times one year, and proportion of tubular flowers is about 28%. The fruit is nearly spherical, bottom colour is yellow-green, fresh surface is red, average fruit mass is 410 g, Grain red, average 100-grain mass 45 g, soluble solid content 17.1%, total acid content 2.70 g. kg-1, fresh fruit juice yield 47.5%. The fruit development period was about 125 d, and it matures in early and middle October in Zaozhuang. The trees are drought-resistant, the average dehiscent fruit rate is lower than 6.2%. Suitable cultivation area is dry barren slope cultivation, this variety can bear fruits next year after planted, has high and stable yield, comprehensive quality excellent. The best planting area is in mountain and hill slope around 120 m above sea level, other slope is sub-suitable planting area. Orchard establishment in plains and beaches percent, freezing injury＂ should be considered, antifreezing measures should be taken.
