以甜柿早熟品种'伊豆'、'新秋'和'赤柿'为试验材料,研究其生物学特性、柿果产量、品质和商品率等表现.结果表明,'赤柿'成熟期在8月下旬~9月上旬,'伊豆'和'新秋'在9月中下旬;'伊豆'发枝较少,树势较弱,'新秋'树冠矮小,枝条密生,'赤柿'树势较强;'伊豆'定植13年树平均产量36.2 kg/株,果实扁圆形,平均单果重158.7 g,果皮橙红色,肉质细腻,可溶性固形物含量15.5%,商品果率达93.4%,但硬果期只有10~20天;同树龄的'新秋'平均产量9.6 kg/株,单果重198.5 g,部分柿果有皮裂和蒂隙现象,商品率46.9%;'赤柿'是不完全甜柿,柿果种子和褐斑多,定植13年树平均产量48.3 kg/株,商品价值极低,但因雄花量大、开花早和花期长等特性,可以作为授粉树或种质资源利用.

Three early-maturing non-astringent persimmon(Diospyros kaki) cultivars, 'Izu', 'Shinsyu' and 'Akagaki' were tested. The biological characteristics, yield,fruit quality and the commodity fruit rate of three cultivars were studied. The results show that the harvest time of 'Akagaki' occurs from late August to early September,and the harvest time of 'Izu' & 'Shinsyu' occur from mid to late September. The tree vigor of 'Izu' is less, with a low branch density. The canopy of 'Shinsyu' is small, with a high branch density.'Akagaki' is more vigorous. 13 -2013 - old 'Izu' produced total fruit weight 36. 2kg per tree, the fruit is roundish oblate, weighing about 158. 7g, the skin color is reddish-orange, the flesh is fine, soluble solids content is 15. 5, the commodity fruit rate is 93. 4 percent, but the duration of hard fruit is only 10 to 20 days.At the same time the yield of 'Shinsyu' is 9. 6kg per tree, its fruit is weighing about 198. 5g, Some fruits of 'Shinsyu' have skin cracking or calyx - separation, and the the commodity fruit rate is 46. 9% . 'Akagaki' is a pollination variant non - astringent, there are more seeds and brown specks in the flesh. The yield of 'Akagaki' is 48. 3 kg per tree at 13 - 2013 - old, but its fruit has a poor commodity value. The trees of 'Akagaki' produce a large number of male flowers which blossom early and have a long flowering period, so 'Akagaki' can be used as a pollinizer or germplasm resource.
