马来西亚无胶菠萝蜜在海南引种试种表现

对马来西亚无胶菠萝蜜在海南的品种表现性状进行研究，结果表明．8a树龄植株果实为长椭圆形（果形指数为2．11，平均值。下同）．果实横径（25．47cm）、包刺长（0．59cm）、果轴重量（1．47kg）、果轴横径（7．73cm）、果苞数（211．7枚）、种子数（176．3粒）、百粒种重（822．46g）、种子纵径（3．74Cm）、种子横径（1．95ore）等9项指标与对照相当；而单果重（18．02kg）、株产（369．7kg）、果实纵径（53．47cm）、果皮重（2．34kg）、果皮厚（1．17cin）、果轴纵径（46．70cm）、单果苞重（43．69g）等8项指标均极显著或显著地高于对照；包刺密度（180枚／dm2）则显著低于对照；果苞厚（0．57cm）、可食率（51．33％）与本地湿苞种（SS1）相近，而显著大于本地干苞种（SS2）；TSS含量（17．39％）显著低于SS2．但高于SS1。

Introduction and Experimental Planting of Malaysian Latex-free Jackfruit in Hainan

The varietal performance traits of Malaysian latex-free jackfruit in Hainan were studied. The results showed the fi-uits of 8-year-old plants were oblong shaped （fruit shape index=2.11, average, similarly hereinafter） in which there were no significant difference in 9 kinds of indexes including the fruit transverse diameter （25.47 cm）, spike length （0.59 cm）, fruit axis weight （1.47 kg）, fruit-axis transverse diameter （7.73 cm）, number of bulbs （211.7） and seeds （176.3）, 100-seed weight （822.46 g）, seeds longitudinal diameter （3.74 cm） and transverse diameter （1.95 cm） while comparing with the control; but 7 kinds of indexes such as the fruit weight （18.02 kg）, yield per plant （369.7 kg）, fruit longitudinal diameter （53.47 cm）, rind weight （2.34 kg）, rind thickness （1.17 cm）, fruit-axis longitudinal diameter （46.70 cm） and single bulb weight （43.69 g） were significantly （/9〈0.01 or 0.05） higher than control and the spike density （180/dm2） was significantly （/9〈0.05） less; the bulb thickness （0.57 cm）and edible rate （51.33%） were not more than the wet-bulb variety （SS1） but significantly （p〈0.05） more than the local dry-bulb variety （SS2）; the TSS content （17.39%） was just between dry-bulb variety and the wet-bulb variety at p〈0.05 level.
