摘要本试验所用材料采自华南植物园,广东省农科院果树所和云南西双版纳热带植物所。凭证标本保存在南开大学生物系标本室。春季当幼芽萌发时采取幼芽或幼叶用去壁低渗法进行染色体标本制片。按第一届全国植物染色体学术讨论会的规定进行染色体分析。

Abstract：Chromosomes of 20 species of tropical fruit trees in South China were stu died. The results are as follows:1. 2n = 18 = 6m + 10sm + 2st for Hodgsonia macrocarpa Cogn.2. 2n = 30 = 10m(2SAT)+ 10sm + 4st + 6t for Litchi chinensis Sonn.3. 2n = 30 = 16m + 8sm + 4st + 2t for Euphoria longana Lam.4. 2n = 18 = 12m + 6sm for Clausena lansium(Lour.)Skeels5. 2n = 22 for Psidium guajava L.6. 2n = 34 for Eriobotrya japonica Lindl.7. 2n = 33 = 18m + 15sm for Musa paradisiaca L.8. 2n = 50 for Ananas comosus Merr.9. 2n = 56 for Artocarpus heteropkyllus Lam.10,11. 2n = 48 for both Canarium album(Lour.)Raeusch. and C. pimela Koenig12. 2n = 40 = 20m + 18sm(SAT)+2st for Mangifera indica L.13. 2n = 30 for Diospyros discolor Willd.14. 2n = 34 for Cydonia oblonga Mill.15. 2n = 44 for Syzygium jambos(L.)Alston16. 2n = 18 for Carica papaya L.17. 2n = 18 = 18m for Annona squamosa L.18. 2n = 22 = 12m + 10sm for the wild banana in Guangdong(Musa sp.)19. 2n = 22 = 18m(2SAT)+4sm for the wild banana in Xishuangbanna, Yunnan(Musa sp.)20. 2n = 24 = 22m + 2sm for Persea americana Mill.
