The present study aimed to assess the diversity of saprobic fungi associated with three decompositional stages of Hevea brasiliensis (Wild. ex Juss.) Mull. Arg. leaves along a chronosequence of plantations. The modified surface disinfection culture method was followed for isolation of saprobic fungi from three different phases (G₁, G₂ and G₃) of decomposing leaves. The result revealed 51 species of fungi isolated from three plantations. There was an increasing trend of number of species along a chronosequence of plantations. Cladosporium sp. was isolated from all the phases of decomposition from all the three plantations. There is an increasing trend in diversity and a decreasing trend in dominance of fungi along a chronosequence of plantations. Overall, higher number of species and maximum diversity was recorded in G₂ (Hʹ = 3.61) among the decompositional phases. The study suggests increase in diversity along a chronosequence of plantations and the similarity index suggests distinct fungal occurrence pattern in the leaf litter along a chronosequence of plantations.

本研究旨在评估与巴西橡胶树的三个分解阶段相关的腐生真菌的多样性。精氨酸 沿种植园的时间顺序离开。遵循改良的表面消毒培养方法，从腐烂叶片的三个不同阶段（G ₁，G ₂和G ₃）分离腐生真菌。结果揭示了从三个人工林中分离出的51种真菌。人工林的时间序列中物种数量呈增加趋势。枝孢菌sp。从所有三个人工林的所有分解阶段中分离得到。种植园的时间序列上，真菌的多样性呈上升趋势，而优势度呈下降趋势。总体而言，物种和最大分集的更高数目被记录在G中₂（H'  = 3.61）的decompositional相之间。该研究表明，随着人工林的时间序列多样性增加，相似性指数表明随着人工林的时间序列，落叶中的真菌出现明显的不同模式。
