Fusarium Species Isolated from Mangrove Soil in Kampung Pantai Acheh, Balik Pulau, Pulau Pinang, Malaysia

Abstract

A total of 33 isolates of Fusarium sp. were isolated from soil samples collected from a mangrove forest in an area in Kampung Pantai Acheh, Balik Pulau, Pulau Pinang, Malaysia. The isolates were isolated using soil dilution, direct isolation and debris isolation techniques. The debris isolation technique yielded the most isolates, with a total of 22 Fusarium isolates. Based on identification using morphological characteristics, three Fusarium species were identified: F. solani, F. oxysporum and F. verticillioides. F. solani (91%) was the most common species recovered from the mangrove soil samples, followed by F. oxysporum (6%) and F. verticillioides (3%).

Sebanyak 33 pencilan Fusarium telah dipencilkan daripada sampel tanah di satu kawasan hutan paya bakau di Kampung Pantai Acheh, Balik Pulau, Pulau Pinang. Kesemua pencilan tersebut diperolehi menggunakan kaedah pencairan tanah, pemencilan terus dan pemencilan sisabaki tumbuhan. Kaedah pemencilan sisabaki tumbuhan menghasilkan pencilan Fusarium yang paling banyak iaitu 22 pencilan. Berdasarkan ciriciri morfologi, tiga spesies Fusarium dapat dikenalpasti iaitu F. solani, F. oxysporum dan F. verticillioides. F. solani (91%) merupakan spesies yang paling kerap diperolehi daripada sampel tanah hutan paya bakau diikuti dengan F. oxysporum (6%) and F. verticillioides (3%).
