The research was aimed at studying the morphological changes of tolerant and susceptible soybean genotypes exposed to drought stress and inoculated with mycorrhiza. In this study Sindoro, Lokon, and MLG 3474 genotypes infected with Glomus etunicatum were tested at three levels of drought stress, e.g. : 80%, 60%, and 40% of field capacity (FC). The experiment was conducted in green house at the experimental field of Meteorological Station, Sampali, Medan, from September 2001 to January 2002. The results showed that drought stress at 40% FC suppressed leaf area and stem diameter. The positive role of VAM in supporting plant to overcome the drought stress inpacts was more significant in the less tolerant than that of more tolerant genotypes.

Pada penelitian ini diuji genotipe Sindoro, Lokon, MLG 3474 yang bersimbiosis dengan Glomus etunicatum pad a tiga tingkat cekaman kekeringan : 80% KL, 60% KL dan 40% KL. Percobaan dilaksanakan di rumah plastik kebun percobaan Stasiun Klimatologi Sampali, Medan, dari bulan September 2001 sampai dengan bulan Januari 2002. Hasil penelitian menunjukkan cekaman kekeringan 40% KL menyebabkan menyempitnya luas daun dan diameter batang mengecil. Peranan positif MVA dalam membantu mengatasi cekaman kekeringan lebih besar pada genotipe yang peka daripada yang toleran
