(a) Black rot symptoms caused by Xcc strains on inoculated leaves of host cabbage plant. After 14 days inoculation, the photographs were taken. (b) Mean lesion lengths caused by different Xcc strains. Values shown are the average ± standard deviation from three repeats, each with six leaves. Significance was determined using the Student t test (* indicates significance at p < 0.05)Back to article page
