用发根农杆菌 232 处理的裸根杏仁树在 90 天后比用高压灭菌或过滤灭菌的细菌悬浮液或仅用培养基处理的裸根杏仁树具有更大的根数和根质量。用A. rhizogenes 232处理还导致处理后第一个生长季节期间叶数、茎直径和芽伸长显着增加。该细菌可以从根际和处理过的根周围的大块土壤中回收，但不能从未接种的对照根中回收。因此，杏仁对发根农杆菌的反应并不是病理性的，尽管这种细菌被归类为病原体。
Bare root stock almond trees treated with Agrobacterium rhizogenes 232 had a larger root number and root mass after 90 d than those treated with autoclaved or filter-sterilized bacterial suspensions, or with medium alone. Treatment with A. rhizogenes 232 also led to significant increases in leaf number, stem diameter and shoot elongation during the first growing season after treatment. The bacterium was recoverable from both the rhizosphere and the bulk soil around the treated roots, but never from uninoculated control roots. Thus, the reaction of almond to A. rhizogenes was not a pathological one even though this bacterium is classified as a pathogen.
