Evaluation of Two Field Inoculation Methods for Testing Resistance to Bacterial Fruit Blotch in Watermelon Fruit
Bacterial fruit blotch (BFB) caused by Acidovoraxcitrulli is a major seed-borne disease that affects watermelon (Citrullus lanatus) seedling and fruit production around the world (5,9). A. citrulli can infect all growth stages of the watermelon plant: seeds, seedlings, foliage, flowers, and fruit(5). The scant research on fruit resistance in favor of foliar resistance has three […]

Histological Studies of Colletotrichum orbiculare on the Susceptible and Resistant Cucumber Cultivars
The infection process of Colletotrichum orbiculare on the leaves of susceptible and resistant cucumber cultivars were studied histologically. On both cultivars, conidia began to germinate 8 h after inoculation (hai) and formed appressoria. Then melanised appressoria formed penetration pegs at 10 hai. On the susceptible cultivar, infection vesicles formed within 24 hai and developed thick, […]

Cucumber (Cucumis sativus) Infection Process of Sphaerotheca fuliginea on Host Cucumber and Honhost Wheat Leaves Yanli Chen and Qing Ma CGC 35 & 36:1-3 (2012-2013) Histological Studies of Colletotrichum orbiculare on the Susceptible and Resistant Cucumber Cultivars Tuo Qi, Jing Yao, Chongzhao Hao and Qing Ma CGC 35 & 36:4-6 (2012-2013)
Infection Process of Sphaerotheca fuliginea on Host Cucumber and on host Wheat Leaves
The infection process of Sphaerotheca fuliginea into epidermal cells of host cucumber and nonhost wheat were studied histochemically. The percentages of germinated conidia had no significant difference on cucumber and wheat leaves at the pre-penetration stage. When S. fuliginea overcame the constitutive barriers of wheat leaf, papillae and hypersensitive reaction were induced to prevent the […]
