Fusarium wilt is a serious disease that causes damping-off, serious wilt symptoms, or death in melon. The aim of this study was to evaluate the resistance of melon germplasm to Fusarium wilt and select promising disease-resistant accessions for further applications. Resistance to Fusarium wilt was examined in 216 melon germplasms by the root-dipping inoculation method with Fusarium oxysporum f. sp. melonis fungal isolate KACC43206 (race 2). Inoculated seedlings were incubated for four weeks and assessed for disease symptoms using indices ranging from index 1 (no symptoms) to 5 (plant wither). A total of 34 accessions showed a disease index < 2.0. Disease indices of 10 accessions were 1.0 four weeks after inoculation. The resistant accessions of melon are expected to help in breeding commercial varieties with Fusarium wilt resistance.

We investigated the effect of pre and post-cryopreservation treatment on the dehisced Ginseng (Panax ginseng C.A. Meyer) seeds germination rate. All seeds covered with endocarp and 96.3% of them were opened, initial moisture content (IMC) and germination rate were 55.9% and 84.0%, respectively. According to the pre and post-cryopreservation methods, highest seeds germination rate (GR) was observed in non-precooled seeds which recovered at 40°C, in which MC was 8-12% and desiccated at 15°C. However, by prolonged drying the seeds GR comparatively decreased under MC of below 2.2%, reaching below rate 4% regardless of pre and post- cryo treatments, whereas the seeds dried at 25°C airflow cabinet saved significantly high rate. The effects of desiccation and of cryopreservation on the survival and developmental pattern of roots and stems showed that the earliest appearance of the root in control seeds was detected after 10 days of bedding in GA medium, and the stem started to develop later on the third week of germination test. And, on the 30th day of the investigation stem growth rate significantly increased and showed equivalent data with root rate. Almost the same pattern showed the seeds after cryopreservation, but it significantly delayed in the development compared to control, where term of the investigation continued till 40 day than control 30 day. Additionally, non-precooling seeds in both desiccation and recovery methods were showed high root and stem growth compared to precooled treatments.
