Other claims from this paper (12)
- Observation 64% of 25 kiwifruit germplasm accessions exhibited resistance to brown spot, including three highly resistant cultivars.
- Observation Most commercial and wild germplasm accessions were moderately resistant or highly susceptible.
- Observation Resistant kiwifruit types had 64.55% lower stomatal density than susceptible ones.
- Observation Resistant kiwifruit types had 60.05% more trichome branching than susceptible ones.
- Observation Resistant kiwifruit types had 52.28% higher epicuticular wax content than susceptible ones.
- Observation The structural traits of resistant types delayed appressorium formation by 12 hours.
- Observation The structural traits of resistant types hindered penetration peg development.
- Observation After infection, resistant plants activated a ROS burst, hypersensitive reaction and extensive lignin deposition.
- Observation In LS, four defense enzyme activities reached 1.12-1.57 times the levels in HY.
- Observation Six defense-related genes were significantly up-regulated within 48 hours post-inoculation.
- Observation Stepwise regression of 22 variables identified five key predictors of resistance.
- Method / resource A model based on the key predictors achieved 94.24% accuracy (R2 = 0.95) in field validation for estimating kiwifruit resistance.
