What does this research mean for the field?

The likelihood of fresh sweet cherries acting as a dissemination route for Prunus necrotic ringspot virus (PNRSV) after human consumption is very low, as the seeds fail to germinate under typical post-consumption environmental conditions due to insufficient cold stratification. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Determine whether sweet cherry seeds from exported commercial fruit can germinate under post-consumption conditions in China and serve as a transmission route for Prunus necrotic ringspot virus (PNRSV).

Overview

Experimental simulation shows zero seed germination across six sweet cherry cultivars under post-import conditions, indicating a very low risk of virus dissemination via discarded fruit.

Key Points

Determine whether sweet cherry seeds from exported commercial fruit can germinate under post-consumption conditions in China and serve as a transmission route for Prunus necrotic ringspot virus (PNRSV).
Assessed seeds from the six most widely exported Chilean sweet cherry (Prunus avium) cultivars under simulated commercial cold storage (0 °C) and regional temperature regimes for Chinese importing provinces (Shanxi, Shanghai, and Shandong).
Compared six post-consumption simulation treatments against a control condition consisting of cold stratification at 4 °C for 3 months followed by transfer to a greenhouse.
Zero seed germination (0%) was observed across all six commercial cultivars under the simulated post-consumption and regional temperature regimes.
Control seeds subjected to a 3-month cold stratification period achieved germination rates ranging from 1.7% to 20.3% across cultivars.
The failure of seeds to overcome dormancy under simulated post-consumption conditions indicates a very low phytosanitary risk of PNRSV dissemination via imported cherry pits.
