Effect
Increased cold stress tolerance
Pepton 85/16 treated Strawberry transplants, cv. Diamante, grown in a tunnel with 5 nights at -6°C just after transplanting had after 60 days on average 57.6 % more dry weight of new roots/total roots, 92.2 % more flowering, a 7.8 % higher survival rate and 57.9 % more accumulated fruit weight compared to the untreated control plants. The highest dose had significant effects on the dry weight of new roots, flowering and fruit weight. The lowest dose only had significant results on flowering and fruit weight.
