Method of Silicon Application Affects Quality of Strawberry Daughter Plants during Cutting Propagation in Hydroponic Substrate System

Summary

The beneficial effects that silicon (Si) has on plant growth as well as resistance to biotic and abiotic stresses have been well documented for many crops in recent years. However, few studies focus on the effects of Si on plant growth during the propagation stage of strawberry (Fragaria × ananassa, Duchesne). This study was conducted to investigate the optimal method for Si application during the cutting propagation of strawberry in soilless cultivation. Strawberry mother plants were supplied with Si through foliar spray, runner spray, or root drench before the cutting propagation, then half of the daughter plants in each treatment received continued Si supply through foliar spray or through root drench after the cutting propagation. The results showed that the plant height, petiole lengt
