Response of carnation varieties to pinching and boron

An experiment was carried out to assess the influence of different pinching methods and levels of boron spray on carnation varieties. The varieties under evaluation were Baltico (V1), Domingo (V2), Penelope (V3) and Kiro (V4); four levels of pinching were no pinch (P0), single pinch (P1), single and half pinch (P2) and double pinch (P3). Three levels of boron were control (B0), 0.05% (B1) and 0.1% (B2). The experimental results revealed that all the recorded parameters were significantly influenced by variety, pinching and boron.
