Study of the post-effect from the electromagnetic treatment on fresh seeds of Bulgarian pepper varieties (Capsicum annuum L.)
Gabriela M. Antonova-Karacheva
Abstract: A study to establish the post-effect of the electromagnetic treatment on the sowing qualities and morphological characters of fresh seeds from Bulgarian pepper variety “Kurtovska Kapia 1” was performed during the period 2016-2017 in the “Maritsa” Vegetable Crops Research Institute – Plovdiv. The research was conducted under controlled laboratory conditions. It was performed a pre-sowing treatment of the seeds in 12 variants with controllable factors: voltage U (kV), duration of impact τ (s) and time of stay of the seeds from the treatment to sowing - days T. The sowing qualities are studied: germination energy - GE (%) and germination - G (%), and morphological characters: root length ℓr (mm), hypocotyl length ℓh (mm) and cotyledon length ℓc (mm). The best positive effect was found in fresh seeds after treatment with a voltage of 6 kV, lenght of exposure of 35 s and time of stay - 8 days.
