Influence of winter wheat seed stimulation by laser (cv. Radika) on the stages of development, duration of vegetation period and harvest index of grain was investigated. For dates of development stages advancing to heading, between cv. Radika and it's laser treatment weren't noticed significant differences. Noticable differences appear in stages of kernel filling and for duration of vegetation period. Treatments by laser were earlier in maturing from standard for 2-6 days depending of treatment and year. The harvest index of grain at laser treatments was significantly higher and depended from the conditions of year, too.
