One of the most important problems in horticultural seed science and technology nowadays is looking for new methods to improve seed quality. Especially interesting are the ones, in which compounds of natural origin are used. One of such groups is ethereal oils from plants. The commercial seed samples of lettuce (Lactuca sativa L. ‘Dumka’) were soaked in 9 different treatments of 5% alcoholic solution of camphor tree (Cinnamomum camphora L.) ethereal oil and 9 different treatments of 5% alcoholic solution of patchouli plant (Pogostemon cablin Benth.) ethereal oil. Then the seeds were routinely tested for seed germination, the length of the received seedlings was also measured and the seeds health status was evaluated. The tested ethereal oils had no effect on the germination of lettuce seeds. However, soaking the seeds in the ethereal oils solutions did decrease the percentage of dead seeds in the tested samples. Soaking of the seeds in the ethereal oils solutions also increased the percentage of healthy ungerminated seeds. Treating the seeds with the concentrations of the ethereal oils solutions, although had no effect on their germination, still shortened the length of seedlings. Moreover, the used ethereal oils lowered the amount of identified Alternaria alternata and Cladosporium sphaerospermum fungi on the seeds.

Jednym z najważniejszych problemów nasiennictwa ogrodniczego dziś jest poszukiwanie nowych metod poprawy jakości nasion. Szczególnie interesujące są te z nich, w których wykorzystuje się substancje naturalne. Jedną z takich grup są olejki eteryczne z roślin. Nasiona handlowe sałaty (Lactuca sativa L.) odmiany Dumka potraktowano na 9 różnych sposobów 5% alkoholowym roztworem olejku eterycznego z drzewa kamforowego (Cinnamomum camphora L.) i na 9 różnych sposobów 5% alkoholowym roztworem olejku eterycznego z paczuli (Pogostemon cablin Benth.). Następnie nasiona poddano rutynowej ocenie kiełkowania, zmierzono długość otrzymanych siewek i oceniono zdrowotność nasion. Badane olejki eteryczne nie wpłynęły na kiełkowanie nasion sałaty, natomiast zmniejszyły odsetek martwych nasion w badanych próbach. Moczenie nasion w badanych roztworach olejków zwiększyło także odsetek nasion zdrowych niekiełkujących. Traktowanie nasion roztworami olejków eterycznych o wyższych stężeniach, choć nie wpłynęło na ich kiełkowanie, to jednak skróciło długość otrzymanych z nich siewek. Ponadto stosowane olejki eteryczne obniżyły ilość oznaczonych na nasionach grzybów: Alternaria alternata i Cladosporium sphaerospermum.
