Influence of container cell capacity on the development of pepper (Capsicum annuum L.) seedlings

Abstract

Containers are frequently used in the production of seedlings because they are practical and easy to maintain. There are different types of containers. Each type has its own advantages and disadvantages, like: purchasing price, duration, availability, conditions of keeping, transport, etc. Their size and shape can be very different. The size of the containers (cells) is crucial for the production of the seedlings. It has to be in correlation with the type of seedlings grown and with the duration of the production. Competent and experienced people can easily determine the right container size for a certain production of seedlings. Research was done in greenhouses. Plastic containers were used. The cell capacity varied from 7.3 to 80 cm3. The parameters crucial for the development of the seedlings as well as their qualities (the height of the plant, number of leaves, mass of the plant) were analyzed. Pepper seedlings were forming well only in 80 cm3 cells, thus they need to be grown in 80 cm3 cells or somewhat bigger cells. In cells which capacity varies from 7.3 to 33.5 cm3 seedlings used for stinging can be grown.

Kontejneri se dosta koriste u proizvodnji rasada, jer su praktični i lako se održavaju. Postoje različiti tipovi kontejnera. Svaki od njih pokazuje određene prednosti i nedostatke, kao što su: nabavna cena, trajnost, dostupnost, pogodnost čuvanja, transport i drugo. Veličina i oblik izrazito im variraju. Veličina kontejnera (ćelija) ima odlučujući značaj za proizvodnju rasada. Ona mora biti u korelaciji sa vrstom gajenog rasada i trajanjem proizvodnje. Ogledi su izvedeni u staklenicima. Korišćeni su plastični kontejneri. Zapremina ćelija varirala je u rasponu od 7,3 do 80 cm³. Proučeni su parametri od kojih najviše zavisi razvijenost rasada, kao i njegov kvalitet (visina biljke, broj listova, masa biljke). Rasad paprike dobro se formirao samo u ćelijama od 80 cm³, pa ga treba gajiti u ćelijama te ili nešto veće zapremine. U ćelijama čija zapremina varira od 7,3 do 33,5 cm3 mogu se gajiti sejanci koji služe za pikiranje.
