The achievement of productive goals in plant mass propagation with the efficiency and efficacy demanded from market competence of in vitro plants nowadays has an unstopped increase of workers productivity, mainly the laminar flow hood operators which are the fundamental force for the in vitro production and its fundamental indicators. The organization in the productive processes requires the use of work norms for each task establishing the workers performance during the working time. The calculation of these norms is supported, as common practice, in the implementation of methods and time analysis techniques. The current work is aimed to show the methodological procedures that have been designed to calculate the work norms in the manipulation of the plant material in the culture rooms in the Cuban biofactories, some examples of its application and general recommendations for its application in the current conditions of the in vitro culture commercial laboratories.

Tissue culture techniques have a huge potential to produce high genetic and sanitary quality seeds. A broad program for the micropropagation of several plants species has been developed in Cuba. It is applied in 16 commercial tissue culture labs distributed throughout the country. The production of in vitro plantlets in commercial tissue culture labs demands closely related processes and operations. The application of methods to plan production is one of them. Planning allows defining, in a timely manner, the human and material necessities to fulfil production. The main methods to plan in vitro production in these labs are presented in the current paper. Experience achieved in Cuba and in other countries of the Latin American area were taken into account. The indispensable elements and variables used to plan production, the types of planning to consider, as well as the responsibilities for their design and development are indicated. The detailed programming of the in vitro production in a commercial tissue culture lab is shown by phase and process. This is used as a reference for suitable planning of the productive process in each of the working areas. [ABSTRACT FROM AUTHOR]
