Research in Istrița over time has had a broad topic area that has evolved into the needs of fruit growing in its various stages of development.

In the first years after its establishment, a rich collection of varieties of almost all species of fruit trees and shrubs was made. The varieties of the collections, the most valuable ones at that time, were recommended in the first rationing and micororioning of the varieties. At the same time, there were also concerns about different forms of leadership, very prevalent in Europe at the time.

In the nursery sector, parallel to the production activity, the researchers who worked here also had concerns about the creation and multiplication of the most valuable varieties of rootstocks, as well as the establishment of the most suitable pepper farming agrotechnics.

Specialists who worked in Istrița in this period have gained valuable research results, which can be structured in two major directions:

  • creation of new varieties of trees and high quality fruit trees with selected qualities, resistant to diseases and pests, adapted to climatic and soil conditions in the area of influence
  • the comparative study of the new varieties of trees with the foreign varieties for the purpose of choosing, and introducing into the culture of the most valuable

In 1958 there were 154 varieties in Istrița, of almost all species of fruit trees, the predominant species being plum with over 50 varieties.

After 1964, the orchards existing here were used exclusively for production purposes. Treated, varieties after varieties have been extinct, being replaced by orchards organized according to the principles of increased productivity in ha., The last collection of apple varieties being grubbed out during the period 1977-1978.

The Pepiniera Istrița continued its production, ensuring the planting material for Buzău County and the neighboring areas.
The research activity in Istrița was resumed in 1977, with the establishment of the Pomace Research Station in Buzău , and focused on the issue of tree propagation.

With permanent attention to the characteristics of the fruit-growing area of the Bend Subcarpathian, the research was subordinated to the following themes:

  1. Improvement of fruit tree propagation technologies. Within this theme, the research activity responded to the needs of the production sector:
    • setting up and structuring of the parent plantation of grafting;
    • preserving the biological value and health of the propagating material;
    • improving the technologies for setting up, maintenance and exploitation of seedlings plantations;
    • testing the behavior of tree species in the school of new, homologated varieties and elites with the prospect of approval as varieties, on the variety of rootstocks admitted to propagation;
    • reducing the production time of grafted trees by producing rootstock saplings in pots;
    • the use of foliar fertilizers in the nursery;
    • reducing the loss of grafted trees by failing to graft or freezing grafted shoots over winter.
  2. Study of the adaptability to the edaphocllimatic conditions of the valuable rootstocks of the Romanian and world assortment for their correct zoning.
    The studies have made it possible to determine the behavior of the most valuable rootstocks in the current range, in the area of the Curb Subcarpathians, the influence zone of the Buzău Pomicole Resort
  3. Collecting, preserving and studying germ plasm for rootstocks improvement.

Considering the richness of spontaneous flora and cultivated in local biotypes and varieties that are interested in the process of improving the plum rootstocks, the concerns have been focused on this species.

It has thus been concluded that the ecological area of the Curved Sub-Carpathians, through the natural germplasm fund for the Prunus genus, is a valuable genetic material and an important source of genes for the works of plum rootstock melioration.
Based on HG 2155/2004, the Istriţa farm was taken over from 01.01.2005 by the University of Agronomic Sciences and Veterinary Medicine Bucharest, becoming its subsidiary.

The research activity was carried out both on the basis of contracts with different sources of financing and through own research without direct financing.

Among the research projects carried out during this period can be mentioned the researches regarding the implementation of modern techniques in the nursery practice, in order to increase the efficiency and the competitiveness in the production and exploitation of the fruit and dendrological planting material:

  • the implementation of grafting and dendrological plant production techniques as an alternative to the modernization of the hunting practice;
  • achieving the experimental growth platform model for obtaining container seedlings;
  • the improvement of the propagation technology by shunting in the fruit and dendrological tree species, by guiding the exogenous factors as a stage of the technology for producing the planting material to the containers;
  • improving the propagation technology by grafting the fruit species, to reduce the production time of the propagating material;
  • microinducing in vitro of arbustive and dendrological fruit plants to obtain total free virus progeny (LTV).

The research activity is carried out by integrating the team from Istriţa into the research projects of the Department of Fruit Growing, respectively of the Research Center for Integrated Fruit Growing.
