“…wasabiae (possibly members of the new species P . parmentieri ; Khayi et al, 2016) have been reported in Iran (Baghaee‐Ravari et al, 2011; Baghaee‐Ravari & Gerayeli, 2015; Dahaghin & Shams‐Bakhsh, 2014; Dana et al, 2015; Rafiei et al, 2015; Rezaee Danesh et al, 2021; Rezaei & Taghavi, 2010). These studies were mostly based on phenotypic tests, specific primers, analysis of whole‐cell protein electrophoresis patterns, rep‐PCR and in some cases 16S rRNA sequencing.…”

Soft rot‐inducing bacterial pathogens are considered among the main biotic constraints on vegetables and annual crops. Most of the bacterial soft rot pathogens are members of Pectobacterium spp. and Dickeya, with the former genus encompassing a continuously increasing number of species varying in geographic distribution and host of isolation. In Iran, Pectobacterium species have rarely been investigated using high‐throughput nucleotide sequence‐based techniques, leaving the genetic diversity of these pathogens mostly undetermined. During 2021, vegetables and annual crops with symptoms of soft rot and maceration were collected from Fars, Hamedan, Isfahan, Khuzestan and Kohgiluyeh‐Boyer‐Ahmad provinces of Iran. Forty‐four pectinolytic bacterial strains were isolated from symptomatic tissues of bell pepper, cabbage, carrot, lettuce, potato and zucchini. The bacterial strains were subjected to pathogenicity and host range assays, specific PCR tests and phylogenetic analysis of three housekeeping genes (dnaX, gapA and leuS). All strains were pathogenic on their host of isolation. Among the 44 pectinolytic strains, 26 strains were identified as members of Pectobacterium based on PCR using the primer pair Y1/Y2. Multilocus sequence analysis confirmed the latter bacterial strains belonging to the genus Pectobacterium and revealed that the strains scattered into four species: P. brasiliense (five strains), P. carotovorum (eight strains), P. polaris (five strains) and P. versatile (eight strains). P. polaris and P. versatile have not previously been reported in the country. Host range assays showed that P. brasiliense and P. carotovorum have a broader host range than the other two species.

The intensification processes characteristic in industrial fruit growing is given, their aims are determined. The main technological shifts of the technological structure formed in the domestic fruit growing are presented. Based on the analysis of the technological structure development, the predicted technological shifts for the near future, the characteristic features of promising technologies in the fruit growing, their criteria and signs are presented. The factors-indicators of fruit growing intensification are systematically presented. A retrospective of the industrial fruit growing intensification based on the weak-growing rootstocks breeding and introduction and differentiated technologies formed with their participation is reflected. The main directions of intensification that increase the agrocenosis biopotential are graphically presented. The analysis of chemical and technogenic factors negative impact on agroecocenoses leading to bioresource deformations in the biocenosis, soil and soil microbiota, microbio-, acaro- and entomosystems is carried out. The necessity of restoring and developing the reproductive capabilities of agroecosystems, mainly by biological methods, is proved, which include: the development of rhizosphere microorganism populations in the soil biota, the range expansion of the applied bioproducts created on the effective strain basis of beneficial microorganisms, the widespread application of various forms and methods to increase plant immunity, including elicitor-type preparations.

“…The nursery, as main point, is a set of elements organized by specific agro-technological processes aimed at the production of planting material and fruit saplings of higher quality categories: the selection of initial breeding material, the identification of varietal identity; testing plants phytosanitary state, improvement of initial material, cultivation of plants of origin category; creation and cultivation of the uterine stick garden, uterine seed garden, plantations for growing the vegetative propagated rootstocks, schools of seedlings, plots (fields) for growing; plant protection against diseases and vermin's; varietal testing of rootstocks and saplings of fruit crops in the nursery, certification of planting material and saplings [6,7].…”

The necessity of reformatting the structural organization of processes, which determines the priority of using the ways, forms and methods of the sixth technological structure, in particular, biotechnologies is actualized. The main definitions are given: nursery, biologization, greening, resource saving, promising technology. The analysis of the efficiency of sapling fruit production, the structural organization of specific processes for the production of planting material and sapling is presented. The main elements of the agrocenosis, which are most susceptible to chemical and technogenic effects, have been determined. The analysis of soil fertility and the state of soil biota is carried out, the problem of microbiological processes branch in all agrocenosis elements is actualized. It was found that the increased chemical load on the agrocenosis of the fruit nursery led to the destruction of microflora useful species. The nature of plant organs infection has changed, and negative changes have occurred in the plants immune status. The priority role of biologization in ensuring the stability of the fruit nursery agrocenosis has been substantiated.
