A new and generalized data on diversity and ecological features of species distribution of Closterium in Tajikistan water bodies are given. Recently 25 species, 5 interspecies and 6 forms of this genera were found in Tajikistan water bodies. Among them Сlosterium leibleinii Kütz. ex Ralfs, C.pritchardianum Arch. are wide distributed in different types of Tajikistan water bodies, but Closterium acutum (Lyngb.) Brеb., C.libellula Focke ex Ralfs and С.lineatum Ehr. ex Ralfs - fixed as rare species. |

This article deals with the data on the species composition and distribution of 36 species of blood-sucking biting midges belonging to 7 genera, their distribution at collection points on the northern and southern outskirts of the Hissor Valley, and their correlation in these points by genera. Thus, the Gissar valley and the foothills of the southern slope of the Gissar range are likely to be rich in species relative to other areas of southern Tajikistan. |

The article presents the results of a study on the study of leaf area in varieties and lines of common wheat (T.aestivum L.), depending on the growing conditions. It was found that the maximum leaf area of wheat varieties and lines under all growing conditions falls on the heading phase. It was revealed that the Orien variety under all growing conditions has the best indicators of leaf area (from 70.8 to 89.9 cm/plant). |

of Tajikistan |
The yield structure mapping lines of wheat from world collection of N.I.Vavilov VIR in different ecological regions of the Republic of Tajikistan are studied. The obtained data show that, depending on the climatic zones of Tajikistan, located at different heights above sea level, the height of plants, as well as the parameters of the crop structure - "ear length", "ear weight", "number of spikelets in an ear", "grains per ear", "weight of grains per ear" and "weight of 1000 grains" change. |

in vitro and ex vitro of solanum tuberosum L. regenerant plants |
The content of photosynthetic pigments on Solanum tuberosum L. plant-regenerants was studied under in vitro and ex vitrо conditions. It was found that in vitro and ex vitro the content of chlorophylls (a + b) and their ratio, as well as the content of carotenoids, differ significantly, which has a certain effect on the assembly of the light harvesting complex (LSC) of the photosystem and is one of the indicators of plant adaptation to stress factors. It was shown that, under conditions of water deficit, the proportion of Chl a in the total pigment content decreases to a greater extent than Chl b, regardless of the plant genotype. |
