INFLUENCE OF INTENSIVE PROPAGATION TECHNOLOGY OF POMEGRANATE SEEDLINGS ON QUALITY INDICATORS

Mon, 03 Feb 2025 00:00:00 +0000

The pomegranate industry is considered highly profitable. It is necessary to develop the ancient traditions of pomegranate cultivation on the basis of scientific achievements, select and propagate varieties suitable for the soil and climatic conditions of each region, and conduct scientific research on obtaining high yields from them in each household. Pomegranate (P. granatum) is one of the fruit plants cultivated in our country since ancient times. The yield and quality of pomegranates often depend on the quality of the seedlings planted. High-quality seedlings are grown in special nurseries.

This article presents data on the initial growth parameters of finefibre cotton varieties under soil salinity conditions. Laboratory experiments were conducted to examine the effects of soil salinity on the fine-fibre cotton varieties Surkhan-16, Surkhan-18, Termez-202, Termez208, and SP-1607. The experiments were carried out in laboratory conditions using containers with a capacity of 2 kg of soil. The first group of containers contained non-saline soil, while the second group had soil treated with a 0.3% sodium chloride (NaCl) solution to simulate salinity conditions. During the experiments, key growth indicators such as root growth rate, root volume, stem length, leaf surface expansion, fresh weight of the seedlings, and total water content in the plant tissues were analyzed. The results revealed that these parameters varied significantly among the studied varieties, depending on their salinity tolerance and biological characteristics. The findings highlight the importance of selecting appropriate fine-fibre cotton varieties for cultivation in saline soils, as their adaptability and resistance levels play a crucial role in ensuring stable growth and development under salinity stress

FORMATION OF FIBER’S LENGTH AND FIBER’S YIELD OF COTTON PLANT

The article analyzes the fiber yield and fiber quality, which have a negative correlation coefficient, using different methods of selection in the selection of mid-fiber cotton varieties, and analyzes the separation of fiber and high fiber content. It is suggested that positive hygiene can be found in pairs of hybrids and families in order to detect positive transgression, and by selecting larger samples, positive plant recombinant plants can be found. Practice is made of O-445 family, created by double hybridization on fiber yield, Range T-33-35 / 18, family O-580, created by double hybrid to improve fiber length, T-25-27 / 18 and T-54-56 / 18. the use of selection processes.
