In cotton seeds the radicle has 12% moisture content which makes it possible to prepare freeze-fracture replicas without fixation or cryoprotection. For this study we have examined replicas of unfixed radicle tissue fractured at room temperature to obtain data on organelle and membrane structure.Excised radicles from seeds of cotton (Gossyplum hirsutum L. M-8) were fractured at room temperature along the longitudinal axis. The fracture was initiated by spliting the basal end of the excised radicle with a razor. This procedure produced a fracture through the tissue along an unknown fracture plane. The warm fractured radicle halves were placed on a thin film of 100% glycerol on a flat brass cap with fracture surface up. The cap was rapidly plunged into liquid nitrogen and transferred to a freeze- etch unit. The sample was etched for 3 min at -95°C to remove any condensed water vapor and then cooled to -150°C for platinum/carbon evaporation.

The article reviewed the certification and quality control of the technological process for the production of vegetable oil. There is a procedure for packaging, quality control of products, determination of quality indicators and quality control of finished products. The procedure for using refined cottonseed oil and its varieties, the requirements for placement and storage of vegetable oils, as specified in the regulatory documents, the quality control of vegetable oils and other solutions for cottonseed oil are provided. The gas analyzer shows a solution for measuring the amount of solution by painting the tubes of a mixture of gas and air in oil. Detailed information on the production of vegetable oils, the cost of raw materials, the level of fat content of cotton seeds and the methods used to produce oil from cotton seeds. Methods for certification of vegetable oils, types of quality control, methods of testing and quality determination are presented. It was shown that the procedure for refined production of cottonseed oils and their types, as well as the state of the product classification of products based on the method of producing vegetable oils for consumer purposes, analysis of the sequence of refined oils and refining processes.

And Control

Insecticide-treated cotton seeds can pose risks to Apis mellifera Linnaeus, 1758 populations during crop establishment if chemical residues reach these insects near agricultural fields via dust drift produced during planting. However, the treatment of seeds with insecticides is essential to protect cotton plants from damage caused by pests, including thrips and aphids. Thus, the aim of this study was to evaluate the toxic effects (acute toxicity) of soil dust from cotton fields planted with insecticide-treated seeds on A. mellifera adults using a toxicity assay developed in the laboratory. Forager honeybees were maintained in 700-ml plastic cages with 7 g of surface soil where insecticide-treated cotton seeds were sown (270 g a.i. clothianidin, 270 g a.i. imidacloprid, 210 g a.i. thiamethoxam, and 75 g a.i. fipronil/100 kg of seeds, and an untreated group). Ten bees were placed in each cage. The experimental design was randomized, with five treatments and twelve replicates. The mortality rate was evaluated during the entire assay. Data were transformed to x + 0.5  and compared with a regression analysis and contrast test. The linear regression model revealed a significant relationship between bee mortality and exposure time. The mortality rate gradually increased as time progressed in all treatments and the control group. The contrast test did not reveal significant differences between the insecticide and control groups. Thus, residues of the products tested, thiamethoxam, clothianidin, imidacloprid, and fipronil, did not influence the mortality of A. mellifera adults as a result of exposure to soil contaminated with insecticide-treated seeds.
