Relative efficacy of different culture media for in-vitro regeneration of Aloe vera

Paper ID- AMA-02-06-2022-11433

Multiplication of a plant using in vitro culture technique greatly influences with the composition of culture media. Identification of suitable culture media is pre-requisite for getting maximum pace of micropropagation. Therefore, the efficacies of six different culture media for multiplication of Aloe vera were evaluated under in vitro condition using lateral shoot explant. An optimum level of BAP and IBA were used for shoot proliferation and root induction, respectively. Significant variation was obtained in all media types for all the characters studied. MS medium was found best for direct shoot proliferation as it induced highest number of shoot (6.30±0.23) per explant with longest shoot length (3.17±0.09 cm). The order of efficacy of different media for shoot proliferation was as MS medium > Woody plant medium > Nitsch and Nitsch medium > Whites medium > Knudson Solution-C > Schenk and Hildebrandt medium. For root induction, Woody plant medium revealed maximum number of roots (6.10±0.23) per explant, followed by MS medium. The effectiveness of different media for root proliferation were as Woody plant medium > MS medium > Nitsch and Nitsch medium > Whites medium > Knudson Solution-C > Schenk and Hildebrandt medium. Highest survival rate (85 %) during hardening and acclimatization was also obtained in Woody plant medium mediated rootlets. The identified culture media can be recommended for high frequency large scale multiplication of Aloe vera.

Textural quality and nutritional differences of Chinese cabbage (Brassica rapa ssp. pekinensis) under soil fertigation and hydroponics cultivation systems

Paper ID- AMA-02-06-2022-11431

The quality of vegetables is determined by many factors such as texture, flavor, chromaticity, and health-beneficial metabolites. Chinese cabbage is one of the most commonly consumed vegetables in Western and Asian and countries including Korea. Change in firmness of Chinese cabbage leaf tissues has not been comprehensively studied, although it serves as an important quality indicator of this product. The objective of this study was to characterize textural parameters of Chinese cabbage and to compare them in different cultivars and cultivation practices (soil fertigation or hydroponics). Soluble sugar content, leaf thickness, and chromaticity were higher in plants grown via hydroponics than in those grown via fertigation. Meanwhile, firmness and dry mass of midrib tissues showed an opposite trend in all tested cultivars. Additionally, starch contents and cell wall compounds (i.e., polyuronides and non-cellulosic neutral sugars) of midrib tissues were detected higher in plants grown via fertigation than in those grown via hydroponics. Moreover, the amounts of starch, cell wall compounds, and neutral sugars showed a positive correlation with the firmness of Chinese cabbage leaf tissues. Taken together, these data provide an informative insight for improving cultivation practices, particularly hydroponics of Chinese cabbage plants.

Multi-dimensional air flow field of air screen cleaning device

Paper ID- AMA-02-06-2022-11430

Combination mode and working parameters of the cleaning fans of the combine harvester have an important influence on the loss rate and the cleaning rate for different cleaning materials. In this paper, when centrifugal fan was acting alone and cross-flow fan acting alone, the airflow velocity at the indoor space point of cleaning room were measured on a cleaning device. The isokinetic distribution diagrams in different sections were drawn and the characteristics were analyzed. The results showed that under the action of the centrifugal fan, the airflow speed increases as the speed increases. The influence of the cross-flow fan on the screen surface is mainly concentrated on the screen tail, the increase in the speed of the cross-flow fan will expand the scope of influence.

Integrated approaches for management of spot blotch of wheat [Bipolaris sorokiniana (Sacc. In Borok) Shoem] and its effect on crop growth and yield

Paper ID- AMA-02-06-2022-11429

Integration of soil application, seed treatment and foliar spray with fungicide i.e. propiconazole provided protection of spot blotch and increased crop growth and yield of wheat. Among the treatment, the maximum germination with 99.65 % and vigour index with 795.20 was recorded in T3 treatment as seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %). The minimum disease area and disease severity was also recorded in T3 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1%), representing value as 0.46 cm2 and 10.72 % respectively which was followed by T6 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with mushroom compost (1:4) + foliar spray of propiconazole @ 0.1 %) as 0.52 cm2 and 12.65 %, respectively. The growth promoting effect of wheat crop have also been perceived from integrated approaches. The maximum with 40.15 and 27.40 cm shoot and root length were found in T3 treatment (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %). The highest grain yield with 39.01g was also obtained in T3 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %), representing 80.43 per cent increased over control.

Induced Synthesis of defense molecules in Tomato by Inorganic Chemicals against Fusarium wilt

Paper ID- AMA-02-06-2022-11428

Induced resistance using inorganic chemical have ability to reduce the disease incidence of Fusarium wilt in tomato from 78.50 to 9.12 per cent in 2015, 88.50 to 11.00 per cent in 2016 and 90.96 to 9.30 per cent in 2017 at 15 days after inoculation with the minimum calcium chloride treated plants. The tomato plant treated with inorganic chemical as inducers sensitized to produce increased level of soluble protein and total phenol contents with the maximum in calcium chloride treated tomato leaves indicating 34.83, 35.25 and 34.40mg/g in 2015, 35.93, 36.27 and 35.22 mg/gm in 2016 and 35.06, 35.96 and 33.20 mg/g of fresh leaves in 2017 at 5, 10 and 15 days of pathogen inoculation. Similarly, total phenol content was also found maximum in calcium chloride treated plant. Correlation coefficient analysis revealed that there was negative correlation between disease incidence with soluble protein (r = -0.548, -0.564 and-0.519 in 2015, -0.571, -0.570 and -0.517 in 2016 and -0.0.640, -0.643 and -0.635 in 2017) and total phenol (r = -0.576, -0.562 and -0.580 in 2015, -0.528, -0.564 and -0.536 in 2016 and -0.634, -0.521 and -0.536 in 2017) content at 5, 10 and 15 days of treatment.
