No full textObjectives: Currently, Mexico is the second-largest producer of red raspberries in the world. A steady increase in consumption, quality demands from the international market and its high value call for practices that can enhance production and quality of this crop. A viable option is the use of bioregulators, and this study evaluated the effects of prohexadione calcium (P-Ca), gibberellins A4/7 (GA4/7) and 6-benzylaminopurine (6-BAP) on the growth, development and quality of raspberry cv. UANC-2022.
Study Design: The study was set up under a completely randomized block design with a 4x3 factorial arrangement. The first factor was the bioregulators used (P-Ca, GA4/7, 6-BAP and the combination of GA4/7+6-BAP) and the second factor was the number of applications.
Location and Duration of the Study: Conducted at the Department of Horticulture, Universidad Autónoma Agraria Antonio Narro, in Saltillo, Mexico, during the period March to October 2022.
Methodology: Treatment applications were carried out at three specific times during the growing cycle, with a first application made one day after pruning (DAP), the second at 48 DAP and the third at 70 DAP. All treatments were applied to the foliage.
Results: P-Ca temporarily reduced lateral shoot growth (LSG), improved reproductive development and yield, and increased fruit quality. GA4/7 promoted LSG, reproductive development, yield, and improved fruit quality. 6-BAP enhanced fruit quality. The combination of GA4/7+6-BAP increased LSG in the early weeks and improved fruit quality.
Conclusion: The bioregulators GA4/7, 6-BAP and P-Ca bring targeted benefits to growth, development and fruit quality, making them a viable management practice that can be implemented in the production of raspberries

No full textIn order to improve germination and vigour, the current study was conducted using three carrot varieties viz. Carrot Florence (G1), Deb Kuroda-1 (G2), and Deb Kuroda-3 (G3), and various concentrations and durations of PEG-6000, including 0.1 MPa for 24 hours (T2), 0.1 MPa for 48 hours (T3), 0.25 MPa for 24 hours(T4), 0.25 MPa for 48 hours (T5), 0.40 MPa for 24 hours (T6), and 0.40 MPa for 48 hours (T7), non-primed seeds (T1). A pre-sowing technique called seed priming produces a physiological environment that promotes more efficient seed germination. The experiment was carried out in the Department of Seed Science and Technology\u27s seed testing lab at the BCKV, Mohanpur, Nadia, West Bengal, India. According to the experiment\u27s results, seeds treated with 0.25 MPa PEG-6000 soaking for 48 hours produced the best results among treatments over genotype; these seeds showed notably greater potential than seeds treated with other priming concentrations and durations. Deb Kuroda-3 is the best from a germination perspective, and Deb Kuroda-1 is the best from a vigour perspective. The best results were clearly obtained with a 0.25 MPa PEG-6000 soaking duration of 48 hours for seed quality parameters like germination energy (47.273), seedling Vigour Index-I (639.032), and germination index (5.503). Therefore, to improve seedling establishment, PEG-6000 0.25 Mpa pre-sowing treatment for 48 hours is recommended for carrot

Genetic Variability for Quantitative Traits in Bottle Gourd (Lagenaria siceraria (Mol.) Standl.)
No full textThe selection of the superior traits in plants is one of the important phenomena of natural selection. Genetic variability in plants is also considered one of the important bases of natural selection, which can open a new way of trait selection in crops. The present investigation was carried out during Zaid 2022, with the aims of estimating genetic variability and working out heritability in a broad sense and genetic advance in per cent of mean to determine the scope of improvement among 30 genotypes, including a check variety Narendra Pooja in bottle gourd. The experiment was sown on 10 March 2022. All the recommended agronomic package of practices and plant protection measures were followed to raise a good crop. Observations were recorded on 16 quantitative characters. The highest phenotypic and genotypic coefficient of variation was observed for the number of seeds per fruit, followed by seed weight per fruit, seed yield per plant, internodal length, vine length, mature fruit equatorial circumference, and node at first pistillate flower appearance. Heritability ranged from 20 per cent (days to 50% staminate flower anthesis) to 99.50 per cent (seed weight per fruit), and genetic advance in per cent of mean ranged from 3.28 per cent (days to 50% staminate flower anthesis) to 157.27 per cent (Number of seeds per fruit). The estimates of high heritability seed yield per plant, 100 seeds weight, number of seeds per fruit, seed weight per fruit, inter-nodal length, number of nodes per vine, number of primary branches, vine length, mature fruit equatorial circumference, mature fruit polar length, and edible fruit equatorial circumference. Therefore, from the above obtained results, it is possible to deduce that the characteristics will result in successful crop improvement for better seed yield and yield-attributing characters. The characters showing high heritability, coupled with genetic advances, provide a broad way for the improvement in genotypes for specific characters. The information may further help the breeders in formulating appropriate strategies aimed at getting higher yields and character improvement in bottle gourd
