Populations of Wild and Semi-Cultivated Tomatoes in Aguascalientes, Mexico
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 19, Issue 1
Abstract
During 2015 and 2016 in the CA of UAA, 5 semi-cultivated lines and 2 wild S. Lycopersicum were agronomically characterized. In the market were acquired the semicultivated and the wild were collected in San Tadeo Calvillo and El Llano Aguascalientes. The fruit was extracted from the seed, germinated in Styrofoam tray. The substrate consisted of a mixture of peat-most + coconut fiber + solarizado cattle manure + soil, as pots were used black bags of 25 cm wide by 33 cm high, a completely randomized design was used, the treatments were the genotypes with 10 Repetitions, each flowerpot was an experimental unit. When the plant was about 10 cm high, were transplanted and started counting number of days to floral button (DBF), Days to start flowering (DIF), counted the number of composite leaves (NHC), height to the first flower cluster (ARF), number of branches (NR) , number of leaves per plant (NHP) and number of leaflets per sheet (NFH). Of each plant was taken a fruit, it was weighed (GR) in electronic scale, with Vernier was measured its equatorial diameter (DE), polar diameter (DP), the firmness of the fruit was measured, it split in half and it was counted the number of locules, also it was qualified to the fruits by its form , considering the categories: flattened, round (plum shape), elongated round (pear shape) and elongated cylindrical. Finally, all the fruits were harvested per plant and weighed to obtain the yield. The plant height was statistically the same in the treatments, in number of branches were found notable differences, resulting that the wild genotypes, branched more from the base, pointing out that they show a creeping habit. The variable height to the first floral cluster was higher in the Ceresa genotype, following the Salcero, with respect to the number of floral clusters (NRF), the wild genotypes surpassed the semi-cultivated genotypes, an important agronomic characteristic because It indicates high potential of yield, which is strengthened with the results obtained with the variables number of flowers per plant (NFP) and number of fruits per plant (NFrP). In the evaluation of the fruits, the higher weight corresponded to the genotypes semi-cultivated and the lower to the wild ones due to the size of the fruit, in the variables, equatorial diameter (OF) and polar diameter (DP) highlighted the genotypes semi-cultivated compared to The wild, in terms of the number of locules the zebra genotype exceeds the rest of the genotypes, while in firmness of the fruit all the genotypes showed to be intermediate.
