Item Hass avocado behavior on different rootstocks and response to paclobutrazol applications(Universidade Federal de Viçosa, 2022-12-21) Castro, Guilherme Dumbá Monteiro de; Santos, Carlos Eduardo Magalhães dos; http://lattes.cnpq.br/9028126274143041The world market for the consumption and production of fruits and vegetables, as well as several other sectors, has undergone rapid changes, mainly due to the pandemic caused by the Covid19 virus. Consumers are showing more interest in healthy eating. The avocado has proven to be one of the most prominent fruits regarding new eating habits, especially the Hass cultivar. The change of habits even before the start of the pandemic in 2020, and because avocado has many health benefits, world consumption of avocados increased from 3.5 million tons in 2007 to 5. 9 million tons in 2018. Its average consumption increased in Brazil from 600 grams/inhabitant/year, in 2016, to 900 grams in 2018. Brazil has proven to be an essential player in the avocado chain, with its planted area increasing yearly and a high capacity to supply quality products at different times. Despite this, productivity levels are still below the world average. The Cerrado Mineiro region has faced severe falls in its plant productivity over the years. It justifies the need to develop research with the most produced cultivars in the country. The present study aimed to analyze two scientific articles that can be used as a basis for new technology development for the Alto Paranaíba region, one of the largest avocado producers in Minas Gerais. The first article determines more suitable rootstocks for the Hass canopy cultivated in the Alto Paranaíba region through physiological, biometric, and production analyses, allowing better decisions in the orchard implantation. All Hass plants showed different physiological behavior when grafted in distinct cultivars without showing significant differences in the productivity factor. The Ouro Verde and Hass proved to be the most promising for use as a rootstock in the Minas Gerais cerrado. The second article analyzed the avocado Hass plant cultivated in eight different doses of paclobutrazol, 0,0; 0,5; 0,25; 0,75; 0,85; 1,0; 2,0 and 3,0 g.m-1, application in soil and foliar, in four application months, December 2021, March, May, and June 2022. It analyzed shoot length, panicle number and type, and fruit number. Paclobutrazol could reduce the shoot length in all applications; in the soil, the product also improves the plant's total panicles and determinate panicles number, possibly leading to more fruits. The development and continuation of the studies carried out in this thesis are essential; we can increase the production of the state of Minas Gerais, also helping in the national output. We will be able to produce with more quality and quantity, using methods not yet used worldwide and developing technologies for avocado producers consciously and sustainably.
