“…Cytokinins can induce high proliferation and cell division; that is, they increase the multiplication rate of plants [52,53]. Likewise, they cause the elongation of the roots, in addition to an increase in the production of shoots [52,54].…”

Sechium compositum (Cucurbitaceae) is a wild species that is distributed in the Soconusco region, Chiapas, Mexico, and the border with Guatemala. This species has an intangible biochemical value resulting from the pharmacological relevance of its secondary metabolites. However, as a consequence of the lack of knowledge about its importance, it is being displaced from its habitat at an accelerated rate, incurring the risk of genetic loss. Therefore, an in vitro culture protocol with two experimental phases was evaluated to propagate, conserve, and regenerate this species. The first phases considered the shoot propagation, adding seven concentrations (0.1, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2 mg mL−1) of 6-benzylaminopurine (BA) and thidiazuron (TDZ) and evaluating the number of buds and shoots and the shoot height. The best multiplication response was recorded with 0.1, 0.2, 0.4, and 1.0 mg L−1 of BA and 0.1 mg L−1 of TDZ, as well as the MS base culture medium. The validation of the results of the first phase (0.1 mg L−1 of BA) was compared with the MS in an independent experiment against the control (n = 50 repetitions), obtaining a height of 52 mm, 1.36 shoots, and 9.22 buds, suggesting that this concentration is adequate for the purpose, surpassing the MS control (MS culture medium alone). Of the total volume of roots obtained with packed bud structure in the previous experimental sample, it was reduced to 14% (n = 50). The second phase consisted of inducing callus formation from stem and leaf explants through the addition of 0.5, 1.0, and 2.0 mg L−1 of TDZ and 2,4-Dichlorophenoxyacetic acid (2,4-D) to the medium. Callus induction in S. compositum was better when using the stem in a medium with 2.0 mg L−1 of 2,4-D with a value of 97.8% around the explant. The addition of 500 mg L−1 of polyvinylpyrrolidone (PVP) is also suggested to reduce oxidation. This protocol represents a significant advance in the conservation, multiplication, and callus formation of S. compositum and contributes to its rescue and revaluation in the face of the danger of extinction.

“…Plant growth regulators with auxin effect such as indole-3-propionic acid, naphthaleneacetic acid, 2,4-dichlorophenoxyacetic acid, and 2,4,5-trichlorophenoxyacetic acid are synthetic organic substances considered agrochemicals, and they are used to promote seed germination, rooting of cuttings, sprouting of differentiated buds, fruit setting, delaying the physiological maturity of fruits, and preserving the quality of some fruits in post-harvest [9,11]. Exogenous application of auxins to plants in high concentrations induces vegetative growth by inhibiting flowering, growth, and fruit development [13].…”

The technological levels used to reduce fruit losses in post-harvest are closely linked to those used in pre-harvest. Applications of phytohormones, growth regulators, and calcium to fruit in pre- and post-harvest are viable alternatives to increase and preserve quality attributes. Knowledge of the action and response of fruits to the exogenous application of different phytohormones, growth regulators, and calcium in pre-harvest are fundamental when considering that fruit quality is acquired at this stage and that the purpose of post-harvest technology is to preserve fruit quality. This chapter describes research carried out to evaluate the response of different fruits to the application of phytohormones, phytoregulators, and calcium, which showed favorable responses in increasing fruit quality in pre-harvest and preserving quality in post-harvest.

“…A reprodução sadia e uniforme de culturas de interesse agronômico tem sido o objeto de estudo em diversas pesquisas nos últimos anos. Os extratos vegetais exercem um papel fundamental no desenvolvimento e fertilização de culturas, atuando em funções celulares, metabólicas, refletindo no tempo de produção, maturação de frutos, concentração de agentes patógenos, etc., contudo, também podem apresentar um efeito negativo e inibir o desenvolvimento de algumas espécies (ALCANTARA-CORTES et al, 2019;GUIDOTTI et al, 2013).…”

A crescente preocupação mundial com os impactos ambientais, potencializados pelo uso excessivo de defensivos e fertilizantes químicos, tem sido o ponto de partida para a busca de métodos alternativos de desenvolvimento do setor agrícola. Nas últimas décadas, pesquisadores têm observado o potencial de diversas espécies de plantas na germinação de sementes, desenvolvimento vegetal, além do controle de pragas e doenças em espécies de interesse agronômico. Os chamados extratos vegetais podem ser obtidos de distintas maneiras e utilizados para potencializar ou inibir características específicas de outras plantas através de seu efeito alelopático. Deste modo, objetivou-se com essa pesquisa reunir informações, através de revisão bibliográfica, a respeito da utilização e efeito de extratos vegetais na agricultura. O estudo foi realizado através do uso de pesquisa bibliográfica, com revisão de literatura. A temática da pesquisa foi o uso e o efeito de extratos vegetais na agricultura, sendo aderidas 35 fontes bibliográficas. O levantamento foi realizado em periódicos, sites, revistas e livros. As fontes utilizadas foram selecionadas de forma criteriosa, analisando resumos e palavras-chave. Na construção do desenvolvimento do trabalho, foram abordados os tópicos: Extratos vegetais no controle de pragas; Extratos vegetais no controle de doenças; Extratos vegetais na fertilização das culturas; e Extratos na germinação de sementes. Diante aos resultados da pesquisa, é possível concluir que os extratos vegetais podem impactar o desenvolvimento vegetal de inúmeras formas, contribuindo das mais diversas formas com culturas de espécies de interesse agrícola.
