“…There are reports where pre-harvest applications of calcium did not affect the TSS in blueberry fruits (Lobos et al, 2021), apples (Fallahi and Mahdavi, 2020) or pepper (Marín et al, 2009); however, according to Rahman et al (2016), fruits generally present a higher amount of TSS when they do not receive calcium applications, as seen in this research, where the TSS value was 15.7% without calcium applications but, when calcium was applied in doses of 100 kg ha -1 , the TSS value was 15.3%. Also, Khan and Ali (2018) reported that the results of preharvest Ca applications, in many cases, are erratic and even contradictory, possibly because of genotypic differences among varieties and fruit species or Ca concentrations and formulations used (Lara, 2013).…”

Cape gooseberry fruits have positioned in the world market due to their excellent nutritional characteristics, because they are an ideal food that contributes to raising the defenses of the human body and helps it to face diseases such as COVID-19, they are also a natural source of antioxidants and anticancer agents. In order to avoid the physiopathy of cracking in cape gooseberry fruits, these were characterized at harvest time, coming from greenhouse plants irrigated with different applications of water levels and irrigation frequencies, as well as different calcium doses, in a design of randomized complete blocks with 12 treatments. The blocks were the irrigation frequencies (4, 9 and 14 days), while the treatments were the combination of four irrigation coefficients (0.7, 0.9, 1.1 and 1.3 of the evaporation of the tank class A) and three doses of calcium (0, 50 and 100 kg ha-1). The plants were sown in 20 L pots with peat moss substrate. Fruits were harvested at the color stage 5 and 6 of the calyx, from 19 weeks after transplanting. The different water levels and irrigation frequencies did not significantly affect the firmness of the cape gooseberry fruits, but there was a strong tendency that cracked gooseberry fruits are less firm than healthy fruits. As the irrigation coefficient increased, the total soluble solids (TSS) increased while the total titratable acids (TTA) decreased. Irrigation frequency of 14 days generated fruits with higher TSS and pH values. The calcium doses did not affect the calcium concentration in the fruits or the TSS, TTA and pH values. Therefore, it can be concluded that incremented irrigation coefficients (up to 1.3) increase the quality of cape gooseberry fruits.

“…Ethylene biosynthesis pathway is composed, essentially, of three phases, starting with the formation of S-adenosyl-L-methionine (SAM; phase 1), followed by the transformation of SAM into 1-aminocyclopropane-1-carboxylic acid (ACC; phase 2), which serves as a substrate for ethylene formation (phase 3) (Borjas-Ventura et al, 2020). The AVG inhibit the conversion of SAM into ACC in phase 2 (Khan Ali, 2018). Nevertheless, as expected, the effects of AVG depend on the dosage and its frequency, as well as on the cultivar under study (Arruda, 2017;Loría, 2016).…”

La piña (Ananas comosus) es una especie muy cultivada en diferentes países tropicales. Sin embargo, su floración natural es un evento fisiológico que puede dificultar la labor de cosecha, trayendo consigo problemas económicos. En tal sentido, este trabajo tuvo como objetivo determinar el efecto de la Aviglicina sobre la floración de piña cv. ‘MD2’ en la selva central del Perú. Se estudiaron tres dosis (150 mg · L-1, 250 mg · L-1 y 350 mg · L-1) de Aviglicina (AVG) (producto comercial Retain 15 %), con 6 y 11 aplicaciones. En general, los resultados confirman la aparición de floración natural (FN) en condiciones de Satipo. Las altas dosis de AVG (250 mg · L-1 y 350 mg · L-1) inhibieron la aparición de las inflorescencias durante casi todas las evaluaciones, especialmente con once aplicaciones comparadas con el tratamiento sin AVG ni TIF (Tratamiento de inducción floral) (FN). Asimismo, FN presentó tres periodos con tasas relativa de aparición de inflorescencias (TRAI) diferentes, siendo la primera la que tuvo mayor TRAI y mayor duración (42 días). Finalmente, se concluye que la aplicación de AVG tuvo un efecto significativo en el retardo de la aparición de las inflorescencias, motivo por el cual se sugiere su aplicación en el cultivo de piña. Sin embargo, son necesarios más estudios para seguir profundizando el conocimiento sobre el manejo de este regulador de crecimiento.

“…Interestingly, in leaves with 100% damage (frost injury), the inhibitory effect of AVG was much weaker and similar to the effect of propyl gallate (PG), a free radical scavenger [ 97 ]. Preharvest application of ethylene inhibitors can be used for modulation of post-harvest fruit and vegetable quality [ 98 ]. Similarly, ethylene scavenger techniques are often used in delaying the ripening of fruits and vegetables [ 99 , 100 ].…”

The physiological state, i.e., senescence or juvenility, of plants and plant organs can have strong effect on their reactions to pathogen attacks. This effect is mainly expressed as changes in the severity of disease symptoms. Generally, necrotrophic pathogens cause more severe symptoms on senescent than on juvenile plants, while biotrophs prefer juvenile tissues. Several factors of senescence have opposite effect on the two pathogen groups, such as decreased photosynthesis, decreased antioxidant capacity, remobilization of nutrients, changes in plant hormonal network, and in fluidity of cell membranes. Furthermore, senescent tissues are less tolerant to toxins and to cell-wall-degrading enzymes. On the other hand, pathogen infection itself has significant effect on the physiology of plants depending on the lifestyle of the pathogen and on the compatibility or incompatibility of the interaction with the plant. There are several possibilities to manipulate the physiological state of plants in order to improve their biotic and abiotic stress tolerance, such as removal of the terminal bud or high doses of nitrogen, external application of cytokinins or of inhibitors of ethylene action, as well as by spontaneous or directed mutation, in vitro selection, or manipulation by various transgenic approach. Even application of mycorrhiza can inhibit the senescence process of plants and improve their tolerance to stresses.
