ABSTRACT: The structure of the root system of the conilon coffee tree has improved over the years through propagation, genetic, and agronomic studies in response to demands for improvements in plant development, production, and survival of the species. Scientific research plays an important role in generating technologies and the security of applications. However, there is a need to refine the content generated to analyze discoveries and trends on the subject. Therefore, the present study conduct a bibliometric review and analysis on the main contributions of relevant studies, researchers, organizations, and countries in academic research on the rooting of Coffea canephora in the Web of Science (WOS) database. Data from the WOS database published between 1982 and 2021 and systematized in the VOSviewer software showed a set of 92 articles, the majority of which originated in Brazil and France, with the main groups being the Brazilian Agricultural Research Corporation, the Federal University of Viçosa, and CIRAD. The study was divided into five areas: genetic diversity, asexual propagation, nematology, tolerance to water stress, and micropropagation. However, in the context of climate changes and its impact on the production and longevity of Brazilian coffee farming, research focused on the root system has increased significantly, integrating it into lines that explore and integrate topics such as climate risk, water management, drought tolerance, and drip irrigation, including reflections on the performance of coffee agronomy.

Abstract The objective of this work was to verify if D-limonene in vitro presents inhibitory action on the mycelial growth of Colletotrichum spp. and antimicrobial activity against Enterococcus faecium and Escherichia coli, as well as to evaluate the effect of its concentrations on papaya disinfestation in the post-harvest process. For the in vitro tests, fungi were isolated from papaya fruit infected with anthracnose. For this, fruit fragments were disinfected and transferred to Petri dishes. Another test was carried out in vitro, to evaluate bactericidal activity, by for adding D-limonene to the suspension of the tested bacteria. Fruit physicochemical quality and disease incidence were evaluated. The application of D-limonene inhibited the mycelial growth of Colletotrichum spp. in vitro, with an increasing effect at increasing concentrations and a decreasing effect with time of product application. D-limonene was effective in inhibiting E. faecium and E. coli. There was no significant interaction between D-limonene rates and storage time for fruit quality or for disease incidence in ex vitro studies. D-limonene can be applied to papaya at postharvest, as it does not affect fruit quality and controls the growth of phytopathogens in vitro.

ABSTRACT The objective of this study was to evaluate the physiological quality of seeds from early and late maturing Coffea canephora clones, aiming to identify the ideal harvest time. The fruits were collected every two weeks from 188 days after anthesis (DAA) and characterized as green, cane green, cherry, raisin and dry. The seeds were evaluated for water content, germination percentage, normal and abnormal seedlings, nongerminated seeds and dead seeds, vigor index, hypocotyl lenght, and root length. Seed germination of the early maturing clone started at 202 DAA, while that of the late maturing clone started at 230 DAA, with both clones showing a water content of 63% and a dry mass of 37%. Although the optimum harvest point was identified at the cherry ripening stage, it was found that the late maturing clone showed a more pronounced variation in the maturation process, directly impacting the physiological quality of the seeds. Furthermore, a significant correlation was observed between the maturation stages and the physiological quality of the seeds. For the early maturing clone, the maximum physiological quality was recorded at 244 DAA, corresponding to 80% of fruits at the cherry stage, while for the late maturing clone this point was reached at 326 DAA, with 98% of the fruits ripe. time 18 DAA (DAA green percentage seedlings index lenght length 20 23 63 37 37% stage process Furthermore 24 80 32 98 ripe 1 2 6 3 8 9

ABSTRACT Fusarium is the main disease of black pepper (Piper nigrum L.) in Brazil, and grafting using resistant rootstocks can be a sustainable management strategy. Several wild Piper species have been considered resistant to infection. However, further studies on the grafting process are needed to generate a safe technical recommendation for farmers. This research was carried out with the objective of evaluating the initial compatibility of grafting through the interaction between two techniques (top cleft and side cleft) and six rootstocks. The P. nigrum ‘Bragantina’ was grafted onto four wild Piper species (Piper aduncum Link, Piper tuberculatum Jacq., Piper marginatum Jacq., and Piper hispidum Kunth) and two black pepper cultivars (‘Kottanadan Broto Branco’ and ‘Bragantina’-homograft). P. tuberculatum and P. marginatum were incompatible with P. nigrum ‘Bragantina’ in the two grafting techniques. There was total suppression of leaf development with incompatible rootstocks inside cleft grafting. The wild rootstocks had twice as many shoots at the base of the seedling than the cultivars in the top cleft grafting. Side cleft grafting was able to suppress by half the shoots at the base of the rootstock, while the aerial part was maintained. Top cleft grafting provided greater survival, shooting, and leaf emission, which was more evident when using P. aduncum species as rootstock, reaching practically twice the shooting (59.3%) in comparison with the side grafting (30.6%). Therefore, the top method and the use of P. aduncum as rootstock for the production of grafted black pepper seedlings is recommended. L.

ABSTRACT One of the various seaweed species with biostimulating properties is Lithothamnion sp., a calcareous seaweed recognized for its nutritional attributes. This review article aimed to gather information on Lithothamnion sp. and its applications in agricultural cultivation, focusing on identifying and analyzing its biostimulant effects. The practical use of this biostimulant in farming has been confirmed by studies highlighting its efficiency, which varies according to the source material (deposit and particle fraction), application methodology (dosage, methods and frequency) and specific crop (genotype and development stages). Lithothamnion sp. is notable for promoting vegetative growth and has established itself as an invaluable biostimulant in producing seedlings of various species. Its application, either via soil or by foliar methods, has led to improvements in the yield and quality of vegetables, fruits, oilseed crops, grains and forage plants. Although the underlying mechanisms need further investigation, the results suggest that Lithothamnion sp. contributes to amplifying photosynthesis, water-use efficiency and phytoalexin production. sp attributes cultivation effects deposit fraction, fraction , fraction) dosage, dosage (dosage frequency genotype stages. stages . stages) vegetables fruits crops plants investigation photosynthesis wateruse water production
