“…According to Colombo et al (2015), seeds with bigger mass present better germination capacity, standardization and seedling emergence, which is a result of the evaluated biometric characteristics; the fresh mass of fruits with the fresh mass of seeds had a direct and strong relation with the germination average time (Table 4). Based on the results obtained in this research, it is possible to deduce that the bigger the fruit fresh mass is, the bigger the seed mass will be.…”

-This study aimed at determining and correlating the main morphometric characteristics of fruits and seeds with the germination potential and vigor of eight peach rootstocks. The experimental design was completely randomized, with four replications of 50 seeds per treatment. The analyzed variables were: length, width, thickness, fresh mass of fruit and seeds, moisture content of seeds, percentage of seeds attacked by fungi and intact seeds, germination percentage, germination speed index (GSI) and mean germination time (MGT). The Capdeboscq, Aldrighi and Tsukuba 1 cultivars showed higher values of length, width, thickness and fresh mass of seeds compared to other cultivars, presenting a relationship with the later period of fruit ripening. Regardless of the fruit ripening time, the germination percentage was high, ranging between 93% and 100% for all cultivars. In addition, the fresh mass of fruits has showed a high positive correlation with the fresh mass of seeds for the eight evaluated peach rootstocks. The GSI and MGT have a high relationship with the fresh mass of seeds.Index terms: Rosaceae, morphobiometry, seeds, cultivars, peach.Correlação de características biométricas de frutos e sementes com a germinação e vigor de porta-enxertos de Prunus persica RESUMO -Objetivou-se determinar e correlacionar as principais características morfométricas de frutos e sementes sobre o potencial de germinação e o vigor de oito porta-enxertos de pessegueiro. O delineamento experimental foi inteiramente casualizado com quatro repetições de 50 sementes por tratamento. As variáveis analisadas foram: comprimento, largura, espessura, massa fresca dos frutos e sementes, grau de umidade de sementes, porcentagem de sementes intactas e infectadas por fungos, porcentagem de germinação, índice de velocidade de germinação (IVG) e tempo médio de germinação (TMG). As cultivares Capdeboscq, Aldrighi e Tsukuba 1 apresentaram maiores valores médios de comprimento, largura, espessura e massa fresca de sementes comparados com as demais cultivares, apresentando relação com o período mais tardio de maturação dos frutos. Independente da época de maturação dos frutos, a porcentagem de germinação foi alta variando entre 93% e 100% para todas as cultivares. Somado a isso, a massa fresca do fruto apresenta alta correlação positiva com a massa fresca das sementes dos oito porta-enxertos de pessegueiro avaliados. O IVG e o TMG possuem alta relação com a massa fresca das sementes.

Adenium obesum, also known as desert rose, has recently become popular in Brazil, due to its exuberance and sculptural shape. However, the production of the species in commercial scale has been facing challenges regarding propagation of hybrids by in vitro cultivation techniques, potting medium composition, irrigation and fertilization management, disease and pest control. Unlike other species sold as potted plants, there are no commercial production protocols established for Adenium, mainly due to the scarcity of technical information about this species. Thus, this technical article aimed to provide information related to the Adenium growth, in view of its commercial scale production. In addition, aspects related to floral morphology, pollination and seed production of the species, as well as, vegetative propagation strategies were discussed.

“…Allied to the potential of market expansion and to the search for differentiated products, Adenium obesum, popularly known as desert rose, is on a leading place in national scenario. It is a plant cultivated in pots and appreciated for developing swollen roots and/or shoots that serve as primary organs for water storage, and for presenting a variety of flowers shades and forms (Dimmitt et al, 2009;Brown, 2012;Colombo et al, 2015;Colombo et al, 2017).…”

This study aimed to determine NO3 - /NH4 + proportion delivered by fertigation that allows greater desert rose plants growth in pots. Plants were cultivated in greenhouse in polypropylene pots, using a mixture of sand and composted Pinus powder (1:1, v v-1) as substrate. Experimental design was completely randomized, with six treatments (control, 0/100 25/75, 50/50, 75/25 and 100/0 of NO3 – and NH4 + respectively), and ten replications. Fertigation was performed weekly in the amount of 100 mL per pot for 180 days. Variables evaluated were: shoot height, basal diameter of the caudice, number of branches, roots, leaves and caudice dry mass and macronutrient contents determination and accumulation in leaves, caudice and root. NO3 – and NH4 + proportion promoted a greater change in nutrient content in leaves compared to caudice and roots. The proportion 25/75 NO3 – /NH4 + is recommended for desert rose cultivation, as it provides the best results for most of the characteristics studied.
