O delineamento experimental foi o completamente ao acaso, composto por cinco tratamentos e quatro repetições de quatro mudas cada. Os tratamentos foram as lâminas de irrigação estimadas com cinco percentuais da capacidade de retenção de água (CRA) do substrato: 50; 75; 100; 125; e 150% da CRA. As mudas foram cultivadas individualmente em vasos de 415 mL contendo o substrato comercial HS Flores®. Durante a aclimatização, as mudas foram irrigadas duas vezes ao dia e receberam adubações foliares em dias alternados. Foram analisadas as variáveis: incremento na altura da muda (IAM); incremento no número de folhas por muda (INF); incremento na área da maior folha (IAMF); ocupação de vaso (OV); taxa de fotossíntese líquida (A); carbono interno (Ci); e temperatura (Ti) e umidade (Ui) foliar. Com base nos resultados, supõe-se que as mudas de A. maricense possam apresentar evidência de resistência ao déficit hídrico. A lâmina de irrigação estimada com 150% da CRA proporciona o maior valor de IAMF. Lâminas de irrigação intermediárias, entre 100 e 125% da CRA, proporcionam os maiores valores de IAM, INF e OV.

ACLIMATIZATION OF MICROPROPAGATE PLANTLETS OF Anthurium maricense WITH DIFFERENT IRRIGATION DEPHTS 2 ABSTRACT The aim of this study was to evaluate the development of micropropagated plantlets of Anthurium maricense during the acclimatization phase in screen environment, under different irrigation depths based on percentages of water retention capacity (WRC), on the weather conditions in the greenhouse environment. The experimental design was completely randomized, composed of five irrigation depths, with four replicates and four plantlets per plot. The treatments consisted of irrigation depths estimated with five levels of water retention capacity (WRC) of the substrate: 50; 75; 100; 125; and 150% of WRC. The plantlets were cultivated in 415 mL pots with HS Flowers® substrate. During the acclimatization, all plantlets were irrigated twice a day and fertilized, on alternate days, with leaf fertilization. The variables analyzed were: plant height increment (PHI); number of leaves increment (NLI); largest leaf area increment (LLAI); pot occupation (PO); net photosynthetic rate (A); internal carbon (Ci); leaf temperature (Ti) and leaf moisture (Ui). Based on the results obtained, it is assumed that A. maricense micropropagated plantlets may present evidence of resistance to water deficit. The estimated irrigation depth of 150% of WRC provides the highest value of LLAV. Intermediate irrigation depth, between 100 and 125% of the WRC, provide the highest values of PHV, NLV and PO. Keywords: anthurium, ornamental plant, irrigation management.

Anthurium maricense is a tropical ornamental species with great commercial potential in the areas of landscaping and potted foliage plants. One of the main obstacles in the production of micropropagated anthurium plantlets is its slow development and/or the low survival rate of the plantlets during the acclimatization stage. The use of slow-release fertilisers (SRF) can accelerate this process; however, there are no reports in the literature concerning this practice during acclimatization of micropropagated plantlets of this species. As such, in the present study, the effects of different doses of SRF on the development of micropropagated plantlets of Anthurium maricense were evaluated during the acclimatization stage in a screenhouse. The experiment was carried out in a completely randomised design, with five treatments and four replications of four plantlets per plot. The treatments comprised doses of 0.0, 2.5, 5.0, 7.5 and 10.0 kg m-3 of the SRF Osmocote® (NPK 15:9:12) added to the substrate. The variables under evaluation were the variation in plant height, in the number of leaves and in the area of the largest leaf, pot occupancy, net photosynthetic rate, internal carbon, and leaf temperature and moisture. The use of SRF promoted better development of the micropropagated plantlets of A. maricense during the acclimatization stage. Of the variables under analysis, the variation in the area of the largest leaf is the most important, since the commercial interest of the studied species is the foliage, which was at its maximum with an estimated dose of Osmocote® of 6.40 kg m-3.

“…Even though C. scaber (orange) had the shortest vase life, it could be used as decoration for short to medium periods. Evaluating the vase life of Costus stenophyllus stems at 21 °C, Souza et al (2013) observed that the stems had a vase life of 60 days. Another important characteristic shown by the cut stems was the firmness from harvest to discard.…”

This study aimed to evaluate the vase life of floral and vegetative stems of Costaceae and describe their morphological characteristics. To evaluate the vase life of floral and vegetative stems, four and six species were used, respectively. Three cutting stages were established for floral stems. Stems were cut a few days before flower opening at stage 1, upon opening of the first flower(s) (anthesis) at stage 2, and when floral stems showed more than 15 opened flowers at stage 3. However, only two different stages were applied for each species. Floral stems were standardized with 50 cm in length, while vegetative stems were standardized with 70 cm in length. The morphological characteristics determined for floral stems included diameter of the floral stem, length of inflorescence, diameter of inflorescence and fresh mass of floral stem. For vegetative stems, we considered diameter and fresh mass. After the first evaluation, stems were maintained at 22 ºC and 53% of humidity. The total number of post-harvest days (global longevity) in which the quality of floral and vegetative stems was acceptable were evaluated. The highest vase life for floral stems at stage 1 was observed for Costus woodsoni, Costus arabicus x Costus spiralis (Costus Tropicales), and Costus scaber. Hellenia speciosa showed higher vase life at stage 3. H. speciosa showed the highest vase life and C. woodsonii the lowest values for morphological characteristics. The vase life of vegetative stems for the six species was satisfactory. Costus scaber (orange) showed the shortest longevity and Costus arabicus (yellow) longest longevity. Dimerocostus strobilaceus showed the highest values of morphological characteristics, and Costus arabicus (pink) showed lowest values. Based on the results, both floral and vegetative stems of Costaceae can be used for cutting.
