Plectranthus scutellarioides (L.) R. Br. is part of the Lamiaceae family and is commonly known as coleus, due to the genus denomination in the past. This ornamental plant species has been gaining importance in the floristic industry due to the great number of exotic cultivars available in the market. Coleus commercial exploitation by seeds is held up by genetic instability, which makes it usually being propagated through semi-hardwood stem cuttings and leaves have great importance in stem cuttings adventitious rooting. The objective of this study was to evaluate the presence or absence of apical leaves and the use of indolebutyric acid (IBA) in coleus stem cuttings rooting. Semi-hardwood coleus stem cuttings with 6 cm long were prepared with or without apical leaves, and then treated with hydroalcoholic solutions (50% v v-1) of 0, 1000 and 2,000 mg L-1 IBA. The propagules were planted in tubes containing vermiculite and kept for 30 days in a greenhouse under intermittent misting (24 ± 2 °C, Relative Humidity 90%) until final evaluation. The experiment was conducted in a completely randomized design, in a 3x2 factorial scheme (3 IBA concentrations x presence and absence of apical leaves). The rooting was evaluated after 30 days. Stem cuttings with and without apical leaves has 100 and 57% rooting, respectively. Stem cuttings rooting did not vary according to IBA concentrations. Roots length and number were higher in stem cuttings with apical leaves in comparison to leafless ones, regardless IBA concentrations. On average, 97.7% sprouting was observed in cuttings with apical leaves, significantly higher rates when compared to the average of 2.2% on leafless cuttings. The presence of apical leaves is fundamental for coleus stem cuttings rooting and the use of IBA is not required for this species propagation.

In the search for more efficient techniques for the propagation of peach cuttings, this study aimed to evaluate the rooting of hardwood cuttings of peach rootstock genotypes under different indolebutyric acid (IBA) concentrations. In the winter of 2016, the basal end of cuttings of genotypes 1701-1, 1701-2, 102-1, 102-2, 202-1 and 'Okinawa' were dipped into solutions with five concentrations of IBA (0, 1000, 2000, 3000 and 4000 mg mg L-1) for 5 seconds. The cuttings were then placed in sand in plastic trays and kept in a mist chamber. The experiment was arranged in a 6x5 factorial, completely randomized design, with 5 replications, and each plot consisted of eight cuttings. After 59 days, the variables related to rooting and root quality were evaluated. Genotypes 102-1 and 202-1 showed high adventitious rooting potential in hardwood cuttings, with 76.8 and 66.5% of rooting, respectively. The concentration of 2000 mg.L-1 of IBA acid can be recommended for the treatment of hardwood cuttings of the tested rootstocks for propagation in the winter.

Mate (Ilex paraguariensis A. St.-Hil) is an arboreal species of great economic and socio-environmental importance, which presents difficulties in the adventitious rooting process. The rhizogenic competence of vegetative propagules of mate can be attained by coppicing, but the factors that influence the success of this technique have not yet been elucidated. Therefore, the aim of this study was to evaluate the effects of the stock plant, time of shoot collection, treatment with indolebutyric acid (IBA) and diameter of vegetative propagules in the adventitious rooting of cuttings from shoots induced by coppicing of selected adult plants of mate. Shoots produced from coppiced 13SM01 and 13SM05 stock plants were collected at different times of the year to prepare single-bud cuttings. The cuttings were measured as their diameter in the central portion and treated with 0 and 3000 mg L-1 of IBA. After 60 days, cuttings were evaluated to determine survival and rooting percentages, number of roots, and length of the three largest roots. A completely randomized design was used in a 4 × 2 × 2 × 13 (collection times x stock plants x IBA treatment x diameter classes) factorial scheme with 15 replications. Competence for adventitious rooting was highest for stock plant 13SM05. Cuttings collected in November and February had the highest rooting percentages, without the need of IBA treatment. Cuttings from 13SM01 and 13SM05 with diameters smaller than 0.636 cm (classes 1 to 6) and smaller than 0.712 cm (classes 1 to 7), respectively, had the highest rooting percentages and differed significantly from cuttings with larger diameters. Thus, the results of the present study indicate that stock plants, time of shoot collection, and diameter of vegetative propagules influence adventitious rooting competence of mate cuttings from coppicing adult plants. Rooting of mate cuttings with lower rhizogenic competence is influenced by the application of 3000 mg L-1 of IBA.

The number of studies on edible coatings that are used for extending the shelf life of fruits has steadily increased. For this purpose, it is necessary to choose raw materials with characteristics that maintain product quality. The objective of this study is to evaluate the effect of coatings of Chlorella sp. on the post-harvest conservation of ‘Tommy Atkins’ mango fruits. The experiment was conducted using a completely randomized design, and spray treatments (T) with 0%, 1%, 2%, 3%, or 4% of Chlorella sp. were applied to the fruits. After the treatments, the fruits were stored for 28 days (21 days at 10 °C and 42% relative humidity and 7 days at 25 °C and 42% relative humidity), and were analyzed on day 28. There was higher pulp firmness in fruits as the concentration of Chlorella sp. was increased, and the concentration of ascorbic acid was comparatively higher (22.17%) in fruits treated with 3% Chlorella sp. The percentage of soluble solids and the soluble solids/titratable acidity ratio were decreased as the coating concentrations were decreased. The use of Chlorella sp. at 1% and 2% allowed fruit maturation without compromising fruit quality attributes during the 28-day storage period.

Abstract The discovery of auxins as plant growth regulating chemicals in the 1930s and their ability to stimulate adventitious rooting in stem cuttings marked a major milestone in the modern history of plant propagation. Basic and applied research conducted during the past 70 years has provided information regarding absorption and translocation of auxin in cuttings, as well as the effects of timing of auxin application, methods of auxin application, type of auxin, and concentration of auxin on the rooting response of cuttings. The basal quick-dip method, the powder application method, and the dilute soak method have been the most commonly used methods for applying auxin to cuttings in commercial horticulture over the past 7 decades, with the first two methods still in common use today. In addition, a wide variety of other auxin application methods have been reported beginning in the 1930s and continuing to the present. Some of these methods remain primarily of historical interest, several find limited use in commercial horticulture, and others show potential for greater use in the future. Opportunities exist for further development of auxin application techniques that can enhance plant quality, efficiency and productivity of the cutting propagation process, and worker safety. This review provides horticulturists, from the academic researcher to the commercial propagator, with an exploration of auxin application methods over the past 70 years, along with an examination of the physiological response of cuttings to applied auxin and an overview of issues leading to future opportunities.

Oyster mushrooms have the conditions of growing at low temperatures and high relative humidity, so when you want to cultivate it is needed an appropriate environment for the growth and development of oyster mushroom. Banjarbaru City tends to have high temperatures with a relative humidity that tends to below. This is quite different from the requirements for growing oyster mushrooms which require low temperatures with relatively high humidity. One of the easiest and cheapest methods to maintain temperature and relative humidity to remain ideal and appropriate is to water the surrounding oyster mushrooms growing media, so knowledge of the most appropriate and ideal watering frequency for growth and development of oyster mushrooms is needed. The environmental design used was a Completely Randomized Design (CRD), a single factor with 4 treatments, 5 replications, so that 20 experimental units were obtained. The treatments are p1 = once watering per day, p2 = twice watering per day, p3 = three times watering per day, p4 = four times watering per day. The result showed that the watering frequency gave a real difference to the growth time of oyster mushroom shoots and the wet weight of oyster mushrooms. The best treatment in accelerating the time to grow oyster mushroom shoots and increasing the wet weight of oyster mushrooms is the treatment of watering frequency four times per day.

ABSTRACT The objective of this work was to evaluate the effect of six indole-3-acetic acid (IAA) concentrations and three immersion times in IAA solutions on the vegetative propagation of Spondias dulcis and Spondias tuberosa by stem cuttings. The experiment was conducted in a greenhouse, using a completely randomized design, with a 6×3 factorial arrangement consisting of six indole-3-acetic acid concentrations (0, 2, 4, 6, 8, and 10 g L-1) and three immersion times (8, 16, and 24 seconds), with ten cuttings of S. dulcis and S. tuberosa per plot, and three replications. Percentage of surviving cuttings, and percentage of rooted cuttings, number of leaf buds, number of roots per cutting, root length, and total fresh weight were evaluated at 180 days after planting. Data were subjected to analysis of variance by the F test and to regression analysis. Vegetative propagation from woody cuttings of S. dulcis is not viable to produce seedlings, thus, new studies on this technique for this species are needed. Vegetative propagation from woody cuttings of S. tuberosa is satisfactory, but with low efficiency for improvement and emergence of new shoots and roots; it is more effective when using a concentration of 10 g L-1 of indole-3-acetic acid and immersion time in the solution of 16 seconds.

Buxus sempervirens L., popularly known as boxwood, is a woody shrub widely used in gardening and landscaping. One of the most important factors for B. sempervirens commercial production is its propagation. The objective of this study was to evaluate the effect of indolebutyric acid (IBA) concentrations on the adventitious rooting of semihardwood stem cuttings of the species. Branches with new shoots were collected from stock plants with approximately 17 years of growth. Stem cuttings of six centimeters in length with two leaves in the upper region were made with a straight cut at the apex and a bevel cut at the base. Cuttings bases were immersed for 10 seconds in hydroalcoholic solutions (50% v v-1) with IBA at 0, 1500, 3,000 or 6,000 mg L-1. The cuttings were evaluated at 64 and 116 days after planting. Rooting, mortality, callus formation and sprouting percentages as well as root number and root length were measured. At 64 days, no significant percentage of rooting was observed in B. sempervirens stem cuttings and sprouting and callus formation were not significantly affected by the treatments. Keeping the cuttings in the greenhouse for 116 days led to rooting rates up to a 97.5%, with no statistical difference among treatments. Root lengths and root numbers did not differ as a function of treatments. The required period for B. sempervirens stem cuttings rooting is around 116 days; IBA application does not affect rooting, survival or sprouting of B. sempervirens stem cuttings.

Orchid is an ornamental plant, including the Orchidaceae tribe, which is widely favored among the ornamental plant community because it has high economic value, unique shapes, attractive colors and longer-lasting blooming flowers, one of which is a Phalaenopsis orchid. One of the efforts to accelerate the vegetative phalaenopsis can be done with the application of the NAA hormone and leaf fertilizers such as Gandasil fertilizer and Growmore fertilizer. The aims of this research to determine the effect of NAA, Gandasil and Growmore fertilizer types on the growth of hybrid Phalaenopsis orchids. The study was conducted at Greenhouse Jalan Tlogomas Kec. Lowokwaru, Malang City, for 5 months. The experiment was carried out using a factorial Completely Randomized Design (CRD) consisting of 2 factors namely, the factor I: NAA concentration: control 0 ppm (N0), 100 ppm (N1), 200 ppm (N2), and 300 ppm (N3). Factor II: leaf fertilizer, Growmore (P1) and Gandasil D (P2). Variables observed included: when buds appeared, leaf length, leaf width and percentage of live plants. The results showed that there was an interaction between the concentration of NAA and the type of leaf fertilizer on the emergence of shoots. When the fastest shoots appear at 100 ppm NAA, Growmore fertilizer (N1P1), which is 29 days. The NAA hormone influences the increase in leaf length and leaf width until 16 weeks of age. The best growth of hybrid Phalaenopsis was obtained at the administration of 200 ppm NAA with an increase in leaf length of 1.49 cm and an increase in leaf width of 1.06 cm until 16 weeks of age. Growmore and Gandasil D did not affect the vegetative growth of hybrid Phalaenopsis Orchid plants.
