Abstract The effects of foliar spraying of sodium nitroprusside (SNP) and putrescine (Put) on rose cv. Avalanche were investigated. This experiment was conducted in a factorial trial with two factors, including SNP at four levels of 0, 50, 100 and 200 μM and putrescine at four concentrations of 0, 1, 2, and 4 mM with three replications in hydroponic conditions in the greenhouse. Some of the recorded traits included the number of leaves plant-1, leaf area, fresh and dry leaf weight, as well as determination of soluble sugars, and total protein. Also, in the post-harvest stage, the recoded traits included malondialdehyde (MDA) content, relative fresh weight, and vase life. SNP at a concentration of 100 μM was found to improve morphological traits including fresh and dry weight of leaf (4.3 and 1.4 g, respectively) compared to the control. It also increased total protein (0.85 mg g-1 FW), decreased postharvest MDA content (0.32 µM g-1 FW), and increased vase life (23.66 days) at 100 μM level, and increased leaf area (7671 mm2) and flower relative fresh weight (27.65%) at 200 μM level. Among different rates of putrescine, 4 mM putrescine was associated with higher leaf area (8056.7 mm2), fresh and dry leaf weight (4.3 and 1.3 g, respectively), soluble sugars (4.63 mg g-1 FW), lower post-harvest MDA content (0.32 µM g-1 FW), and increased duration of vase life (26 days). In general, SNP and putrescine improved rose growth parameters and post-harvest traits.

Abstract The propagation success of bougainvillea through hardwood stem cutting varied with rooting hormones and rooting media. This experiment was carried out to study the effect of rooting hormone and rooting media on hardwood cuttings of Bougainvillea glabra cv. Double Red during April-July, 2021. The treatments were combination of rooting hormones [Indole-3-Butyric Acid (500 mg L-1), Indole-3-Butyric Acid (1,000 mg L-1), Naphthalene Acetic Acid (1,500 mg L-1), Naphthalene Acetic Acid (3,000 mg L-1), Rootex C] and different rooting media (soil and farmyard manure, sand and farmyard manure, sand and cocopeat) in 1:1 ratio. Cuttings without rooting hormones served as control. We observed earliest sprouting (10.33 days) of cuttings treated with IBA (500 mg L-1) and planted in sand and cocopeat. The highest sprouting percent (100%) and length of longest sprout (49 cm) were recorded when cuttings were treated with Rootex C and planted in sand and cocopeat. The highest shoot fresh weight (10.04 g), shoot dry weight (2.09 g), length of root (13.75 cm), number of roots (34.17), root fresh weight (2.33 g) and root dry weight (0.24 g) was observed in cuttings treated with IBA (1000 mg L-1) and planted in sand and cocopeat. The effect of rooting hormone and rooting media on the diameter of sprouts, rooting percentage, and transplanting success percentage was non-significant. Considering economically important parameters (sprouting percentage and length of longest sprout), this study revealed that sand and cocopeat with Rootex C was the best combination for the propagation of bougainvillea.

Abstract It is challenging to plant lavender outside of suitable conditions. This economically important plant requires optimal conditions to germinate and produce a high yield. To increase the quality of this plant, tissue culture is utilized. The most problematic aspect of lavender micropropagation is that cytokinin (CK) causes hyperhydricity (HH) during the shooting process. Consequently, this study was conducted to resolve HH in micropropagated lavender plantlets. Different concentrations of silver nanoparticles (AgNPs) were applied in conjunction with 1.0 mg L-1 6-benzylaminopurine (BA). Then, the performance of HH, growth and development, as well as total phenolic (TPC) and total flavonoid (TFC) content, were evaluated. The application of 20 mg L-1 of AgNPs was found to be the optimal method for halting HH. Although shoot proliferation was lower than in BA-supplemented media-grown plants, adding this concentration of AgNPs improved shoot and root quality. An increase in secondary metabolites and antioxidant activity may have caused the remedy of HH.

Abstract The characterization of flowering phenophases and morphoagronomic knowledge is important for crop management and harvest programming. This study aimed to evaluate the duration of reproductive phenophases and conduct morpho-agronomic characterization of gladiolus cultivars. Two experiments were conducted, one in a shaded environment and the other in a full sun environment. A split-plot design in randomized blocks was used, which consisted of the planting system with single rows and twin rows in the plots and the cultivars (White Goddess, Traderhorn, Peter Pears, and Gold Field) in the subplots. The reproductive phenophases, plant development and productivity of each cultivar were evaluated. The flowering cycle lasted from 58 to 65 days when the cultivars were grown in the shaded environment, while the duration of this cycle ranged from 78 to 87 days in the full sun environment. The yield of the Gold Field cultivar was significantly higher when grown in twin rows compared to single-row planting. A shaded environment and twin-row planting are the recommended conditions for the cultivation of gladiolus in the state of Mato Grosso since they promote better stem development and early flowering of the cultivars. The Peter Pears and Gold Field cultivars are recommended for cultivation in the region due to their greater production of marketable stems.

Abstract The “Jardim de Sequeiro” (rainfed garden) is an innovative technique of naturalistic and seasonal rainfed gardening developed by Prof. Julio Pastore and a team of professionals and students at the University of Brasilia (UnB). The first experimental garden was planted at the Instituto Central de Ciências (ICC), an iconic brutalist building at the University of Brasília and a landmark of modern Brazilian architecture. The garden extends through the 732 meters of the mega-structure, encompassing more than 5,000 square meters of rooftop gardens planted on a thin layer of soil. The experimental garden is primarily grown from seeds, making it a dynamic space. Beginning with fast-growing species, plants bloom in succession throughout the summer and early autumn. The garden is “rainfed,” relying entirely on rainfall for water, and it withers and dries with the onset of the winter drought. As such, it can be considered a garden-installation: a temporary occupation that is redesigned and improved every year. Conceived and planned during the initial months of the COVID-19 pandemic, the garden’s first cycle occurred between December 2020 and May 2021, when the university was closed. Despite the difficulties inherent to the pandemic period, the innovative nature of the project has yielded promising results.
“Jardim de Sequeiro”(雨养花园)是一种创新的自然主义和季节性雨养园艺技术，由巴西利亚大学(UnB)的Julio Pastore教授和一个由专业人士和学生组成的团队开发。第一个实验花园种植在Ciências中央学院(ICC)，这是Brasília大学的标志性野兽派建筑，也是巴西现代建筑的地标。花园延伸到732米的巨型结构中，包括5000多平方米的屋顶花园，种植在薄薄的一层土壤上。实验花园主要由种子生长，使其成为一个动态空间。从快速生长的物种开始，植物在整个夏季和初秋连续开花。花园是“雨养”的，完全依靠降雨来补水，随着冬季干旱的到来，它会枯萎和干燥。因此，它可以被认为是一个花园装置:每年重新设计和改进的临时占用。在COVID-19大流行的最初几个月里构思和规划，花园的第一个周期发生在2020年12月至2021年5月，当时大学关闭。尽管大流行病期间存在固有的困难，但该项目的创新性质已产生了有希望的成果。

Abstract Traditionally, Torch Ginger is commercially propagated via rhizomes. Micropropagation (M) is a viable alternative that ensures the genetic and phytosanitary quality of plantlets. However, in vitro cultivation conditions can lead to morphophysiological disorders resulting in death or difficulties in the acclimatization process and establishment of seedlings/plantlets in field conditions. Thus, Arbuscular Mycorrhizal Fungi (AMF) has been used in some crops in order to mitigate the drastic effects during acclimatization and establishment of micropropagated plantlets in the field. In this sense, the objective of this study was to evaluate the implantation forms and efficacy of micropropagation and AMF inoculation on the establishment and production of Torch Ginger plants. The planting was carried in shading screens (50%) and different implantation forms were used; through rhizome (RIZ) and plantlets micropropagated with (M+AMF) and without (M-AMF) inoculation with arbuscular mycorrhizal fungi. Evaluations of growth, phenology and mycorrhizal colonization were carried out for one year. Micropropagation, independently of AMF inoculation, favoured a better development in height and number of tillers when compared to RIZ plants It is concluded that micropropagated plants of E. elatior showed earlier tiller emission, better development and initial establishment in the field. Additionally, the forms of implantation of E. elatior via rhizome and via micropropagation with or without AMF inoculation produce inflorescences with the minimum characteristics required for commercialization.

Abstract Trichopilia suavis is one of the important representatives of the genus Trichopilia, which can be used as a potted plant for the interior design. also, its beautiful inflorescences are added unusual element to bouquet compositions and actively used in the production of perfumes. This study was carried out in order to develop and improve micropropagation method for mass clonal production of T. suavis through protocorm culture. Half-strength Murashige and Skoog culture medium (½) has been modified by adding different organic components and growth regulators. The protocorms obtained from seeds germinated by asymbiotic method were used as explants. The results showed that the optimal treatment for formation of new protocorms (7.50 ± 0.7 units per protocorm) was obtained by culture on ½ MS medium with 0.5 mg L-1 of 6-Benzylaminopurine (6-BAP) and 100 mL L-1 of coconut water. At the stage of rooting, the highest number and length of roots (7.0 ± 0.45 units per plantlet, 2.64 ± 0.18 cm) were obtained through subsequent cultivation of plantlets on ½ MS medium with 0.5 mg L-1 indolyl-3-butyric acid (IBA), 1.0 g L-1 charcoal with the addition of 50 g L-1 of banana puree. The obtained seedlings were successfully adapted in a substrate consisting of bark, perlite and peat in a ratio of 1:1:1.

Abstract Heliconias are tropical plants with ornamental potential. These plants are particularly used in the floriculture industry because of their exotic colors and shapes. Species characterization is important for the selection of genotypes for the ornamental plant market and subsequent application in studies of genetic improvement. The aim of this study was to estimate the genetic divergence of Heliconia densiflora and Heliconia psittacorum accessions based on quantitative morphological and molecular markers. The morphological and molecular descriptors revealed genetic variability among the accessions evaluated. The greatest genetic variability was observed among H. psittacorum accessions, whose sample number was also larger compared to H. densiflora. Morphological characterization was efficient in differentiating the two Heliconia species, especially to characteristics such as bract and inflorescence length, postharvest durability, and flower stem diameter, which contributed most to the divergence in this study. On the other hand, molecular characterization identified one H. densiflora individual that was grouped with the H. psittacorum genotypes. The results showed that ISSR markers can differentiate closely related H. densiflora and H. psittacorum individuals. The materials evaluated can contribute to the maintenance of local genetic diversity through the germplasm bank of the local breeding program of ornamental tropical plants.
