“…We also observed that the germination and viability percentage of both Bauhinia species were recorded higher in polythene bags under room temperature and lower viability was found in cotton bags. The results of our study are at par with that reported for Toona ciliata M. Roem (Meliaceae) [38]. The seeds stored in cotton bags resulted in the loss of seed viability due to the loss of seed moisture during storage, which further affected the longevity of the seeds.…”

In urban forestry plantations are implemented in different cities of the world for social and environmental benefits. Bauhinia retusa and Bauhinia variegata are important species and to be used as large-scale plantation programs in urban forestry which might solve or mitigate urban, social, and environmental issues such as improving the physical & mental health of residents, food and nutrition security, increasing urban biodiversity, cooling the neighboring, preventing soil erosion, flooding, and mitigating greenhouse gas emissions and air pollution. The present study was conducted with the aim of producing quality planting material for B. retusa and B. variegata in the nursery for afforestation programs. Seeds of B. retusa and B. variegata were collected from the natural habitats to assess seed germination and seedling growth. Seeds were stored in different types of containers at room temperature and later on exposed to 15, 20, and 25 °C in seed germinator. Seeds were further sown in polythene bags according to the seed size, seed coat color, seed sowing depth, the orientation of seeds, and the result of the emergence of seedlings, their growth, and biomass were estimated. A two-way analysis of variance was calculated to estimate the variation among the studied parameters. Results revealed that a constant 25 °C temperature was considered best for seed germination of both the Bauhinia species. Polybags were found the most suitable for storing the Bauhinia seeds among the storage containers. The seedling emergence and growth were maximum in yellow color and large seeds. In B. retusa, seedling emergence, and growths were the maximum in seeds sown at a horizontal position and in B. variegata at an upright position. Seedling emergence, length, and biomass were recorded the maximum when seeds of B. retusa were sown at 4 cm depth and B. variegata seeds were sown at 2 cm depth. The study recommends that the yellow color seed that has to be sown at 2 cm to 4 cm depth with upright and horizontal positions is considered best for the production of quality planting stock of both studied Bauhinia species.

“…(Jain et al, 2019). Nigrosora sphaerica that causes leaf spot on Celtis australis (Gautam, 2014) and Rhytisma acerinum that causes tar spot on Toona ciliata (Chandel & Kumar 2017) are some of the pathogenic fungi recorded for the study tree species. Fungal pathogens play crucial roles in producing diseases.…”

This paper deals with the fungal diseases of important tree species, which have enormous economic value, i.e. Melia azedarach, Celtis australis and Toona ciliata. These tree species are used for timber, fuelwood, fodder and for infrastructure development. A number of devastating fungal diseases were prevalent among the tree species in plantation forest of Myagdi district. For Isolation and identification of pathogen infected samples were cut into small pieces, washed, sterilized with 70% ethanol and transferred to Petri plates containing potato dextrose agar (PDA) media. Then, incubated at 25 ± 2ºC and after few days when fungal colonies developed observed in microscope. These fungal pathogen causing different disease were Erysiphe kusanoi (powdery mildew), Colletotrichum gloeosporioides (anthracnose), Pestalotia neglecta and Fusarium sp. (canker) and Alternaria alternata (blight). It has been concluded that to moderate the damages caused by these pathogens, it is must to identify them early in the infection process.
