“…Some epiphyte ferns like dry and wet water such as stag horn ferns [17]. In addition, when the root mass of the bird's nest fern becomes dry, it can absorb a lot of water during the rainy season [28]. The root mass of this fern can be used as a fern planting material [29].…”

The increasing demands of gardeners have made peat moss a popular option as a planting material. However, the price of peat moss has increased recently. Therefore, alternative substances for use as a planting material need to be studied. The root of the bird's nest fern offers a cheaper, easier to produce and more readily available source for a planting material than peat moss. The objective of this research was to increase root mass growth by using drip irrigation. With an experimental design using CRD, two-year old bird's nest ferns with root mass sizes of 5 inches were watered by means of a drip irrigation method at rates of 200, 400, 600, 800 and 1,000 ml every 3 days. The data measured were root mass height, root mass diameter, leaf length, leaf width and canopy width. The data were analyzed by ANOVA and the differences between the means of treatment were compared by DMRT. The research found that the ferns which received water at a rate of 800 ml produced a root mass height of 11.06 cm and a root mass diameter of 11.93 cm. They were significantly different (p<0.05). The ferns which received water at a rate of 200 ml produced a leaf length of 29.52cm and a leaf width of 9.55 cm. The amount of water causes fern growth to significantly different (p<0.01). The 800 ml rate of drip irrigation also produced the largest canopy width of 48.12 cm.

“…A. nidus , the bird's nest fern is present in tropical rainforests on tree trunks or rocks, whereas A. komarovii is a terrestrial species that thrives in temperature regions. A. nidus is considered to be more sensitive to climate fluctuations and could endure severe drought stress, nutrient shortage, and intense sunlight [5, 36, 37]. Several epiphytic ferns exhibit features typical of CAM photosynthesis—an adaptative mechanism to dry habitats [6–8].…”

Epiphytic ferns have been found to flourish after angiosperms dominated forest communities, and they play important roles in rainforest canopies. How do epiphytic ferns adapt to tropical rainforest canopy habitats? At present, we know little about the molecular mechanism underlying this adaptation. Asplenium nidus is a well-known epiphytic fern that is closely related to the terrestrial species Asplenium komarovii. Here, RNA-seq and comparative transcriptomic analyses were performed to explore the underlying basis of the adaptation of A. nidus to extreme environments. A total of 44.04 and 44.57 Mb clean reads were obtained from A. nidus and A. komarovii, respectively, and they were assembled into 89,741 and 77,912 unigenes. Functional annotation showed that 52,305 (58.28% of the total genes for A. nidus) and 45,938 (58.96% of the total genes for A. komarovii) unigenes were annotated in public databases. Genes involved in stress responses and photosynthesis were found to have undergone positive selection in A. nidus. Compared to A. komarovii, transcription factors related to stress response, leaf development, and root development were found to be considerably expanded in A. nidus, especially in the ANR1 subclade of MADS-box family genes which played roles in lateral root development. This study improves our understanding of the adaptation of A. nidus to epiphytic habitats by forming unique strategies.

Abstract. The use of Erica manipuliflora, a decorative native ornamental species, is limited in landscaping due to insufficient plantlet production in nurseries. The aim of study was to determine the most effective and practical adventitious rooting (AR) protocol for successful vegetative production of E. manipuliflora. Two experiments (Expt.) were established in November and June to reveal the effects of different substances [perlit and perlit:sphagnum peat (1:1 v/v) in Expt.I and peat, peat:sand (1:1), cocopeat:sand (5:1) and perlite in Expt.II] and exogenous auxins including liquid (in Expt.I) and powdered (in Expt.II) formulations of IBA, NAA or combination of both. The results indicated E. manipuliflora cuttings taken in June and cultured in cocopeat:sand (5:1) mixture without any auxin treatment presented the highest survival (84%) and rooting (76%) performance. In addition, exogenous auxin usage is not essential for AR of E. manipuliflora cuttings. It can be used for the cuttings inserted in cocopeat-free media. But it exhibited reducing effect on rooting in cocopeat-based medium. The use of mycorrhizal inoculation and also minicuttings in eco friendly cocopeat-based media in future studies might increase the efficiency of E. manipuliflora AR protocol.
