Abstract:

Epiphytic ferns can be found in host trees from the Angiosperm and Gymnosperm groups. Epiphytic ferns in Angiosperm plants host have been widely studied, but there is little known for Gymnosperm plants host. The aim of this study was to identify the species of epiphytic ferns in the Gymnosperm plants host at Cibodas Botanical Garden and to analyze the diversity of epiphytic ferns based on microclimate conditions and the surface texture of Gymnosperms plants host. Epiphytic ferns diversity data was obtained using purposive random sampling method. Factors that influence the occupancy of ferns are analyzed using Principal Component Analysis. Epiphytic ferns in Gymnosperm host at Cibodas Botanical Garden were identified as 18 species including 7 family. The most dominant species of epiphytic fern is Davallia denticulata (59.45%). Diversity of epiphytic fern on Gymnosperm at Cibodas Botanical Garden is moderate (H’ = 1.81).

Abstract:

Kekeringan merupakan salah satu masalah serius yang sering muncul ketika musim kemarau tiba dan berkepanjangan. Dari aspek hidrometeorologi kekeringan timbul dan disebabkan oleh berkurangnya curah hujan selama periode tertentu. Tujuan dari penelitian ini adalah untuk mengetahui jenis pohon dengan transpirasi paling besar berdasarkan karakteristik daun dan hasil total transpirasi. Hasil penelitian ini menunjukkan pohon gymnospermae yang daun paling lebar yaitu daun pohon melinjo 1 yaitu lebar 5,3 cm dan jenis pohon angiospermae yang daunnya paling lebar yaitu daun pohon ketapang 2 yaitu lebar 18,4 cm. Jenis pohon gymnospermae yang daun paling tebal yaitu daun pohon cemara norflok 1 dengan tebal daunya yaitu 0,049 mm, sedangkan jenis angiospermae pohon dengan daun paling tebal yaitu daun pohon ketapang 3 dengan tebal daunnya itu 0,015 mm. Jumlah total daun paling banyak yaitu jenis glodokan sebesar 7809. Pada jenis pohon gymnospermae rata-rata jumlah uap air yang dihasilkan paling banyak adalah pohon Melinjo dengan jumlah rata-rata 1.428,07 ml. Sedangkan pada jenis pohon angiospermae, pohon yang paling besar menghasilkan uap air yaitu Ketapang dengan nilai rata-rata 9.607,6 ml. Dari hasil pengamatan, peneliti menyimpulkan jenis pohon angiospermae yang paling banyak menghasilkan uap air yaitu jenis pohon Ketapang, karena dilihat dari panjang daun, lebar daun dan tipisnya daun sehingga pohon ketapang yang paling banyak menghasilkan uap air.

Abstract:

En este artículo se incluye la primera parte del atlas de flora alóctona de la Comunidad de Madrid, que incluye los taxones de helechos y gimnospermas. Únicamente se han considerado taxones que crecen fuera de zonas urbanas, parques y jardines, tanto introducidos como naturalizados. En total se han analizado 49 taxones, 2 de helechos y 47 de gimnospermas (33 Pinaceae y 14 Cupressaceae). De ellos, se han considerado 34 taxones (1 Salviniaceae, 22 Pinaceae, 11 Cupressaceae) incluyendo mapas de distribución, mientras que en otros 15 su presencia es dudosa en la actualidad o están únicamente localizadas en zonas urbanas. Dominan las especies de Pinaceae como resultado de las plantaciones forestales realizadas. Buena parte de las especies consideradas tienen capacidad para naturalizarse (se tiene constancia en 19 de ellas), pero por lo general su capacidad de expansión es limitada, no siendo invasoras; únicamente Azolla filiculoides Lam. tiene un comportamiento invasor, aunque su distribución en Madrid parece estable.

Abstract:

Cunninghamia lanceolata (C. lanceolata) belongs to Gymnospermae, which are fast-growing and have desirable wood properties. However, C. lanceolata’s stress resistance is little understood. To unravel the physiological and molecular regulation mechanisms under environmental stresses in the typical gymnosperm species of C. lanceolata, three-year-old plants were exposed to simulated drought stress (polyethylene glycol 8000), salicylic acid, and cold treatment at 4 °C for 8 h, 32 h, and 56 h, respectively. Regarding the physiological traits, we observed a decreased protein content and increased peroxidase upon salicylic acid and polyethylene glycol treatment. Superoxide dismutase activity either decreased or increased at first and then returned to normal under the stresses. Regarding the molecular regulation, we used both nanopore direct RNA sequencing and short-read sequencing to reveal a total of 5646 differentially expressed genes in response to different stresses, of which most had functions in lignin catabolism, pectin catabolism, and xylan metabolism, indicating that the development of stem-differentiating xylem was affected upon stress treatment. Finally, we identified a total of 51 AP2/ERF, 29 NAC, and 37 WRKY transcript factors in C. lanceolata. The expression of most of the NAC TFs increased under cold stress, and the expression of most of the WRKY TFs increased under cold and SA stress. These results revealed the transcriptomics responses in C. lanceolata to short-term stresses under this study’s experimental conditions and provide preliminary clues about stem-differentiating xylem changes associated with different stresses.

Abstract:

Ethnomedicinal information is one of the powerful criteria for new drugs discoveries therefore; present investigation was carried out to evaluate the ethnomedicinal and antibacterial potential of traditional Kumaun Himalayan gymnosperms. Besides, an antibacterial value index and relative antibacterial activity of studied plants have been established. Forty four plant leaves extracts in different organic solvents (methanol, ethanol, chloroform and hexane) of 11 gymnosperms (Araucaria cunninghamii, Biota orientalis, Cedrus deodara, Cephalotaxus griffithi, Cryptomeria japonica Cupressus torulosa, Ginkgo biloba, Juniperus communis, Picea smithiana, Pinus wallichiana and Taxus baccata) occurring in Kumaun Himalaya were screened for their antimicrobial activity against five pathogenic bacteria using disc diffusion method. The antibacterial activity of studied gymnospermic plant extracts against a panel of bacteria was found effective at 1000 µg/ml. The MIC and MBC values of each extract (where ZOI ≥ 15 mm) were also determined. The methanol extract of screened gymnosperms were found the most effective against all the bacteria (54% to 81%), followed by ethanol extract (45-72%), hexane extract (18-27%), while in chloroform extract it ranged 9-27% only. The extracts of G. biloba exhibited superior Relative Antibacterial Activity (RAA, 20%), followed by A. cunninghamii and P. wallichiana (12% RAA, each). The lowest RAA value was observed for C. torulosa (1%). All data were also analyzed for determination of an Antibacterial Value Index (ABVI) for each studied species of gymnosperm. G. biloba had maximum ABVI i.e. 90 % followed by A. cunninghamii and P. wallichiana (ABVI, 55% each). C. torulosa showed the least ABVI and RAA i.e. 5% and 11%, respectively. The present work fully highlighted the utility of traditionally known 11 gymnosperms of Kumaun Himalaya for their antibacterial activities against pathogenic bacteria.

Diagnostic parameters, such as heterocellular medulla composed of parenchymatous and sclerenchymatous cells, primary xylem endarch, secondary xylem with dominant uniseriate bordered pits, spiral thickenings in the radial walls of tracheids, medullar rays homocellular, absence of resiniferous canals and axial parenchyma, indicate its relationship with the family Taxaceae, reporting on the first recognition of this group in the Triassic on Southern Pangea. This evidence supports the hypothesis that the Taxaceae at the Mesozoic were not con?ned to the Northern Hemisphere.

Abstract:

Tasmania is the south-eastern island state of Australia. It is geographically isolated and is recognised for both its rich diversity of plant species and high degree of endemism. Although 530 endemic Tasmanian vascular plant species are known, natural products have only been isolated from 27 of these species (~5.1 %), representing 3 classes (Dicotyledonae, Monocotyledonae, and Gymnospermae), 12 families, and 14 genera. Terpenoids, flavonoids, and alkaloids are the major classes of compound that have been isolated from these species. This report provides the first review of the natural products isolated from endemic Tasmanian plant species and covers ~70 years of research in this area.

Abstract:

Pondok Pesantren Nuris Jember memiliki julukan sebagai Green Campus karena keanekaragaman tumbuhan hijaunya yang terdapat di kawasan pondok pesantren ini. Mayoritas tumbuhannya adalah jenis tumbuhan berbiji (spermatophyta). Tujuan penelitian ini adalah untuk mengetahui jenis-jenis tumbuhan yang ada di Pondok Pesantren Nuris Jember. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif. Sumber data penelitian ini adalah tumbuhan spermatophyta di Yayasan Pondok Pesantren Nuris Jember. Hasil penelitian menunjukkan bahwa terdapat 43 jenis tumbuhan dengan rincian satu spesies Gymnospermae dan 42 spesies dari Angiospermae yang terdiri dari 13 spesies tumbuhan biji keping satu (monocotyledoneae) dan 29 spesies tumbuhan biji keping dua (dicotyledoneae). Sehingga keanekaragaman tumbuhan di kawasan Pondok Pesantren Nuris didominasi dengan tumbuhan Angiospermae kelas dicotyledoneae.

Abstract:

The anatomy of growth rings in Agathis vitiensls (Araucariaceae; Gymnospermae) in Fiji is described, and also the eccentricities in ring formation produced by variations in cambial activity. Latewood is formed during the dry season, and earlywood coincides with leaf and shoot growth during the hotter wet season. Radiocarbon dating of five trees indicates an approximately annual ring frequency. A relationship between trunk diameter and age is defined, with 95% confidence limits: age (years) ͭ6 25 + 3.7 (diam. of trunk, cm), ± 32%. The size-class frequency distribution of trunk diameters is consistent with a constant mortality amongst canopy trees. A cyclone caused seed cones to disintegrate, dispersing the seeds and establishing a transient seedling population.
