Inayah, Durrotul (2020) Variasi Individual Pertumbuhan Vegetatif dan Generatif Anggrek Spesies Terestrial di Taman Anggrek Ranu Darungan TNBTS. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk menentukan profil faktor abiotik terestrial, menganalisis variasi individual pertumbuhan vegetatif dan generatif anggrek spesies terestrial dan membandingkan fenologi antar spesies congeneric di Taman Anggrek Ranu Darungan TNBTS. Faktor abiotik terestrial yang diukur meliputi suhu, intensitas cahaya, RH, BOT, pH dan kelembaban tanah di setiap zona. Pengamatan pertumbuhan organ vegetatif dan generatif dilakukan pada 31 spesies dengan jumlah individu bervariasi antar spesies secara purposive sampling pada Juli 2019-Januari 2020. Data fenologi dan faktor abiotik dianalisis secara statistik deskriptif menggunakan Microsoft Excel dan PCA untuk membandingkan fenologi antar spesies congeneric. Hasil penelitian menunjukkan variasi bulanan iklim mikro dan faktor edafis kecuali pH tanah akibat variasi musim. Bulan Juli-Oktober merupakan bulan kering, sedangkan November- Januari merupakan bulan basah. Hal ini mempengaruhi 95% fenologi pertumbuhan vegetatif dan generatif anggrek terestrial. Sebagian besar (91%) spesies anggrek menunjukkan variasi pertumbuhan tunas dan berbunga/berbuah. Selanjutnya, 50% pertumbuhan tunas diikuti aktivitas berbunga. Spesies yang berbunga hampir di sepanjang pengamatan adalah Arundina graminifolia. Seluruh spesies congeneric memiliki variasi fenologi, namun variasi pertumbuhan tunas paling sedikit. Spesies yang aktif berbunga adalah Acanthephippium javanicum, Calanthe triplicata, dan Phaius tankervilliae.
English Abstract
The aims of this research were to determine some profile of terrestrial abiotic factors, to analyze the individual variations in vegetative and generative growth of some terrestrial wild orchids, and to compare the congeneric species phenology at the Orchids Garden of Ranu Darungan, the Bromo Tengger Semeru National Park (BTSNP). Terrestrial abiotic factors measured in each zone were air temperature, light intensity, relative humidity, soil organic matter, pH and moisture. Thirty one species orchids were observed for vegetative and generative growth of some specimen by purposive sampling from July 2019 to January 2020. Abiotic factors and phenology data were analyzed using statistical descriptive method with Microsoft Excel and principle component analysis to compare the phenology between the congeneric species. Results showed monthly variations of microclimate and edaphic factors were triggered by seasonal variations except soil pH. July to October were dry months, while November to January were wet months. These variations affected the phenology of most orchids (95%). Moreover these species (90.9%) showed a variation of shoot and flowering/fruiting growth. Furthermore, 50% of shoot growth was followed by flowering activity. Among them, Arundina graminifolia was blooming throughout the observation period. All of congeneric species showed some phenological variations, however, there was a slight variation in the shoot growth. Acanthephippium javanicum, Calanthe triplicata and Phaius tankervilliae were actively blooming.
