Jernang (Daemonorops draco (Willd.) Blume) is a dioecious rattan species that produces resin on female individuals. The sex of jernang can only be identified from its inflorescences morphology. Sex survey was conducted in 5 populations ofÂ jernang, 3 populations of which in the Bukit Tigapuluh National Park (BTNP), 1 population in the secondary forest in Jambi province and 1 population in the area of rubber plantation in Jambi province. Chi-Squared test on the sex ratio ofÂ jernang showed that the ratio of the male to female in their natural habitat (Bengayoan and Tebo, 2 parts of the BTNP ecosystem and the Sepintun secondary forest) was distorted from the normal ratio of 1:1, while the cultivated jernang in Nunusan population (BTNPT) and Mandiangin were not significantly different from the normal sex ratio of 1:1. Female individuals from the cultivated population in the Mandiangin (planted in 1997) has an average number of stems per clump more on individual males (27.12) than females (26.92). The result of this study indicated that the D. draco has a good reproductive strategy and thus suitable for cultivation.

Pigeon orchid is one of epiphytic wild orchids and very important species in the genus Dendrobium. Flowering phenology of this species is still unclear. The purpose of this study was to describe flowering phenology of pigeon orchid. The study was conducted in Limau Manis Padang, West Sumatera and has been done from May until October 2015. Some aspects of flowering phenology such as the phase of flowers, flowering period, rainy time and stigma receptivity were observed. The results of this researchÂ indicated that pigeon orchid flowering was induced by dicreasing of the temperature after rain. Flowers development consist of six phases from bud phase to be wilt with a span of 14 days and sometime stigma has begun receptive before the anthesis but optimal stage of stigma receptivity pigeon orchid occurs during anthesis.Key word: Phenology, pigeon orchid, stigma reseptivity.

Abstrak Penelitian tentang perkembangan aerenkim pada kangkung darat dan kangkung air telah dilakukan pada bulan Oktober 2014 sampai Februari 2015 di Laboratorium Struktur Perkembangan Tumbuhan Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Andalas. Jaringan akar diproses dengan metode parafin, kemudian dideskripsikan secara kuantitatif. Rongga aerenkim pada kangkung air terbentuk pada minggu ke tiga dengan jumlah dua rongga sel sedangkan pada kangung darat terbentuk pada minggu ke empat. Proses pembentukan aerenkim terjadi melalui proses pelisisan sel korteks.Abstract Research of aerenchyma development on terrestrial kale Ipomea reptans poir and water kale Ipomoea aquatic Forsk was conducted from October, 2014 until February, 2015 at Laboratory of plant growth structure, the Faculty of Math and Science, Department of Biology, Andalas University. Kales were analyzed by using paraffin method then described by quantitive data. Results showed: (i) aerenchyma cavities were formed in the 1st week, (ii) aquatic Forsks with two cell cavities were formed in the 3rd week, (iii) terrestrial kales were formed in the 4th week. The formation process of aerenchyma occurred through lysis process of cortical cell.

The Study about Analysis of Nepenthes Hybrids in Taratak Hill, Pesisir Selatan Sumatera Barat by RAPD Technique had been conducted from May until November 2011. The study was done to prove natural hybrids of Nepenthes by RAPD technique and to determine the relationship of natural hybrids of Nepenthes with both parental. The research method is survey and observation. Isolation of DNA carried by CTAB method with modifications and amplification carried out by PCR. Hybrids and parental relationship was obtained from Jaccard similarity coefficient and displayed in a Dendogram (family tree) and PCO analysis to look genetic variation was processed with the program PAST 2.10. Proof of the natural hybrid N. ampullaria × N. mirabilis can be done by the RAPD technique using the primers OPA 15, OPK 16, OPK 19 and OPP 15. Natural hybrids between N. ampullaria × N. gracilis using the primers OPA 15, OPK 19 and OPP 15. The eighth of natural hybrids N. ampullaria × N. mirabilis were closer to N. mirabilis, while both natural hybrids N. ampullaria × N. gracilis closer to the N. Ampullaria.

PERBANDINGAN KOMPONEN MINYAK ATSIRI ANTARA DAUN MUDA DAN DAUN DEWASA PADA HYPTIS SUAVEOLENS (L.)POIT Chatri, Moralita; Mansyurdin, Mansyurdin; Bakhtiar, Amri; Adnadi, Perri

Hyptis suaveolens (L.) Poit is one of the species Lamiaceae family (Labiatae), is an aromatic plant and can produce essential oils. Essential oils of these plants can be utilized as antimicrobials. The chemical components contained in the essential oils in the same plant may vary as they are influenced by several factors, including the growth stage. Essential oils can be obtained by hydrodestilation and their components are analyzed using gas chromatography-mass spectrometry (GC-MS). The essential oil components are then compared between those found in young leaves and adult leaves. The results of analysis and identification showed that in young leaves there are 50 components while in adult leaves there are only 37 components. The main components of young leaves were ?-caryophyllene (34.65%), germacrene-D (10.32%), ?-bergamotene (6.56%), ?-copaene (5.94%) and rimuene (6.46%), Are ?-caryophyllene (23.53%), germacrene-D (9.52%), ?-elemente (6.53%) and rimuene (13.19%). The components of ?-bergamotene and ?-copaene are not found in adult leaves.

The pollination study on Daemonorops draco (Wildd.) Blume has been conducted based on structure of inflorescence, pollen and ovul ration, and apomixis. The result of study present that inflorescence structure of D. draco was androdioecious. Based on the color of the inflorescence on anther and crown indicated that D. draco pollination systems supported by insects (Trigona spp.). Pollination systems of D. draco based on ratio pollen ovule is xenogami (outcrossing). Apomixis process proved that fruit of D. draco can be formed without convergence of gametes/males and females which have the character of apomixis.

Anaphalis javanica and A. longifolia, were collected during the expeditionto Mt. Merapi, Singgalang, Tandikat, and Talang (West Sumatra). Beside two of these species, several individuals of Anaphalis that differs in several characters from the two others species were also found. Based on it, morphometric study and biology reproduction analysis were carried out to clarify their taxonomic classification. Fifty three individuals of Anaphalis were collected and twenty four characters had been observed and measured to define species and morphology variation. Data analysis revealed that the alien species were defined as a natural hybrid of A. javanica and A. longifolia. There was no significant difference that number and morphology of pollens among populations as well as those two species studied. Based on the P/O ratio analysis indicated that breeding system of A. javanica and A. longifolia were facultative xenogamy. The same ornamentation (echinate) in both of two species suggested that the natural hybridization between two species was possible.

Saurauia Willd. is a genus of perennial plant or bush which usually found in highland forest or as rheophyte in rocky areas along the river bed. There are 12 species of this genus found in West Sumatera. The purpose of this research is to analyze the grouping of Saurauia species based on morphometric analysis and determine the pollination system based on pollen-ovule (P/O) ratio. The research has been conducted since September 2014 until December 2015 by using the self-collected specimen and Herbarium ANDA specimen. Morphometric analysis was applied to all 12 species which consist of 21 morphological characters and pollen–ovule (P/O) ratio was applied to 10 species. The results of this research are: generally the euclidian distance is ranged 7.35-14.73. The shortest one is S. cerea and S. laxa which d point is 7.35 and the longest one is S. cerea and Saurauia sp. which the d point is 14.73. Saurauia sp. is closely related with S. leprosa and S. bracteosa which are belonged to same sub cluster and having the same character which are glabrous leaf surface, acuminate apex and 5 similar sepals. Pollen-ovule (P/O) ratio determined the pollination system of Saurauia is xenogami.
