Abstract

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 of  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 of  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.

Abstract

Colletotrichum gloeosporoides adalah salah satu jamur yang menyebabkan penyakit antraknosa pada cabai. Jamur patogen ini umumnya dikendalikan dengan menggunakan fungisida sintetis. Fungisida sintetis ini sering meninggalkan residu dalam tanah, sumber daya air dan  tanaman yang mempengaruhi kesehatan  manusia  serta  polusi  terhadap  lingkungan. Salah satu upaya yang aman untuk pengendaliannya adalah dengan memanfaatkan bahan alam yang berasal dari tumbuhan seperti Hyptis suaveolens (L.) Poit, karena tumbuhan ini mengandung minyak atsiri yang bersifat antimikroba. Tujuan penelitian ini adalah untuk menguji efektifitas minyak atsiri daun H. suaveolens (L.) Poit dalam menghambat pertumbuhan C. gloeosporoides. Penelitian ini dilakukan dari bulan Juli sampai September 2013 di Laboratorium Mikrobiologi, Universitas Negeri Padang dengan menggunakan Rancangan Acak Lengkap, delapan perlakuan dan 3 ulangan. Perlakuan adalah minyak atsiri dari daun muda H.suaveolens (L.) Poit (konsentrasi 0,5%, 1,5%, 2,5%), minyak atsiri dari daun dewasa (konsentrasi 0,5%, 1,5%, 2,5%), kontrolpositif (fungisida sintetis) dankontrolnegatif. Parameter yang diamati adalah diameter koloni dan persentase hambatan pertumbuhan jamur. Hasil penelitian menunjukkan bahwa perlakuan minyak atsiri H. suaveolens (L.) Poit dengan semua konsentrasi, baik pada daun muda maupun daun dewasa dapat menghambat pertumbuhan jamur C. gloeosporoides. Kata kunci: Antraknosa, Colletotrichum gloeosporoides, Hyptis suaveolens(L.) Poit

Abstract

The research on estimation ploidy and genetic relationships between sample collections from Solok Balitbu Tropic has been studied from Mei 2012 until November 2013. This study was done on experimental garden in Solok Balitbu Tropic and Genetic and Sitology Laboratory, Faculty of Math and Natural Science Andalas University. The aims of this study were to reveal the rate of ploidy on some bananas accession by using Stover and Simmonds (1987) scoring system and to relieve the rate of ploidy on some bananas accession based on quantity of chromosomes. The result revealed that the rate ploidy from 20 bananas accession the presence of 8 accessions of banana AA / AAA genome, AAB genome 8 accessions of banana and 4 banana accessions AB genome. Genetic relationship from dendrogram analysis showed that there were four groups bananas accession. Groups I, III, and IV were closely related toM. Acuminata, while group II related to M. balbisiana Key words : ploidy on some bananas accession genetic relationships

Abstract

The shoot of “rajasereh” banana was treated by 0,2% and 0,5% of ethyl methane sulfonate (EMS), for 2 and 4 hoursthourgh in vitro. The results showed that treatment of EMS mutagen would be changed morphologycal characterseither in planlet. In planlet stage was obtained four morphololgycal variations. One of the variant have characterizedthe colour yellowish; the leaves and stem are yellowish: the leaves were small and spiral. The value of coefficientof variant for morfphologycal characters of planlet “raja sereh” banana increased compare to the control. Theextreme value of coefficient of variant in planlet stage was found the times shoots is 84,31%, while control that is8,24%. EMS mutagen could caused several planlets shorter, total of leaves could of shoot are mostly

Abstract

Penelitian mengenai Tingkat Keberhasilan Polinasi pada Averrhoa bilimbi L. (Belimbing Wuluh) Tipe Distili telah dilakukan pada Februari sampai April 2008 di lingkungan Universitas Andalas Padang dan Laboratorium Struktur Perkembangan Tumbuhan Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Andalas, Padang. Penelitian ini dilakukan dengan metode polinasi buatan (hand pollination) untuk perlakuan polinasi sendiri dan polinasi silang, teknik emaskulasi untuk pengujian partenokarpi. Viabilitas polen dan ukuran polen antara filamen panjang dengan filamen pendek diamati secara deskriptif. Tujuan penelitian adalah mengetahui tingkat keberhasilan polinasi sendiri, polinasi silang dan sifat partenokarpi, membandingkan viabilitas polen dan ukuran polen antara filamen panjang dan filamen pendek. Hasil penelitian menunjukkan bahwa sistem polinasi pada A. bilimbi cendrung terjadi secara silang dengan keberhasilan pembentukan buah 63,30% - 76,70%, sedangkan polinasi sendiri memiliki tingkat keberhasilan 33,33% - 60% dan tidak didapatkan sifat partenokarpi. Rata-rata viabilitas polen dari filamen panjang tidak berbeda signifikan dibandingkan dengan filamen pendek, sedangkan rata-rata ukuran polen dari filamen panjang lebih besar dibandingkan dengan filamen pendek.

Abstract

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 research  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.

Abstract

The study of root aerenchyma development of wetland paddy cv."anak daro" and upland paddy cv. "merah" at nursery stageby flooding treatment was conducted from January to April 2013 in green house and Laboratory of Plant Development and Structure, Biology Departement, Andalas University, Padang. The objective of this study was to observe the aerechyma development in the root cortex and its zone along root. The root of paddy as materials were prepared by the paraffin method. The result showed that aerenchyma was developed from cortical cells of proximal root either in wetland or upland paddy in two days after seedling. At 8 days after seedling, wetland paddy with flooding treatment formed 27-29 aerenchymatous cavities compared to 27-28 cavities of their control. Upland paddy with flooding treatment formed 28-30 aerenchymatous cavities and did not form any cavity on their control.. The aerenchyma of both paddies developed completely between outer and inner cortex in 14 days after seedling. The aerenchymatous zone was developed completely from proximal up to distal root at 21 days after seedling.Keywords: wetland paddy, upland paddy, flooding, aerenchyma development, root

Abstract

The study of comparative characters of starch grain and crystal morphologically had been done among five species of taro from January until April 2013 in Plant Structure and Development Laboratory, Department of Biology, Faculty of Mathematics and Natural Science, Andalas University. The corm of taro species were analyzed the character of shape and size by using fresh preparate. The result showed that X. sagittifolium and X. violaceum have circular starch grain, while C. esculenta cv. 1, C. esculenta cv. 2, C. esculenta cv. 3 have ellip starch grain. The shape of calcium oxalate crystals found is a bundle of raphide, individual raphide and druse. The all species of taro have individual raphide. C. esculenta cv. 1 and C. esculenta cv. 3 have raphides and druse crystal. Keywords : taro, starch, crystals, Xanthosoma, Colocasia
