Abstract

Mahoni daun lebar (Swietenia macrophylla King.) merupakan jenis eksotik dari Amerika Latin yang telah ditanam di Indonesia sejak tahun 1870. Jenis ini merupakan pemasok kayu pertukangan yang cukup penting di Indonesia. Tujuan penelitian adalah mengetahui pengaruh sumber benih dan famili terhadap keragaman pertumbuhan bibit S. macrophylla untuk mendukung kegiatan pemuliaan. Rancangan percobaan yang digunakan Rancangan Acak Lengkap yang terdiri dari dua faktor, yaitu sumber benih (Banjar-Jabar, Samigaluh ? Kulonprogo, Bondowoso-Jatim dan Lombok-NTB) dan famili (35 famili). Hasil analisis menunjukkan bahwa sumber benih berpengaruh nyata terhadap pertumbuhan tinggi dan diameter batang, sedangkan famili berpengaruh nyata terhadap pertumbuhan tinggi, diameter batang dan jumlah daun pada umur 7 bulan. Pertumbuhan bibit dengan tinggi terbaik (55,8 cm) berasal dari sumber benih Banjar dan pertumbuhan bibit dengan diameter batang terbaik berasal dari sumber benih Banjar dan Lombok masing-masing sebesar 0,62 cm dan 0,61 cm.Effect of Seed Source and Family on The Growth of (Swietenia macrophylla King.) Seedling at Seven Months Old.AbstractSwietenia macrophylla King. is an exotic species from Latin America which have been planted in Indonesia since 1870. This species is a good wood source for construction timber which is quite important in Indonesia. This study was conducted to determine the effect of seed source and family on S. macrophylla seedling growth which may be useful for supporting breeding program of this species. The seeds were collected from four seed sources: Banjar - West Java, Samigaluh - Kulonprogro, Bondowoso - East Java and Lombok ? West Nusa Tenggara. Every seed source consisting of 10 families, except Bondowoso which had 5 families. The study was arranged in a randomized complete design, five seedlings per plot and repeated 5 times for each family. At 7 months old the seed source had significantly influence on height and stem diameter, while the family significantly influence height, stem diameter and the number of leaf. Banjar seed source had the best height growth (55.8 cm), while Banjar and Lombok seed sources had the best stem diameter, respectively 0.62 cm and 0.61 cm.

Abstract

The development of teak clones (Tectona grandis L.f.) is currently being done by industry and farmers to increase productivity. The use of superior teak clones will determine the success of planting; therefore, the superior clones need to be developed. Knowledge of variations in growth and fruiting in the seed orchard of teak clones is important to determine the reproductive capacity of a plant. Therefore, study on variations in the growth and fruiting of teak clones was undertaken. The study was conducted at 11 years old of teak clones, located in Alas Ketu Wonogiri, Central Java. The teak plants measured were planted with a spacing of 2 x 6 m, using a randomized block design, with 100 clones; 3 ramet per clone and consists of 5 blocks as replications. The clones originated from Gunung Kidul, Madiun, Cepu, Wonogiri, Randublatung, Rembang, Muna, Matakidi, Kendari, Buton, and Thailand. All individual tress in the plots were examine for collecting data. Parameters were measured including height of trees, diameter breast height, flower and fruit production. The results showed that height and diameter growth varied significantly between clones, as well as between replications; while flower and fruit production did not show significant differences between clones and between replications. When the clones grouped in height class and diameter class, it showed that the production of flowers and fruits of teak clones were differs significantly. Moreover, the reproductive success of this teak clone seed orchard was very low at 2.15%, suggested due to very little rainfall during the flowering season which causes many flowers to fall out.

Abstract

Two Falcataria moluccana (sengon) progeny trials, incorporating 100 different families from 12 provenances growing on two highly gall rust (Uromycladium falcatarium) prone sites were used to estimate genetic parameters and potentially identify rust-resistant material. The analysis was performed to assess provenance- and family-level survival, rust incidence, and growth at the two progeny trials. Height, diameter, survival, and rust incidence was measured at two progeny trials at 18 months-of-age located at Jember and Lumajang, East Java. Rust incidence at the two trial sites was severe, with only 39% overall survival (35% and 43% at Jember and Lumajang, respectively). The analysis revealed significant genetic variation at the provenance level for survival, rust incidence, and growth. No statistically meaningful narrow-sense heritability of these traits was indicated, though this is probably reflective of the inadequate within-family replication and effects associated with uneven stocking resulting from rust-induced mortality. The significant genotype-by-environment (provenance-by-site) interaction was also indicated, though the performance of some of the best- and worst-performing provenances was relatively stable, allowing recommendations of suitable provenances for further testing on rust-prone sites.

Abstract

Flowering intensity, insects visiting flowers and pollinators of S. album were determined in a study conducted in an ex-situ conservation plot, Watusipat, Gunung Kidul, Yogyakarta. Observations were undertaken during flowering season in 2009 and 2010, with an objective to determine the patterns of flowering and flower visiting insects of S. album in this population. In this study site, S. album typically flowers twice a year and reaches a peak on June and November. Flowers are visited by various insects, major in honey bees and ants. Santalum album is predominantly cross pollinated by insects however, low number of fruit set found in an open pollination. Variation of flowering intensity and the degree of self-incompatibility may influence the low number of fruit production in this species.

Abstract

Stigma  receptivity based on seed set and pollen  tubes growth  following controlled pollination of flowers  of different  ages was examined  in Melaleuca alternifolia. The stigma secretion during 10 days after anthesis and pollen viability under three different temperatures and five storage times were also observed. These series of research were undertaken because successful controlled pollination of M. alternifolia depends on the application of viable pollen to the receptive compatible  stigma. The objective of this research was therefore to determine the stigma receptivity and pollen viability of M. alternifolia. Results showed that the stigma receptivity began to develop  on day  one and finished  on day  seven after anthesis,  peak receptivity occurred from day three to day six. The stigma receptivity also coincides with the appearance of secretion in the stigma, occurring  from day three to day seven after anthesis. Therefore,  the time for pollination of M. alternifolia appeared to extend for  approximately 7 days after anthesis. Data for M. alternifolia showed that regardless of storage temperature, pollen  was still  viable  after 26 weeks  of storage;  results also demonstrated  that the lowest temperature  (-18oC) was the best regime for long term storage.

Abstract

Family variation of capsule production and the seed viability in the Paliyan full-sib trial of Melaleuca cajuputi subsp. cajuputi, at Gunungkidul, Yogyakarta, were observed. The full-sib trial was designed as Incomplete Block Design, consisting of 39 families; six individual as tree plot and replicated in eight blocks. Height and diameter at breast height were assessed to identify the correlation between capsule category and growth performance. The capsule production was assessed visually to one of the capsule categories: “0” for none; “1” for light; “2” for medium and “3” for heavy. Results showed that each family of M. cajuputi sub sp. cajuputi equally contributed  to the seed production.   Progeny analysis showed that the seed productions were not strongly under genetic control (h2i) = 0.12. This study also found positive correlation between the flowering strength (the flower production levels) and the number of capsule (R2=0.279). However, there were no significant differences between the flowering levels and the viability of M. cajuputi sub sp. cajuputi. Mean seed viability was 31%,  there were no significantly differences of capsules production between trees having high flowering intensity and low flowering intensity. Low seed viability was assumed due to the unsynchronicity of flowering, leading to the low levels of outcrossing rate. Therefore, selection of families with synchronicity of flowering was recommended to establish a seed orchard.

Abstract

As a part of tree improvement project of sengon (Falcataria moluccana L. Nielsen) several progeny test  were established in December 2011. One of those progeny test  was established in Bondowoso, East Java.  Row Column Desgin (Incomplete Block Design) was used as experimental design involving 70 families (9 Papua provenance and 1 provenance Solomon), 4 replications (blocks), 4 trees per plot and a spacing of 3 x 2 m. Observations were made at the age of 6 and 12 months, including recorded the percent of survival plants, height, diameter and the gall rust incidence. Results showed that in general, the early growth of individual plant in this plot demonstrated a fairly good performance with the survival rate of 98.5% (6 months old), and 96.9% (1 year old). The early growth of sengon varied significantly between provenances. The best growth demonstrated by provenances from Meagama, Holima and Hobikosi. Early estimation of individual heritability of plant height categorised in low (h2i= 0.07 to 0.11, h2f= 0.16 to 0.21), whereas individual heritability of diameter were catagorised in medium (h2i= 0, 08 to 0.27, h2f= 0.15 to 0.43). Moreover, the positive value of the genetic correlation revealed between height and diameter (0.88 and 0.85). Several individual trees originated from Holima, Meagama and Elagaima exhibited 0% of gall rust disease incidence.

Abstract

Informasi tentang morfologi pembungaan sebagai langkah awal mengetahui sistem reproduksi untuk menentukan langkah konservasi sangat diperlukan. Tujuan penelitian ini adalah untuk mengetahui morfologi pembungaan dan sistem reproduksi merbau. Pengamatan intensitas pembungaan dan pembuahan dilakukan setiap 1 minggu sekali selama 6 bulan mulai bulan Mei hingga November2013. Pengamatan perkembangan organ generatif dilakukan setiap hari untuk mengetahui tahapan perkembangan bunga dan buah.Hasil penelitian menunjukkan bahwa pembungaan tersusun dalam malai, hermaprodit dengan kemasakan bunga yang tidak serempak. Organ reproduksi bertipe heterostyly dan bersifat protandry. Tidak terdapat buah yang terbentuk dari hasil percobaan dengan penyebukan sendiri (self-pollination). Hal ini memperkuat dugaan tentang sistem polinasi silang (xenogamy). Pembungaan terjadi dua kali setahun dengan puncak pembungaan Juni dan November, diikuti dengan kemasakan buah pada 3 bulan berikutnya. Terdapat berbagai macam serangga yang mengunjungi bunga merbau, namun sangat sedikit serangga penyerbuk yang ditemukan pada populasi uji. Rendahnya keberhasilan reproduksi selain dikarenakan sedikitnya jumlah bunga dan serangga pengunjung, juga karena adanya ketidakcocokan berkawin sendiri, sehingga upaya melakukan perkawinan silang atau memperbanyak serangga penyerbuk perlu dilakukan.
