| Abstract (English): |
Shorea is a genus of the Dipterocarpaceae family which shows high economic and ecological values. Currently, market demand for wood is still met from natural forests that are degrading due to over exploitation. The degraded forests are included in the rehabilitation program that require significant number of planting stocks, mainly from seedlings or wildlings. Correct species identification of planting stocks, particularly wildlings, is an important first step in planting activities and it is relevant with Shorea spp planting stocks due to leaf morphology traits. This study was aimed to examine the traits of leaf morphology of four Shorea species for easy field identification. Samples were taken from five trees for each species. Morphological trait identification was conducted by leaf observation and measurement. The results showed that all four species had the same apex shape. Six of the twelve morphological characteristic of the variable character can influence the morphological characteristics of the leaves, namely the roving leaf, leaf area, leaf length, aspect ratio, form factorand perimeter ratio of diameter. S. leprosula is similar to S. parvifolia, while S. ovalis is similar to S. guiso. Shorea leaf character S. parvifolia differentiated from S. leprosula, while Shorea ovalis similar to Shorea guiso. The LP variable (length from the base of the leaf to the widest point of the leaf) is a variable that can be used as aleaf morphological characteristic of the four Shorea which are compared because each one has a different value. S. ovalis has the highest LP value, followed by S. guiso and S. leprosula, while S. parvifolia has the lowest LP value. [ABSTRACT FROM AUTHOR] |
| Abstract (Indonesian): |
Shorea merupakan genus dari famili Dipterocarpaceae yang memiliki nilai ekologi dan ekonomi yang tinggi. Saat ini, pemenuhan permintaan pasar kayu masih berasal dari hutan alam, sehingga menyebabkan populasi pada habitat aslinya menurun. Hal ini menyebabkan perlunya dilakukan upaya penanaman. Identifikasi spesies merupakan langkah awal penting yang harus dilakukan dalam kegiatan penanaman, termasuk pada budidaya Shorea yang pada fase anakan sangat mirip satu sama lainnya, terutama pada karakter morfologi daun. Penelitian ini bertujuan untuk mengkaji karakter penciri morfologi daun empat jenis Shorea untuk memudahkan identifikasi di lapangan. Sampel daun diambil dari lima individu per spesies, dari setiap pohon diambil lima helai daun yang memiliki fenotipe terbaik. Identifikasi morfologi dilakukan dengan mengamati dan mengukur variabel morfologi sampel daun. Hasil penelitian menunjukan bahwa keempat spesies memiliki bentuk ujung daun yang sama. Enam dari duabelas variabel karakter penciri morfologi nilainya dapat mempengaruhi penciri morfologi daun yaitu keliling daun, luas daun, panjang daun keseluruhan, aspek rasio, form factor dan perimeter ratio of diameter. Karakter daun Shorea leprosula mirip dengan Shorea parvifolia, sedangkan Shorea ovalis mirip dengan Shorea. guiso. Variabel LP (panjang dari pangkal daun ke titik terlebar daun) merupakan variabel yang dapat dijadikan sebagai penciri morfologi daun dari keempat Shorea yang dibandingkan karena satu sama lain memiliki nilai yang berbeda. S. ovalis memiliki nilai LP paling tinggi, disusul S. guiso dan S. leprosula, sedangkan S. parvifolia memiliki nilai LP yang paling rendah. [ABSTRACT FROM AUTHOR] |
