Abstract

Tembakau lokal tulungagung merupakan salah satu jenis tembakau yang  memiliki peran penting dalam industri rokok kretek di Indonesia. Beberapa varietas tembakau telah banyak dibudidayakan di wilayah Kabupaten Tulungagung, tetapi tingkat heterogenitas tanaman cukup tinggi, baik secara morfologi maupun anatomi. Stomata merupakan salah satu bagian struktur daun yang sering digunakan dalam klasifikasi taksonomi sehingga informasi keragaman sifat morfologi, stomata dan kadar klorofil dapat dimanfaatkan pemulia tanaman untuk melakukan perakitan varietas baru dengan produktivitas sesuai dengan kebutuhan konsumen. Tujuan penelitian ini adalah untuk mempelajari keragaan sifat morfologi, stomata, dan kadar klorofil serta produktivitas tanaman. Penelitian ini dilaksanakan di Desa Kendalbulur, Kecamatan Boyolangu, Kabupaten Tulungagung, pada bulan April sampai Oktober 2015.  Bahan penelitian terdiri atas 6 varietas tembakau yang sudah lama berkembang di Tulungagung, yaitu varietas Rejeb Arang, Rejeb Kerep, Gagang Sidi, Gagang Jembrak, Gagang Ijo, dan Rejeb Jae. Tiap-tiap varietas ditanam pada petak berukuran 12 m x 4,50 m dengan jarak tanam 60 cm x 90 cm (100 tanaman/petak).  Penelitian ini menggunakan rancangan acak kelompok dengan tiga ulangan.  Hasil penelitian menunjukkan bahwa 6 varietas tembakau yang diteliti mempunyai bentuk morfologi yang beragam. Varietas Rejeb arang memiliki nilai tertinggi pada karakter tinggi tanaman, jumlah daun, dan pajang daun, sehingga dapat menunjang produktivitas tanaman.  Tipe stomata Rejeb Arang adalah Amphibraci-parasitik, Rejeb Kereb dan Gagang Jae Diasitik, Gagang Sidi dan Gagang Ijo bertipe Anisositik sedangkan Gagang Jembrak bertipe Laerositik.  Kerapatan stomata tertinggi pada Gagang Jae (44,87/mm2) dan kadar klorofil tertinggi pada varietas Rejeb Arang (34,85 unit).Performance of Morphological, Stomata, and Chlorophyll Characters of Six Tulungagung Local Tobacco Variety Tulungagung tobacco is one type of tobacco that has an important role in the cigarette industry in Indonesia. Some varieties of tobacco have been cultivated in Tulungagung, but the heterogeneity degree of the plant is quite high, so that the information of diversity of morphology, stomata and chlorophyll can be utilized to carry out the assembly of new varieties with productivity in accordance to customer needs. The aim of research is study  the morphological properties, stomata, chlorophyll content, and crop productivity. This research was conducted in the village of Kendalbulur, District Boyolangu, Tulungagung, from April to October 2015. The research material consisted of six varieties of tobacco has long been developing in Tulungagung, ie Rejeb Arang, Rejeb Kerep, Gagang Sidi, Gagang Jembrak, Gagang Ijo, and Rejeb Jae. Each variety was grown on plots sized 12 m x 4.50 m with plant spacing of 60 cm x 90 cm (100 plants/plot). This study used a randomized complete block design with three replications. The results showed that six varieties of tobacco studied have varying morphology. Varieties Rejeb charcoal has the highest value on plant height, leaf number, and leaf length, so that could support the productivity of the plant. Stomata type of Rejeb Arang is Amphibraci-parasitic, Rejeb Kereb and Rejeb Jae are Diasitic, Gagang Sidi and Gadang Ijo are Anisositic; Gagang Jembrak is Laerositik. The highest chlorophyll content was in Rejeb Arang varieties (34.85 units).

Abstract

One of the problems encountered in the development of sugarcane (Sacharrum officinarum L.) includes the availability of sugarcane seed both in quality and quantity. Evaluation of bud sett planting method in seed production was required in order to achieve the expected results. The study was conducted at the experiment station Muktiharjo, Central Java in 2012 using PSJT 941 varieties. Treatments applied were the different number of buds on bud sett which were at 3 levels, 1 bud, 2 buds or 3 buds. Research was arranged in a randomized complete block design (RCBD) with 5 replications. Observations were conducted on germination, tillering, plant height, number of stems, number of suckers and number of buds. The data obtained were analyzed with ANOVA and further tested using the Duncan test. Production assessment modeling approach was performed by a regression analysis. Calculation of stem number on 2 buds showed the highest with 9.6 stems/m, 9.2 buds/stem and with the sucker numbers lowest at 0.38 suckers/m. The highest production buds was obtained at planting 2 buds with 847,848.06 buds/ha which can be used as 8.83 ha for the milled sugarcane plantation. Assessment of bud production per hectare could use equation Y = 159655,48.e0,171.X with the independent variable of stem numbers per meter with a correlation coefficient of 0,9007 and a standard error of 1,0699.
