“…The function of adding Gandasil D to chrysanthemum flowers was to provide a nutrient supply for the organs of leaves, stems and flower crowns so that they were expected to have a longer freshness. This is in accordance with the research of Andalasari, et al (2014) which stated that the addition of Gandasil D in the hydrogel was thought to be able to increase the ability of plant organs to retain water content. According to Wiraatmaja, et al (2007) the wilting process is accelerated when the water loss is more than the absorption, causing the flower stalk to lack water, the lower the water absorbed by the flower stalk, the higher the percentage of wilted flowers.…”

Chrysanthemum sp. is one of the popular types of cut flowers and is in great demand by consumers because of its attractive shape, color, and varying sizes. This study aims to determine the effect of Gandasil D and its application method in maintaining the freshness of chrysanthemum flowers in hydrogel media. This study used a completely randomized design consisting of 2 treatment factors, namely the concentration treatment of Gandasil D (0%, 0.5%, and 1%) and the application of Gandasil D (soaking, spraying, and a combination of both). Parameters observed, among others; leaf wilting rate, flower freshness duration, leaf freshness duration, and flower wilting rate. The results of this study showed that the concentration of Gandasil D treatment had no significant effect on the freshness of chrysanthemum flowers, except for the length of leaf freshness parameter which showed that the concentration of Gandasil D 1% produced the longest leaf freshness among other treatments. The Gandasil D application method has a significant effect on the freshness of chrysanthemums. The single treatment of immersion or spraying resulted has a longer average flower freshness than the combination treatment, although the average value between soaking and spraying was not significant. The combination of concentration treatment and application method of Gandasil D had no significant effect on the freshness of chrysanthemums, except for the length of flower freshness parameter.

“…Nitrogen merupakan hal penting yang dibutuhkan sebagai salah satu penyusun protein pada tanaman. Ketersediaan unsur N pada tanaman akan berpengaruh pada pembelahan sel pada tanaman sehingga akan mempengaruhi pada pertumbuhan daun dan juga tinggi tanaman (Andalasari et al, 2014). Hasil pada tinggi tanaman dan jumlah daun tersebut menunjukkan adanya penyerapan unsur nitrogen yang baik pada kosentrasi kitosan sehingga tanaman memiliki jumlah daun dan tinggi optimal.…”

Anggrek Dendrobium merupakan salah satu tanaman hias yang bernilai ekonomis tinggi. Minat masyarakat pada anggrek khususnya jenis Dendrobium cukup tinggi dan mendominasi pasar sehingga kebutuhan bibit anggrek jenis ini juga semakin tinggi. Tahapan kritis dalam menentukan keberhasilan pertumbuhan bibit anggrek juga ditentukan oleh teknik aklimatisasi. Perbedaan kondisi lingkungan pada tahap aklimatisasi dapat menyebabkan planlet mengalami transpirasi berlebihan dan mengganggu penyerapan nutrisi. Kitosan sebagai bahan organik alami merupakan turunan sederhana dari kitin yang dapat berfungsi sebagai biofertilizer dan bioimmuner. Tujuan penelitian ini untuk mengetahui respon pertumbuhan bibit anggrek terhadap pemberian kitosan untuk keberhasilan tahap aklimastisasi. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu konsentrasi kitosan. Tahap aklimatisasi dengan menngunakan aplikasi kitosan dengan konsentrasi 0 ppm, 2 ppm, 2,5 ppm, 3 ppm, 3,5 ppm, 4 ppm, 4,5 ppm dan 5 ppm. Data yang diperoleh selanjutnya dianalisis ragam dengan uji F pada taraf 5%. Perlakuan yang berpengaruh nyata diuji lanjut dengan Duncan Multiple Range Test (DMRT) pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa pemberian kitosan dengan konsentrasi 3 ppm berpengaruh nyata dalam meningkatkan parameter presentase tumbuh tanaman, tinggi tanaman, jumlah daun, lebar daun, panjang daun, panjang akar, jumlah akar, dan berat segar tanaman anggrek Dendrobium sonia pada tahap aklimatisasi.

“…Angka tersebut diperoleh melalui persamaan garis regresi Y = 1,398 + 1,308 x -0,511 x 2 , dan R 2 = 89% pada umue 4,5 bulan. Bibit anggrek yang diberi Gandasil B dapat menghasilkan anakan sebanyak 3,83 pada umur enam bulan, (Andalasari et al, 2003) Panjang daun optimum diperoleh dengan pemberian Grow Quick LB dengan konsentrasi 0,3 cc/liter air. Lebar daun dan jumlah tunas optimum diperoleh dengan pemberian Grow Quick LB dengan konsentrasi 0,2 cc l -1 air.…”

The purpose of the research was to obtain concentration Grow Quick LB optimum for growth of seedlings of Orchid Dendrobium Sp.Environmental design used was complete Random Design. The design of the treatment given is concentration Grow Quick LB 0 cc l-1 water, 0.5 cc l-1 water, 1cc l-1 water, 1.5 l -1water, 2 ccl-1 water, and 2.5 cc l-1 water.The data obtained were analyzed using polynomial regression. The research results obtained that the higher seed, and number of leaves of Dendrobium orchids with optimum pemberianGrow Quick 1.5 LB cc l-1. of water.Optimum leaf length is obtained by the giving Grow Quick LB with a concentration of 0.3 cc l-1 of water.The width of the leaves and shoots of the optimum amount is obtained by granting the Grow Quick LB with a concentration of 0.2 cc l-1 of water.
