Alstromeria is a new cut flower in Iran that due to the high performance, long life, and pretty flowers and colors diversity is highly regarded. Premature yellowing of leaves in cut flowersAlstromeria before petal fall is the most important factor limiting the vase life of flowers. To delay leaf yellowing and increased quality, factorial experiment based on completely randomized design carried ...

A protocol for direct organogenesis in Bixa orellana (pink flowers variety) has been developed with significant organogenic response from rooted hypocotyls, hypocotyl segments, and cotyledonary leaf explants on Murashige and Skoog (MS) medium supplemented with 2.0 mg L thidiazuron and 0.25% coconut water or 7.0 mg L N-Benzyladenine and 0.1 mg L a-naphthalene acetic acid. Thidiazuron in combinat...


 Tujuan dari penelitian ini untuk mengetahui efektivitas penambahan Zat Pengatur Tumbuh ( ZPT) pada pertumbuhan tunas dan perakaran stek mikro kulit umbi tanaman porang (Amorphophallus muelleri blume) talas beneng (Xanthosoma undipes k.koch). Rancangan Acak Lengkap (RAL) digunakan dalam dengan 8 perlakuan : Z1 = tanpa ZPT, Z2= + Auksin 1,5 ml/L, Z3= +Thidiazuron 1 ppm, Z4= +Auksin ml/L Th...

A protocol for micropropagation of Boswellia ovalifoliolata Bal & Henry (Burseraceae) was developed using cotyledonary nodal explant on Murashige and Skoog modified medium (MS). A comparative study of micropropagation with 6-benzyladenine, kinetin and thidiazuron along with 1-naphthalene acetic acid (0.054 microM) was conducted. The highest shoot multiplication (7.1 +/- 0.2 shoots per node) was...

Somatic embryogenesis was induced in hypocotyl explants of geranium (Pelargonium x hortorum) cultured on media supplemented with various concentrations of N-phenyl-N'-1,2,3-thiadiazol-5-ylurea (thidiazuron). In less than 2 weeks, somatic embryos were observed in treatments containing levels of thidiazuron (TDZ) ranging from 0.2 to 1.0 micromolar. The use of N(6)-benzylaminopurine in combination...

conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. a general prerequisite for these approaches is to establish an efficient plant reg...

to study the effect of nitric oxide on longevity and some qualitative characteristics of cut carnation flowers (dianthus caryophyllus cv. nelson), cut flowers were treated for 48 hours with sodium nitroprusside (snp) as a source of no° donor at four concentrations (0, 20, 50 and 100µm) alone and in combination with other such ethylene inhibitors as thidiazuron and sucrose in a completely random...

abstract gerbera is one of the most demanded plants in commercial cut flowers plants. optimizing the micro-propagation of new cultivars is therefore important. in this research “red explosion” cultivar was used and capitola (as explants) were directed to a modified solid murashigue and skoog medium with four concentration of tdz (0.25, 0.50, 0.75 and 1.00 mgl-1) for regeneration. three concentr...
