The midto long-term preservation of papaya (Carica papaya L.) would allow for the safeguarding of important germplasm. In this study, soft friable callus (SFC) and hard callus (HC) were induced from the first two true leaves of 10-day-old seedlings containing a midrib derived from the germinated seed of two cultivars (‘Rainbow’ and ‘Sunrise Solo’). Following germination on a Murashige and Skoog...

BACKGROUND AND AIMS The control of dormancy in yam (Disocorea spp.) tubers is poorly understood and attempts to shorten the long dormant period (i.e. cause tubers to sprout or germinate much earlier) have been unsuccessful. The aim of this study was to identify and define the phases of dormancy in Dioscorea rotundata tubers, and to produce a framework within which dormancy can be more effective...

Lamprocapnos spectabilis (L.) Fukuhara (bleeding heart) is valued both in the horticultural and pharmaceutical markets. Despite its great popularity, information on vitro tissue culture technology this species limited. There also little knowledge application of plant extracts systems plants other than orchids. The aim study to compare utility traditional growth regulators (PGRs) natural extract...

Abstract The effect of the biopreparation Rizotorfin and growth regulators Albit, Kornevin, Epin-Extra on symbiotic activity yield bean plant varieties Geliada Shokoladnitsa was studied under field conditions. nitrogenase increased in Heliada plants after treatment seeds with against increase bacteroides area, amount area volutin decrease poly-ß-oxybutyric acid (POM). protective evident variety...

Callus induction and regeneration of fennel from embryo explants were stabilized in the presence of cefotaxime antibiotic and different plant growth regulators (PGRs). The experiments were conducted under a factorial experiment, based on a completely randomized design (CRD). Genotypes; Fasa, Meshkinshar and Hajiabad were applied under different concentration of cefotaxime (0 and 100 mg l-1...

The diverse effects of the plant hormone ethylene on development and growth are shaped by the actions of a master regulator of transcription, EIN3.

Research of the molecular events underlying brassinosteroid (BR) signaling is emerging as a new paradigm for studying plant hormone signal transduction pathways. Two recent reports have shown that the BZR1-BES1 family of proteins is a class of novel plant-specific transcription factors that directly bind to and regulate BR-responsive genes, thus filling in key details of the link between hormon...

Sugarcane problems in germination will effect on growth and the yield that is not optimal. The solution obtained from these plant regulators soaking storage time bud sett seedling before planting. This study used a factorial experimental method with first factor being consisting of 3 levels, namely 0 days (control), 1 day, 2 days. second was PGR which consisted control (without soaking), NAA + ...

Small molecules capable of uncoupling growth-defense in plants are currently not known. In this study, for the first time, semi-synthetic analogues of the phytohormone JA-Ile are employed to uncouple growth and defense responses in wild tobacco. The JA-Ile analogues are easily synthesized from inexpensive substrates via olefin metathesis.

We describe a method for the simulation of the growth of elongated plant organs, such as seedling roots. By combining a midline representation of the organ on a tissue scale and a vertex-based representation on the cell scale, we obtain a multiscale method, which is able to both simulate organ growth and incorporate cell-scale processes. Equations for the evolution of the midline are obtained, ...
