Cell expansion is crucial for plant growth. It is well known that the phytohormone ethylene functions in plant development as a key modulator of cell expansion. However, the role of ethylene in the regulation of this process remains unclear. In this study, 2,189 ethylene-responsive transcripts were identified in rose (Rosa hybrida) petals using transcriptome sequencing and microarray analysis. ...
El uso excesivo de agroquímicos para nutrir y controlar plagas encultivo rosa (Rosa x hybrida) conlleva costos ambientales económicos, por lo que se buscan alternativas disminuir su utilización. objetivo la presente investigación fue obtener un compost elaborado con vegetales aportan silicio y, evaluar efecto en cuatro ciclos productivos cv. Freedom®, sobre incidencia araña roja (Tetranychus ur...
رز یکی از مهمترین گیاهان زینتی است. هدف از انجام این تحقیق تولید جنینهای سوماتیکی و سپس باززایی کامل گیاه رز از جنینهای سوماتیکی میباشد. به این ترتیب بعد از کشت جوانه های جانبی گل رز هفت رنگ در محیط درون شیشه، برگهای مناسب آنها به عنوان ریزنمونه اولیه انتخاب گردیدند و برای کالوس زایی در شرایط تاریکی و دمای ?c25 کشت شدند. از بین 38 تیمار هورمونی در محیط ms و 16 تیمار هورمونی در محیط b5، محیط...
in vitro propagation of plant has played a very important role in rapidmultiplication of cultivars with desirable traits and production of healthy and disease-free plants. in the present investigation, the objectives were to optimize the micropropagation of rose hybrid ‘black baccarat’ cultivar. in proliferation step, the nodal segments (1.5 cm) was cultured on both liquid and solid media (ms, ...
Rose (Rosa hybrida) flowers produce and emit a diverse array of volatiles, characteristic to their unique scent. One of the most prominent compounds in the floral volatiles of many rose varieties is the methoxylated phenolic derivative 3,5-dimethoxytoluene (orcinol dimethyl ether). Cell-free extracts derived from developing rose petals displayed O-methyltransferase (OMT) activities toward sever...
microspore culture was applied to induce embryogenesis in roses (rosa hybrida) cv. hav1. important factors affecting viability of isolated microspores and formation of multi-cellular structures including isolation media (nln, ab, b) and induction media were studied. the most responsive developmental stage of microspores (late unicellular) was determined using dapi staining. the least infection ...
