In the production and breeding of Chrysanthemum sp., shoot branching is an important quality aspect as the outgrowth of axillary buds determines the final plant shape. Bud outgrowth is mainly controlled by apical dominance and the crosstalk between the plant hormones auxin, cytokinin and strigolactone. In this work the hormonal and genetic regulation of axillary bud outgrowth was studied in two...

Saffron (Crocus sativus L.) is one of the most important and expensive medicinal spice products in the world. Because of its high market value and premium price, saffron is often adulterated through the incorporation of other materials, such as Carthamus tinctorius L. and Calendula officinalis L. flowers, Hemerocallis L. petals, Daucus carota L. fleshy root, Curcuma longa L. rhizomes, Zea may L...

Chrysanthemum chlorotic mottle viroid (CChMVd) is an RNA of 398-399 nt that can adopt hammerhead structures in both polarity strands. We have identified by Northern-blot hybridization a nonsymptomatic strain (CChMVd-NS) that protects against challenge inoculation with the symptomatic strain (CChMVd-S). Analysis of CChMVd-NS cDNA clones has revealed a size and sequence very similar to those of t...

Previous studies of highly branched mutants in pea (rms1-rms5), Arabidopsis thaliana (max1-max4), petunia (dad1-dad3), and rice (d3, d10, htd1/d17, d14, d27) identified strigolactones or their derivates (SLs), as shoot branching inhibitors. This recent discovery offers the possibility of using SLs to regulate branching commercially, for example, in chrysanthemum, an important cut flower crop. T...

A field experiment was conducted to study the short-term impact of sensor-based wastewater irrigation scheduling on chemical soil health in chrysanthemum (Chrysanthemum morifolium Ramat.) at Water Technology Centre, ICAR-Indian Agricultural Research Institute (IARI), New Delhi during 2019–20. Experiment with following 6 treatments, viz. T1, Groundwater (GWI) 25% Maximum Allowable Depletion (MAD...
