Special Issue Information

Dear Colleagues,

The mechanisms of flowering regulation, flower production and flower organ senescence are not only important for understanding the basic knowledge in plants, but also for agricultural production such as in crops and ornamental plants. With the development of multi-omics tools and methods, we can dig out the core regulatory networks and genes related to these traits. Based on these, we have decided to launch this Special Issue titled “Advances in Molecular Mechanisms of Flowering Regulation, Flower Production and Flower Organ Senescence”.

This Special Issue welcomes contributions from researchers working in the fields of flowering regulation, flower production and flower organ senescence. Original research articles are encouraged for submission, focusing on, but not limited to, the following areas:

  • Flowering regulation;
  • Flower production;
  • Flower organ senescence.

We look forward to receiving your contributions.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The aim of the study was to assess the post-harvest life of the leaves of Hemerocallis × hybrida ‘Agata’, Limonium latifolium, and Heuchera hybrida ‘Chocolate Ruffles’ after the application of growth regulators from the group of gibberellins (GAs) and cytokinins (CKs), ionic liquids (2-hydroxyethyl)dimethylethylammonium gibberellinate [Chol][Gib] and acetylcholine gibberellinate [Gib][Ach]), as well as quaternary ammonium salts with the gibberellinate anion (1-ethyl quinine gibberellinate [Q-C2][Gib]) and 1-dodecyl acetylcholine gibberellinate [Q-C12][Gib]). The leaves were conditioned for 4 h in aqueous solutions of benzyladenine (BA), meta-methoxytopolin (MemT) and its riboside (MemTR), gibberellic acid (GA3), [Q-C2][Gib], [Gib][Ach], [Chol][Gib], and [Q-C12][Gib] at concentrations of 50 and 100 mg·dm−3. Conditioning of Hemerocallis × hybrida ‘Agata’ with MemT and [Chol][Gib] at both concentrations, [Q-C2][Gib] (100 mg·dm−3) and [Gib][Ach] (50 mg·dm−3), extended the vase life of the leaves by 7–9 days. The application of [Gib][Ach] (50 and 100 mg·dm−3) and [Q-C12][Gib] (100 mg·dm−3) resulted in the longest vase life of the leaves of Limonium latifolium. Conditioning of the leaves of Heuchera hybrida ‘Chocolate Ruffles’ with BA, MemT, and MemTR (50 and 100 mg·dm−3) extended their vase life by 9.5–51.3 days. BA at a concentration of 100 mg·dm−3 was the most effective. MemT (50 mg·dm−3), MemTR (100 mg·dm−3), [Q-C2][Gib] (100 mg·dm−3), [Gib][Ach] (100 mg·dm−3), and [Chol][Gib] (50 mg·dm−3) inhibited the degradation of proteins in the leaves of Hemerocallis × hybrida ‘Agata’; [Chol][Gib] (50 and 100 mg·dm−3)—in the leaves of Limonium latifolium; all the conditioners except for BA—in the leaves of Heuchera hybrida ‘Chocolate Ruffles’. GA3, MemTR, [Gib][Ach], [Q-C12][Gib] at both concentrations, [Q-C2][Gib], and [Chol][Gib] (50 mg·dm−3) inhibited the degradation of chlorophyll in the leaves of Hemerocallis × hybrida ‘Agata’. All conditioners except for [Gib][Ach] and [Q-C12][Gib] inhibited chlorophyll degradation in the leaves of Limonium latifolium. All conditioners except for MemT and MemTR (50 mg·dm−3) inhibited chlorophyll degradation in the leaves of Heuchera hybrida ‘Chocolate Ruffles’. [Chol][Gib] (50 mg·dm−3) was the most effective.

Since the 1990s, the world has seen an increased interest in Zantedeschia with colourful inflorescence spathes. In Poland, its cultivation began much later. The reasons for this phenomenon can be traced to the high price of rhizomes reproduced in the United States of America, the Netherlands, New Zealand and Kenya. The area of reproductive plantations is increasing every year, but this does not affect the decrease in the price of rhizomes, which is the main reason that only a few producers are cultivating Zantedeschia cultivars in Poland. Producers offer rhizomes in various sizes, with flowering expected only from the largest ones. However, the yield of cut flowers that can be obtained from them is often not very satisfactory and is not compensated by the price that can be obtained from the sale of the flowers. It is the low yield of cut flowers that is the main problem in the cultivation of Zantedeschia cultivars, hence research conducted worldwide focuses on the use of growth regulators from the group of cytokinins (CKs) and gibberellins (GAs) in the cultivation of Zantedeschia with colourful inflorescence spathes. The post-harvest life of flowers and leaves of cultivated Zantedeschia cultivars is also an important problem. This review presents the results of research conducted over the years to improve the flowering and post-harvest life of the flowers and leaves of Zantedeschia with colourful inflorescence spathes.
