“…As occurs in other woody perennials, growth and dormancy cycles coordinate with the seasons (Rohde and Bhalerao, 2007). Blooming in sweet cherry, as in other temperate fruit trees, lasts for a few days only, but flower buds develop over months (Mounzer et al, 2008;Koutinas et al, 2010;Andreini et al, 2012). Flower differentiation takes place at the end of the previous summer.…”

In order to survive to low temperatures, fruit trees in temperate regions stop their growth and enter dormancy. This is not just a survival strategy; chilling is also a prerequisite for adequate flowering. Chilling requirements are specific for each genotype and determine the possible geographical distribution of the different cultivars. In spite of the relevance of dormancy for fruit production, very little is known on the biological events during this time in flower buds, in which no visible changes can be observed until bud burst. In this work, flower bud development has been sequentially examined in sweet cherry (Prunus avium L.) cv "Bing" grafted on Santa Lucia 64 rootstock, in relation to dormancy and chilling accumulation. The work was performed over two consecutive years, paying attention to the possible anatomical and cytochemical changes accompanying dormancy. Results showed that, while no anatomical variations occurred along dormancy, conspicuous cytochemical changes could be tracked along this period that may help to understand the requirement for chilling.

“…A bourse can subsequently form a sylleptic axillary shoot (''bourse shoot'') that can finally develop into a short or long shoot (Costes and Guédon 2002). The decision whether a bud turns into a flower/fruit or shoot is controlled by various factors such as cultivar, rootstock, shoot growth and phytohormones (Hoad 1984;Buban 1996;Koutinas et al 2010). Cessation of apical elongation growth and bud set are the first steps to winter dormancy.…”

Tracing a key player in the regulation of plant architecture: the columnar growth habit of apple trees (Malus × domestica)

Plant architecture is regulated by a complex interplay of some key players (often transcription factors), phytohormones and other signaling molecules such as microRNAs. The columnar growth habit of apple trees is a unique form of plant architecture characterized by thick and upright stems showing a compaction of internodes and carrying short fruit spurs instead of lateral branches. The molecular basis for columnar growth is a single dominant allele of the gene Columnar, whose identity, function and gene product are unknown. As a result of marker analyses, this gene has recently been fine-mapped to chromosome 10 at 18.51-19.09 Mb [according to the annotation of the apple genome by Velasco (2010)], a region containing a cluster of quantitative trait loci associated with plant architecture, but no homologs to the well-known key regulators of plant architecture. Columnar apple trees have a higher auxin/ cytokinin ratio and lower levels of gibberellins and abscisic acid than normal apple trees. Transcriptome analyses corroborate these results and additionally show differences in cell membrane and cell wall function. It can be expected that within the next year or two, an integration of these different research methodologies will reveal the identity of the Columnar gene. Besides enabling breeders to efficiently create new apple (and maybe related pear, peach, cherry, etc.) cultivars which combine desirable characteristics of commercial cultivars with the advantageous columnar growth habit using gene technology, this will also provide new insights into an elevated level of plant growth regulation.

“…Flower bud development is a highly complex process that is characterized by two distinct physiological phases: floral initiation and floral bud development (Fan et al, 2015;Koutinas et al, 2010). The formation of peony flower buds and their related developmental events are controlled by multi-ple genetic factors (Ge et al, 2014), and these are influenced by seasonal changes in daylength and temperature (Zhang et al, 2015).…”

“…Prolonged chilling before forcing at warm temperatures promotes the release of dormancy, but it is commonly accepted that low temperature is sensed by the shoot apical meristem only after the bud reaches a certain stage of development (Barzilay et al, 2002). Thus, the synchronization of environmental conditions and bud differentiation is critical for the flowering time of plants, and is of great importance to sustainable cut flower or potted plant production (Koutinas et al, 2010).…”

Additional index words. bud development, flower type, herbaceous peony, observation methods of bud differentiationAbstract. The analysis of herbaceous peony (Paeonia lactiflora Pall.) floral bud initiation and differentiation from autumn to early spring is important because flower formation is strictly correlated with flowering in late spring. A clear understanding of peony flower development would allow management practices to be optimized for stable annual production and supply of cut flowers. The aim of this research was to study the timesensitive characteristics underlying flower development in peony cultivar 'Dafugui'. Flower bud differentiation was assessed by paraffin and hand-made slices, as well as stereomicroscopy. Both methods have strengths and weaknesses. Our observations are not entirely consistent with those of previous studies. Flower bud differentiation in 'Dafugui', which starts from late September to mid-April of the following year, is divided into differentiation of the lower parts (separate differentiation periods for the bracts, sepals, petals, stamens, and pistillodes) and upper parts (separate differentiation periods for the petals, stamens, and pistil), and is closely related to annual changes in ambient temperature. Differentiation of lower flower buds takes place before winter dormancy, whereas that of upper parts starts early in the following spring, and finally forms a double-flowered type. The three methods used in this article can be used to study P. lactiflora flower bud differentiation and can contribute to an understanding of this process in the future.
