“…The selection of boric acid dose and the time of application was based on previously published reports (Ziogas et al, 2020). The cultivar “Skeena” was chosen because it is self‐fertile (Kappel et al, 2003). Three biological replicates of 15 branches harvested from 5 trees ( 3 branches per tree) were analyzed for boron treatment and control .…”

Boron modulates a wide range of plant developmental processes; however, the regulation of early fruit development by boron remains poorly defined. We report here the physiological, anatomical, metabolic, and transcriptomic impact of pre‐flowering boron supply on the sweet cherry fruit set and development (S1–S5 stages). Our findings revealed that endogenous boron content increased in early growth stages (S1 and S2 stages) following preflowering boron exogenous application. Boron treatment resulted in increased fruit set (S1 and S2 stages) and mesocarp cell enlargement (S2 stage). Various sugars (e.g., fructose and glucose), alcohols (e.g., myo‐inositol and maltitol), organic acids (e.g., malic acid and citric acid), amino acids (e.g., valine and serine) accumulated in response to boron application during the various developmental stages (S1–S5 stages). Transcriptomic analysis at early growth (S1 and S2 stages) identified boron‐responsive genes that are mainly related to secondary metabolism, amino acid metabolism, calcium‐binding, ribosome biogenesis, sugar homeostasis and especially to photosynthesis. We found various boron‐induced/repressed genes, including those specifically involved in growth. Several heat shock proteins displayed distinct patterns during the initial growth in boron‐exposed fruit. Gene analysis also discovered several putative candidate genes like PavPIP5K9, PavWAT1, PavMIOX, PavCAD1, PavPAL1 and PavSNRK2.7, which could facilitate the investigation of the molecular rationale underlying boron function in early fruit growth. Substantial changes in the expression of numerous transcription factors, including PavbHLH25, PavATHB.12L, and PavZAT10.1,.2 were noticed in fruits exposed to boron. The current study provides a baseline of information for understanding the metabolic processes regulated by boron during sweet cherry fruit early growth and fruit development in general.

Determination of the most optimal types and concentrations of plant growth regulators as medium constituents is one of the most important aspects of successful micropropagation, among other in vitro factors. With the aim of optimization of in vitro multiplication of sweet cherry cv. Lapins the effect of following cytokinins has been studied: benzyladenine (BA), isopentenyl adenine (2iP), kinetin (KIN) and thidiazuron (TDZ) at concentrations of 1, 2, 5, 10 and 15μM, combined with auxine, indole-3-butyric acid (IBA) at concentrations of 0, 0.5, 2.5 and 5μM. Murashige and Skoog (1962) was the basic medium used in all the combinations. The following multiplication parameters were monitored: multiplication index, length of axial and lateral shoots. Fresh and dry shoot weight (callus, stem and leaves -S + L) were determined. Some specific issues, such as colour, leaf and callus size, leaf roll, incidence of chlorosis or necrosis along with occurrence of rhizogenesis, i.e. roots unusual for this phase of micropropagation, were also monitored. The highest multiplication index as well as length of axial and lateral shoots was obtained on media with BA. Very poor multiplication, with large sized shoots and big leaves, was achieved on media with 2iP, TDZ and KIN, whereas in many combinations with 2iP, and particularly in those with KIN, rhizogenesis was induced. Obtained results suggest that the choice of cytokinins for the phase of multiplication of sweet cherry is limited to BA. For more rapid micropropagation, through joining rooting and multiplication phases, KIN and 2iP may be applied. The latter two may be also used to obtain sturdy shoots (elongation phase, prior to rooting).
