In the last decades, several biochemical and molecular studies in pear (Pyrus spp.) have revealed processes associated with dormancy establishment release, leading to identification of MADS-box family genes related bud regulation. Thus, aim this study was evaluate a preliminary expression pattern PpDAM13-1 PpDAM13-2 leaf buds pyrifolia Nakai, cultivars Hosui Nijisseiki; Pyrus communis L., Rocha...

The effect of regulated de®cit irrigation (RDI) on fruit growth was studied for pear trees (Pyrus communis L. `Barlett') grown in 120 l isolated containers. Two irrigation treatments were applied in consecutive seasons (1996 and 1997) but on different trees each year. The Control treatment was watered to non-stress conditions using stem water potential (Cstem) and Penman ETo as a guide for the ...

Micropropagation of Kainth using nodal explants was carried out in tissue culture laboratory, Department of Fruit Science, Punjab Agricultural University, Ludhiana during 2011-13. The effect of various media {1/2 MS (M1), MS (M2) and WPM (M3)} and growth regulators (BAP, IBA and NAA) on establishment, proliferation and rooting was studied. Per cent necrotic culture was found to be influenced by...

Type-B response regulators (B-RRs) are transcription factors that function in the final step of two-component signaling systems. In model plants, B-RRs have been shown to play important roles in cytokinin signal transduction. However, the functions of B-RRs in pear have not been well studied. In this report, we conducted a genome-wide analysis and identified 11 putative genes encoding B-PpRR pr...
