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...

Plant cell suspension cultures are widely used for the production of recombinant proteins and secondary metabolites. One of the most important steps during process development is the optimization of yields by testing different cultivation parameters, including the components of the growth medium. However, we have shown that the biomass yield of a cell suspension culture derived from the pear cu...

This study was aimed at evaluating the antioxidant and antidiabetic activities of methanolic extracts peel, flesh mixed flesh, as well cytotoxic activity peel obtained from fruits six traditional pear varieties (Vidovaca, Lubenicarka, Karamanka, Jeribasma, Loncara Takisa), one commercial variety (Williams Bartlett) a wild (Pyrus communis) Serbia. The tested showed strong regarding prevention ?-...
