Polyploid plantlets, including triploid, tetraploid, and mixoploid, were induced from the European pear (Pyrus communis L.) cultivar ‘Fertility’ by in vitro colchicine treatment of leaf explants. The leaf explants were incubated in 0.4% (w/v) colchicine for 24, 48, or 72 h, then transferred to adventitious shoot-induction medium. Regenerated shoots were pre-selected according to their morpholog...

Patharnakh pear fruits were freshly harvested at the physiological maturity during second week of July and subjected to different precooling treatments, viz. Hydrocooling (HC), Forced Air Cooling (FAC) Evaporative (EC). The effect these methods on fruit shelf-life quality attributes under ambient conditions was investigated year 2021–22 Punjab Horticultural Post harvest Technology Centre, Agric...

Wizened buds are frequently observed in pear (Pyrus spp.) trees, which greatly reduces the yield. However, little is known about mechanism of wizened bud formation. Here, we analyzed physiological and transcriptomic differences between normal ‘710’ trees. The results indicated that sorbitol boron (B) contents, during differentiation, were significantly reduced buds. microscopic observation tran...
