RESEARCH ON POLLEN VITALITY CORRELATED TO METEOROLOGICAL CONDITIONS AT ROMANIAN VARIETIES OF PEACH AND NECTARIN
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
In order to know exactly the productive potential of a variety(genotype) and for choosing pollinator (genitor), to create new varieties, as well as for the anticipated appreciation of the economic results, methods are used to verify the viability of pollen by specific enzymatic methods, as well as its germination, on different cultural backgrounds. In the present paper it is investigated in vitro and it is evaluated microscopically, the vitality of pollen in some Romanian peaches and nectarine varieties, in order to evaluate the yield of pollen %R(G/V) germination in the conditions given by the experiment, relationship expressed through germination capacity and mature pollen viability from fresh anthers.There were evaluated three peach varieties Amalia, Congress and Splendid, and also two varieties of nectarines Tina and Mihaela. The best performance (yield) in germination was recorded in the liquid medium with sucrose of 20%, having as leaders for peach Amalia and Splendid varieties, and for nectarine having as leader Mihaela variety.
