CHEMICAL THINNING RESULTS OF APRICOTS

The apricot is alterning bearing species.
This character originate its from genetical and ecological properties, i.e. climatological, phythopathological and phythotechnical factors affect by the yield.

The scientists tried out some chemicals as NAA, NAd, kali salt of NAA, Servine, MH, 2, 4, 5-T, 2, 4, 5-TP, Ethrel, etc.
The doses, dates (of applications), properties of chemicals are very different and contradictional and are in relationship with varieties (Fisher, 1963, Riccardi, 1970, Stadler, 1970; Surányi, 1978 a and 1978b).

Owing late frosts, because the author employed possibilities of questions of later thinning, recently he give a model of late chemical thinning of apricot varieties.
