Effect of genotype and leader type on benzyladenine induced sylleptic branching in apple nursery trees

Kishan Lal Kumawat, Wasim Hassan Raja, Javid Iqbal Mir, Susheel Kumar Raina

Hort. Sci. (Prague), 2025, 52(1):33-41 | DOI: 10.17221/139/2023-HORTSCI  

The planting of branched nursery trees is an essential component of most high-density orchard planting systems to induce precocity. However, in apples, most cultivars do not produce the desired numbers of sylleptic shoots naturally due to the presence of apical dominance. Benzyladenine (BA) applications alter the apical dominance and consequently encourage sylleptic shoot formation in nursery trees. However, the response to an exogenous BA application can vary with the genotype. Currently, most nurseries produce branched apple nursery trees using the renewal leader method. However, apart from the renewal leader method, branched nursery trees can also...
