“…The others believed that root pruning provided appropriate growth control and produced the highest yield due to an important increase in return bloom (Asín 2007). In the study, no significant difference was observed but there was a little increase in yield, partly owing to the recovery of root system and subsequent higher nutrient uptake for jujube tree in the later growth stage.…”

The effects of root pruning on the vegetative growth and fruit quality of six-year-old Zhanhuadongzao (Ziziphus jujuba Mill.) trees were evaluated. Three root pruning treatments (severe, moderate and light degree) were conducted at the distance of 3, 5 and 7 times trunk diameter from trunk on both inter-row sides of the trees, respectively. The results showed that the severe root pruning decreased the length of primary branch by 27.9% and the number of primary branches by 12.1% in contrast to the control of no root pruning. Compared to the control, both severe and moderate root pruning had no apparent effects on nitrogen, phosphorus and potassium contents of leaves after 35 days, but had significant effects after 161 days. Severe root pruning had larger effectiveness of controlling vegetative growth than the moderate one. By root pruning, the contents of vitamin C and total sugar were increased but the content of cypermethrin was decreased in fruits and no effects were found on total acid content of fruit and yield at harvest. In the rhizosphere soil, root pruning decreased the microbial populations and enzymes activities but increased the concentrations of cypermethrin, available nitrogen, phosphorus and potassium. It is proposed that the removal of root at 3 times trunk diameter distance from trunk was feasible to regulate the vegetative growth and fruit quality of Zhanhuadongzao tree.

“…Combined action of these elements may cause different promotion or control effects on growing development and fruit quality. Besides apple trees, root pruning is also reported to be used to reduce vegetative growth in a Blanquilla pear orchard (Asín et al 2007). However, no research is available on the application of root pruning in jujube trees.…”

Menores crecimientos también se han reportado con PBZ en pera (Asin et al, 2007), en nuestro estudio los mejores resultados se obtuvieron con P-Ca probablemente por el uso de dosis más altas que las utilizadas en pera.…”

La producción irregular en mango se atribuye a variación en la floración. Prohexadiona de calcio (P-Ca) reduce crecimiento vegetativo y favorece floración en frutales templados como manzano y subtropicales como aguacate. En mango ‘Ataulfo’, no hay información al respecto. El objetivo fue determinar dosis, época y número de aplicación de P-Ca en mango ‘Ataulfo’ con la finalidad de asegurar f loración y encontrar un sustituto para paclobutrazol (PBZ). El estudio se realizó de 2012 a 2014 en Tepic y San Blas Nayarit, en ambos años, los árboles fueron podados después de cosecha. Experimento 1 y 2: P-Ca (150, 250 y 500 mg L-1) a 0+10+20+30 días después de la poda (ddp) y 30+45+60 ddp, respectivamente. Experimento 3: P-Ca (500 mg L-1) una, dos o tres aplicaciones a 0, 0+10 y 0+10+20 ddp y Experimento 4: P-Ca (150 y 500 mg L-1) a 30+45+60 ddp y 1 500 mg L-1 en una sola aplicación (1 x) 30 ddp. En todos los experimentos se incluyó un tratamiento estándar de PBZ (2 500 mg L-1) 30 ddp y un testigo (agua más surfactante). El diseño fue completamente al azar, 6 repeticiones, un árbol como unidad experimental. En Experimento 2, se logró reducir un 35% el crecimiento vegetativo con P-Ca 500 mg L-1 (3 x) entre 30-60 ddp. Esta misma dosis de P-Ca (500 mg L-1) (3 x) a 30, 45 y 60 ddp, o una sola aplicación (1 500 mg L-1) 30 ddp logró igual el efecto de PBZ en adelanto (20-35 días) y porcentaje de floración. En los dos ciclos, ambos productos mejoraron amarre y producción de fruto. Con base a los resultados obtenidos se considera que P-Ca pudiera ser un sustituto para PBZ en mango ‘Ataulfo’ para asegurar floración y producciones regulares año con año.
