Effects of different times and intensities of fructification pruning in camu-camu plants.
In order to generate more accurate agronomic management practices for the cultivation of camu-camu (Myrciaria dubia), a study was conducted to measure the effects of different timings and intensities of the plant fructification pruning. Materials and methods ? The study was conducted following a complete randomized block design in split plot arrangement with four repetitions composed of four plants per experimental unit by treatment. The plots were constituted of 4 pruning times (April, May, June and July of 2014) and the sub-plots by the following pruning intensities: short at 80 cm, medium at 120 cm, and long at 180 cm in height. The shoot number (SN) and shoot length (SL), the numbers of flowering buds (NFB), of small fruits (NSF) and harvested fruits (NHF) were measured. The evolution of some phenological characteristics was also recorded over time. Results and discussion ? Shortpruned trees had smaller numbers of shoots but greater shoot lengths, thus delaying flowering and significantly reducing fruit production. Independently of the pruning season, the camu-camu plants submitted to long pruning or tip removal presented a greater number of shoots, of flowering buds, small fruits and harvested fruits. Conclusion ? Long pruning in camu-camu plants allowed fructification in less time regardless of in which month it was performed and pruning on camu-camu plants stimulated the growth and development of fruitful branches, thus contributing to a sustainable fruit production every year.
