“…Câmara et al (2016) [39] reported positive influences on the survival and sprouting rates of mini-cuttings of acerola with C. rotundus applications. Silva et al (2011) [40] also detected beneficial results using C. haspan for rooting sugarcane.…”

Cyperus rotondus tubers possess substances with allelopathic qualities. Some of these substances can act as synergists of plant hormones and be used for root induction in cuttings. This study aimed to shed light on the development and rooting of Eucalyptus urophylla cuttings treated with C. rotondus (nutgrass) tuber extract and IAA (indole-3-acetic acid). The experiments were conducted using a completely randomized design (0; 25; 50; 75 and 100% nutgrass extract and 0; 50; 250; 500; 750 and 1000 mg L-1 of IAA), with four repetitions per treatment and four cuttings per plot. Plantlet height, stem width and root length were measured. The greatest width and height values were recorded for the control (0% nutgrass extract and 0 mg L-1 of IAA), indicating that these substances did not contribute to the development of these variables. However, treatments of nutgrass extract up to 50% were associated with greater root length. C. rotundus extract concentrations of 53% can be used to improve root development in E. urophylla cuttings, and contribute to the production of higher quality plantlets.

“…Regarding the number of roots per minicutting, the highest score was obtained with the application of 1,000 mg L -1 of IBA, reaching a total of 19.63 (Table 2). Câmara et al (2016) mentioned that the translocation of carbohydrates from the leaves to the base of the minicutting, as well as the production of auxins and other cofactors of rooting, may have promoted stimulation to root initiation in acerola trees (Malpighia glabra L.), and such fact may have cooperated for the higher number of roots per minicutting. In this study, the minicuttings that were not treated with IBA presented the lowest number of roots, in spite of presenting higher foliar retention, together with the concentration of 1,000 mg L -1 .…”

“…An adaptation of conventional cutting is the minicutting (Moreira et al, 2017) that is used in the production of not only O. europaea cv. Barnea (Moreira et al, 2017) and Arbequina (Casarin et al, 2017;Casarin et al, 2018), but it was also tested for the production of various fruit species such as soursop (Annona muricata L.) (Figueirêdo et al, 2013), 'pitangueira'(Eugenia uniflora L.) (Peña et al, 2015), and the acerola cherry tree (Câmara et al, 2016).…”

This study aims to evaluate the effect of etiolation and the usage of indolbutyric acid (IBA) in the propagation of Olea europaea cv. Maria da Fé minicuttings. The experimental outline is a completely randomized design, with a 2 x 3 bifactorial scheme [minicuttings from plants with and without etiolation and three concentrations of indolbutyric acid (0, 1,000, and 2,000 mg L -1 )]. After 110 days, the following has been evaluated: percentage of survival, foliar retention and rooting, number of roots, length of the largest root, root dry matter mass and percentage of unrooted minicuttings with calluses. For the percentage of survival, foliar retention and rooting, number of roots and root dry matter mass, there has only been significance for IBA concentrations, and in general, the IBA 1,000 mg L -1 concentration provided the highest scores. For the length of the largest root and minicuttings with non-rooted callus, there has been interaction between treatments, with the lowest scores for callus formation in the minicuttings with etiolation and without IBA. It can be concluded that the minicutting of Olea europaea cv. Maria da Fé can be carried out without etiolation in the mother plants, using 1,000 mg L -1 of IBA.

Wastewater reuse has increasingly become a sustainable alternative to the efficient use of water as well as the mitigation of the negative environmental impacts generated by the release of the water to the environment in an indiscriminate way. Thus, it is very important to know and evaluate the physiological variables of gas exchanges of plants cultivated with these waters, in order to obtain precise answers their effects on plant physiology. The present study aimed to evaluate the gas exchange of yellow capsicum cultivated in soil fertilized with human urine and cassava wastewater. The experiment was conducted in a protected environment at the Federal University of Campina Grande, Campina Grande -PB. A completely randomized design with eight treatments and five replications was used. The treatments were cattle manure (T1); NPK (T2); human urine treated (T3); cassava wastewater (T4); (T3)+(T4); 2x(T3); 2x(T4); 2x(T3+T4). The volumes of the biofertilizers were defined according to the nitrogen and potassium contents of urine and cassava wastewater, respectively. At 15 and 30 days after transplanting, the variables of gas exchange, the efficient use of water and the instantaneous efficacy of carboxylation were evaluated. The data were submitted to Tukey test at 5% probability. The results indicated that there wasn't statistical difference for efficient use of water (UEA) evaluated at 30 DAT.The treatment 5 provided the best results in relation to gas exchange, for the variables internal concentration of CO 2 (Ci), net assimilation rates of CO 2 (A), stomatal conductance (gs), leaf transpiration (E), higher efficiency of water use (UEA) and instantaneous carboxylation efficiency at 15 DAT, so for 30 DAT the biofertilizer that provided the best results was the T4 treatment, although there weren't significant statistical differences among the treatments for (UEA), except for of T5.
