The haploids used in breeding programs facilitates the genetic analysis by eliminating the complexity of the heterozygous state. However, this technique has not provided satisfactory results when applied to Citrus and related genera. In the present study, we aimed to refine the protocols for producing calluses in different species of Citrus and one species of Poncirus. The plant material used was collected from the Citrus Germplasm Active Bank of EMBRAPA Cassava & Fruits, and the work was developed in the Tissue Culture Laboratory of this institution. Four culture media were used in the callus induction stage. Each culture medium was considered an isolated factor and applied to each of the eight genotypes studied, totaling 32 experiments. Among the genotypes, different experiments were conducted based on the difference in the size of the floral buds. Only the anthers extracted from the floral buds of the Citrus medica L. genotype responded to the treatments applied in the induction stage. Consequently, only this species was submitted to the callus multiplication stage, in which two experiments were performed with two culture media. The other genotypes are still being investigated to promote future protocol adjustments to allow the continuity of the studies on callus induction. |

The use of green manures (GMs) in combination with nitrogen (N) fertilizer application is a promising practice to improve N fertilizer management in agricultural production systems. The main objective of this study was to evaluate the N use efficiency (NUE) of rice plant, derived from GMs including sunn hemp (Crotalaria juncea L.), millet (Pennisetum glaucum L.) and urea in the greenhouse. The experimental treatments included two GMs (sunn hemp-15N and millet-15N), absence of N organic source (without GM residues in soil) and four N rates, as urea-15N (0, 28.6, 57.2 and 85.8 mg N kg-1). The results showed that both rice grain and straw biomass yields under sunn hemp were greater than that of millet or without the application of GM. The NUE of rice under sunn hemp was greater than that under millet (18.9 and 7.8% under sunn hemp and millet, respectively). The urea N application rates did not affect the fertilizer NUE by rice (53.7%) with or without GMs. The NUE of GMs by rice plants ranged from 14.1% and 16.8% for root and shoot, respectively. The study showed that green manures can play an important role in enhancing soil fertility and N supply to subsequent crops. |
