Generative Phase

Reproductive traits determine the selection method in plant breeding. The benggala grass of the Hamil cultivar was thought to be apomictic; thus, a study was conducted to determine its reproduction. The research began by studying the morphological characters, continued with observing the generative phase and seed production of the cultivar planted from seeds (generative) and from pols (vegetative). The experiment was conducted in the greenhouse of the Research Institute of Animal Production. The experimental design was a completely randomized design with ten replications, and the treatments were different types of plant materials: seeds and pols. The Hamil cultivar taken from RIAP Collection was planted in pots with a diameter of 40 cm and a height of 30 cm. The results showed that most of the morphological characters of the Hamil cultivar planted from seeds and from pols were not different (P >0.05), so it was presumed that they were apomictic. The difference in morphology was only in the length and width of the flag leaves and the length of the internodes, where the cultivars planted using seeds were higher. The production of seeds, pithy seed weight, and seed germination of cultivars planted using seeds were higher (P <0.05). Further research is needed to determine the apomixis properties based on cytologically Hamil cultivars.   Keywords: apomixis, benggala grass, morphology, plnting material; seed

This study aimed to assess the potential use of increasing levels of murumuru cake (Astrocaryum murumuru var. murumuru, M art.) (MC) in sheep diets as a replacement for Mombasa grass (Panicum maximum Jacq). Metabolic tests were performed with 20 castrated male sheep at Embrapa Amazônia Oriental, Belém, Pará, during 26 days. The experiment was arranged in a completely randomized design, with five diets and four replications. MC0: 100% grass; MC10: 10% MC and 90% grass; MC20: 20% MC and 80% grass; MC40: 40% MC and 60% grass; and MC60: 60% MC and 40% grass. The intake and the coefficient of apparent digestibility of dry matter (DMI and CDDM), organic matter (OMI and CDOM), crude protein (CPI and CDCP), neutral detergent fiber (NDFI and CDNDF), acid detergent fiber (ADFI and CDADF), ether extract (EEI and CDEE), cellulose (CELI and CDCEL), hemicellulose (HEMI and CDHEM), and nitrogen balance (NB) of experimental diets were determined. The intake of mineral material (MMI) and lignin (LIGI) were also determined. The DMI, OMI, MMI, CPI, NDFI, and ADFI displayed a decreasing linear effect with the replacement of Mombasa grass by MC in the diet. The EEI and the LIGI presented quadratic effects according to the replacement levels of MC in the diet. The CDDM, CDOM, and CDHEM displayed increasing linear effects, between MC0 and MC60. The CDEE, CDNDF, CDADF, and CDCEL displayed a quadratic effect, with optimum replacement levels of 56.65%, 41%, 31.33%, and 27.46%, respectively. The nitrogen balance presented a negative linear effect in the range of 0% to 60% of murumuru cake. One can conclude that murumuru cake is an alternative to the dietary supplementation of ruminants in replacing the Mombasa grass because it provides an increase in the digestibility of nutrients for sheep. However, a limited replacement level must be implemented, considering that from 27.46%, 31.33%, 41%, and 56.65% replacement, a decline occurs in the CDCEL, CDADF, CDNDF, and CDEE, respectively, although a negative nitrogen balance does not occur.

<p>Green beans are legume plants that are in great demand because of their high nutrition content and include plants that require boron to support growth from the vegetative to generative phase. The study aims to assess the growth and production of green beans due to influence of the dose and time of boron application. The research was carried out using completely randomized design with factorial pattern 3×3 with 3 replications. The first factor was the treatment of boron doses of 1, 1.5, and 2 kg/ha was given once at 7 Day After Planting (DAP), fertilizer application twice at 7 and 28 DAP, and once given at 28 DAP. The results showed that dose of boron at a dose of 1 kg/ha was able to produce the number of affective root nodules and the best pod weight. The treatment of boron once at 7 DAP can increase plant height, flowering age, pod weight, and seed weight per pod. The interaction between dose and time of boron application affects the number of affective root nodules and seed weight per pod.</p>
