| ABSTRACT: The objective of this study was to determine the leaf tissue flows in Italian ryegrass (Lolium multiflorum Lam.), in different phenological stages, grazed by lambs, and managed under three herbage allowances (6, 9 and 12 kg DM/100 kg body weight under rotational stocking method. The experimental design was completely randomized, with repeated measures arrangement. Forage allowances determined similar growth and intake flows, actual and potential utilization efficiencies of grass and they were different in the phenological stages of Italian ryegrass. The intake of leaf blade, as a percentage of body weight, was higher in the 12% herbage allowance. Considering leaf tissue flows, Italian ryegrass can be managed in forage allowances that vary between... |

| ABSTRACT Using saline water in the agricultural activity has become a reality in several regions of the world. Due to the increase in the demand for fresh water, it is necessary to use cultivation strategies and genotypes tolerant to saline stress to make the production viable. In this context, effects of irrigation management strategies with low-salinity water (0.8 dS m-1) and high-salinity water (9.0 dS m-1) were evaluated, varying the phenological stages of the plants, on the growth and fiber quality of colored cotton. Three cotton cultivars submitted to seven irrigation management strategies were used, constituting a 3 x 7 factorial scheme, in a randomized block design with three replicates, in plots and in protected environment. Saline water... |

| ABSTRACT We evaluated the influence of host preference, mating, and release density on Telenomus remus (Nixon, 1937) (Hymenoptera: Platygastridae) parasitizing eggs of Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae). First, we tested host preference of T. remus (free choice test) offered a choice between eggs of Corcyra cephalonica (Stainton, 1865) (Lepidoptera: Pyralidae) and S. frugiperda. Parasitism capacity and host preference (S. frugiperda) of T. remus reared on either of the two hosts did not differ. Secondly, we evaluated the influence of mating behavior of T. remus females on its parasitism. Only the offspring sex ratio differed between treatments, indicating that the species reproduces by parthenogenesis of the arrhenotoky type.... |

| Abstract: The objective of this work was to evaluate the phenological characteristics and yield of 'Vênus' grapevine (Vitis labrusca) grafted onto different rootstocks, as well the physicochemical traits of its grapes during the 2013, 2014, and 2015 crop seasons. The evaluated rootstocks were 'IAC 766', 'IAC 572', 'IAC 313' and 'IAC 571-6'. The length of the main phenological stages of the grapevine and its thermal demands were assessed during two growing seasons and expressed as days after pruning and degree-day sum, respectively. Grapevine yield and berry physicochemical characteristics were assessed during three crop seasons. 'Vênus' phenological cycle and thermal demands, as well as the chemical characteristics of its grapes, varied with the climate... |

| Abstract The grapevine phenology is dependent on several factors, such as genetics, soil characteristics, climate conditions, pests and diseases and vineyard cultural practices. Among these, grafting may have an effect on the scion behavior due to the influence of the rootstock. Therefore, an experiment was carried out for two years to determine the effect of rootstocks on Cabernet Sauvignon (CS) grapevine phenology, chilling and heat requirements. Treatments consisted of vines grafted on the rootstocks Rupestris du Lot, 101-14 Mgt, 3309 C, 420A Mgt, 5BB K, 161-49 C, SO4, Solferino, 1103 P, 99 R, 110 R, Gravesac, Fercal, Dogridge and Isabel. Budbreak and flowering of the vines, veraison and maturity of the grapes were the phenological stages evaluated,... |
