| The close relationship between the chlorophyll-meters readings and the total chlorophyll and nitrogen contents in leaves, has allowed their evaluation both in annual and perennial species. Besides, some physiological events such as the CO2 assimilation have also been estimated by chlorophyll meters. This work was carried out aiming to evaluate the gas exchanges of peach palms as a function of the chlorophyll SPAD-Meter readings. Three year-old peach palms from Yurimaguas, Peru were studied in Ubatuba, SP, Brazil, spaced 2 x 1 m in area under a natural gradient of organic matter which allowed four plots to be considered, according to the peach palms leaves colors, from light yellow to dark green. The SPAD readings and the stomatal frequency of leaflets were... |

| O achachairu (Garcinia sp), fruta largamente produzida na Bolívia, vem sendo comercializado no Brasil há vários anos. O fruto é globoso-oblongo, de polpa branca, suculenta e textura mucilaginosa e de sabor doce-acidulado equilibrado (ºBrix 15 e pH 4,1). Devido ao crescente interesse em seu cultivo no Brasil, pesquisaram-se a germinação das sementes e o desenvolvimento das plântulas durante os primeiros 12 meses após sua emergência. As sementes, extraídas de frutos bem maduros, foram postas a germinar em duas situações: 1) ambiente controlado em estufa tipo B.O.D., sob as temperaturas de 25 e 30 ºC, fotoperíodo de 16 horas e irradiância de 32 µmol.m-1.s-1, e 2) ambiente de temperatura não-controlada: 3) B.O.D, cuja temperatura oscilava entre 20 e 30 ºC, e... |

| Cutting propagation was the system to produce quince nursery trees (Cydonia oblonga). Experiments have been carried out in order to identify news propagations methods. As a result of this research, the 'Japonês' quince (Chaenomeles sinensis) was selected with rootstock, due to its good plant vigor for grafting, rusticity, and adequate performance in the field, mainly in the first years after planting. However, the best grafting period and grafting method must be determined for this rootstock. This research evaluated three grafting methods and five quince scion cultivars on 'Japonês' rootstock. The quince cultivars 'Provence', 'Mendoza Inta-37', 'Portugal', 'Smyrna', and 'Japonês' were grafted by winter cleft grafting, winter budding, and summer budding on... |
