Pesquisa Agropecuária Brasileira , 2000,
Abstract: O trabalho foi conduzido na regi o de Goiania, com o objetivo de avaliar a qualidade fisiológica e sanitária das sementes de sete cultivares precoces de soja (EMGOPA 304, EMGOPA 309, EMGOPA 316, EMBRAPA 1, EMBRAPA 4, Rainha e Itiquira), produzidas em três épocas de semeadura (convencional, em 20/11; antecipada, em 30/10; e retardada, em 30/12/1995). O delineamento experimental foi de blocos casualizados, com três repeti es, em esquema de parcelas subdivididas. A qualidade fisiológica foi avaliada com base na germina o em rolo de papel e em areia e no vigor, pelo teste de tetrazólio, enquanto a sanidade foi avaliada pelo teste do papel de filtro. Os resultados obtidos permitem concluir que: a qualidade fisiológica e sanitária das sementes é influenciada pelas cultivares e épocas de semeadura; a qualidade das sementes produzidas na semeadura antecipada para o final de outubro é afetada por condi es adversas de umidade, danos mecanicos e incidência de patógenos, especialmente Phomopsis sojae, enquanto na semeadura retardada para o final de dezembro é afetada por danos mecanicos.

Abstract: This experimental study aimed to evaluate the effects of doses of controlled-release fertilizer (ALL) on the development of rubber tree rootstocks. The fertilizer used was Osmocote , scheduled to be released for 8-9 months and with the following composition: N (15%), P2O5 (9%), K2O (12%), Mg (1%), S (2.3%), B (0.02%), Cu (0.05%), Fe (1%), Mn (0.06%), Mo (0.02%) and Zn (0.05%). A randomized block design was used, with four treatments and eight replicates of 20 plants per plot. The controlled-release fertilizer was added to Rendimax Floreira substrate at doses of 0, 3, 6 and 9 g per liter, and rootstocks were produced in plastic containers with a capacity of two liters of substrate. Three seeds of clone GT 1 were scattered in each container and thinning was performed on day 60, leaving the most vigorous plant only. After the fourth leaf shot from each rootstock, the containers of each treatment were topped, due to compaction, with 300 mL of the relevant fertilizer and substrate mixture. The rootstocks were evaluated at eight months of age as to height, stem diameter (DC) 5 cm above root collar, total dry matter, shoot and root dry matter, leaf nutrient levels and percentage of plants suitable for grafting (DC≥1.0 cm). Results revealed that adequate development and nutrition of rootstocks was achieved by using 6 g of controlled-release fertilizer per liter of substrate.

Abstract: Os ensaios foram instalados em casa de vegeta o na Embrapa Cerrados, Planaltina-DF, em agosto de 1999. Nos primeiros 30 dias, estacas da cultivar MSC (Marília Sele o Cerrados) foram mantidas sob nebuliza o com duas regas diárias. Avaliaram-se os seguintes parametros: percentagens de estacas brotadas, enraizadas, com fungos, peso de matéria fresca e seca da parte aérea e das raízes, aos 90 dias após o plantio. O estudo foi composto de dois experimentos. No primeiro, utilizaram-se estacas coletadas em agosto de 1999, e oito tipos de substratos. O Plantmax Florestal Estacaò proporcionou maior brota o e enraizamento, e ainda menorincidência de estacas contaminadas por Colletotrichum gloeosporioides, comparativamente ao substrato à base de Plantmax Hortali as.ò O aditivo Nutriplantaò quando combinado com o fertilizante Osmocoteò, no substrato à base de Plantmax Florestal Estacaò, proporcionou maior brota o e enraizamento e também menor incidência de estacas contaminadas com C. gloeosporioides. No segundo ensaio, utilizaram-se estacas do híbrido RC1 ((F1: Marília x Roxo Australiano) x Marília), coletadas em agosto de 2000, tratadas com 2.000 ppm de AIB, plantadas em bandejas de poliestireno expandido com doze tipos de substratos. Para enraizamento das estacas do Híbrido RC1, n o houve diferen a entre os substratos testados. A adi o de um g de Osmocote por estaca, aos 30 dias após o plantio no substrato Plantmax Florestal Estaca , proporcionou o melhor desenvolvimento da parte aérea das estacas do Híbrido RC1.

Abstract: the soil born diseases cause expressive losses in passion fruit crops in brazil. the use of resistant rootstocks is an alternative to control these diseases. several wild species of passifloraceae have presented resistance to soil born pathogens, but their utilization as rootstock from seeds has been limited mainly by differences of thickness between the rootstock and the graft of the commercial cultivars. these limitations could be reduced using herbaceous cuttings as rootstock. in these experiments, herbaceous cuttings has been collected from passiflora setacea (source ec-ps 1), p. nitida (source ec-pn 1), p. caerulea (source ec-pc 1), p. actinia (source ec-pa 1) and a f1 hybrid between p. setacea x p. edulis f. flavicarpa (commercial cultivars) and treated with acetic naphthalene acid (ana) at 500 mg/l and kept in moisture greenhouse. the graftings (lateral grafting) were made at 40, 55 and 70 days after the collecting and planting of the cuttings. the evaluations were made at 145 and 150 days after the cutting planting determining the percentages of living grafts and sprouting grafts and length of the sprout graft. the grafting on rooted-herbaceous cutting of p. nitida and f1 hybrid was technically viable for passion fruit-seedling production.

Abstract: This study evaluated the initial growth and the establishment potential of twelve hevea clones cultivated in Paracatu,Minas Gerais State. Randomized blocks were used in a scheme of subdivided parcels with four repetitions; the parcels were composedby 12 hevea clones (Hevea brasiliensis Müell Arg.) (PB 235, PR 255, IAN 3193, IAN 3087, IAN 3156, IAN 2880, RRIM 600, RRIM701, PR 107, IAC 15, IPA 1 and GT 1), planted in a 10 x 2 m spacing. The sub parcels represented the four annual evaluations. Theplant survival, the stem circumference and plant height were evaluated until five years old. The data were submitted to analysis ofvariance and average tested through Scott-Knott with 5% of probability. Hevea clones presented different establishment potential inthe studied region. The clones RRIM 600, GT 1, IAC 15, LCB 510 and IAN 2880 presented 100% survival rates but they did notpresented differences between the stem circumference and height of the tree at five years old.
