2. Teste de alelismo entre os mutantes de amadurecimento alcobaça e non-ripening em tomateiro
Desde o início da década de 1980, são relatadas na literatura divergências quanto às relações de alelismo ou não entre os mutantes de amadurecimento de frutos de tomateiro denominados alc (= alcobaça) e nor (=non-ripening). Para dirimir tais dúvidas, foi realizado um teste de alelismo entre os genes considerados. Foram avaliadas 364 plantas F2 prov

3. Produção, qualidade e conservação de tomates heterozigotos nos locos alcobaça, nonripening e ripening inhibitor
O objetivo deste trabalho foi avaliar os atributos de produtividade, qualidade e conservação pós-colheita de tomates, para comparar os efeitos promovidos pelos alelos alcobaça (norª), nonripening (nor) e ripening inhibitor (rin) em heterozigose, isoladamente ou em duplas combinações, sobre frutos de tomateiros híbridos. Foram avaliados dez tratamento

4. Estudos genÃtico/fisiolÃgicos dos mutantes alcobaÃa (alc), non ripening (nor), e ripening inhibitor (rin) em tomateiro / Genetic-Physiological studies of the tomato mutants alcobaÃa (alc), non-ripening (nor) e ripening-inhibitor (rin).
The tomato mutants alcobaÃa (alc), non-ripening (nor) and ripening-inhibitor (rin) were compared for their post-harvest effects as homozygotes, as heterozygotes and in their double heterozygous combinations. The genotypes Flora-Dade, TOM-559 (alc/alc), TOM-613 (nor/nor), TOM-614 (rin/rin), F1 [(Flora-Dade x TOM-613)] (nor+/nor), F1 [(Flora-Dade x TOM-559)]

5. Water Permeability during Tomato Fruit Development in Normal and rin Nonripening Mutant 1
This work tested one aspect of the relations between membrane permeability and fruit ripening. Membrane permeability was measured as [3H]water efflux rate from preloaded fruit pericarp disks. Different stages of fruit development were compared between two tomato (Lycopersicon esculentum Mill) strains: the normal Rutgers and the isogenic nonripening rin strai

6. Autoinhibition of Ethylene Formation in Nonripening Stages of the Fruit of Sycomore Fig (Ficus sycomorus L.)
Differences in the mechanism of ethylene emanation of Ficus sycomorus L. during various stages of the fruit development were investigated by enclosing the figs in jars. Two distinct patterns of ethylene emanation were found. Pattern a. in stages not capable of ripening, neither spontaneously nor as a result of physiological treatment (nonripening stages A an

7. Effect of Sodium Chloride on Fruit Ripening of the Nonripening Tomato Mutants nor and rin1
Tomato (Lycopersicon esculentum Mill) plants of the nonripening mutant nor, the ripening-inhibited mutant rin, and the normal cultivar `Rutgers' were grown in nutrient solution supplemented with 3 grams per liter NaCl from the time of anthesis. In plants treated with NaCl, all the ripening parameters of the fruits of the nor mutant increased, but those of th

8. Effect of the Colorless non-ripening Mutation on Cell Wall Biochemistry and Gene Expression during Tomato Fruit Development and Ripening1[w]
The Colorless non-ripening (Cnr) mutation in tomato (Solanum lycopersicum) results in mature fruits with colorless pericarp tissue showing an excessive loss of cell adhesion (A.J. Thompson, M. Tor, C.S. Barry, J. Vrebalov, C. Orfila, M.C. Jarvis, J.J. Giovannoni, D. Grierson, G.B. Seymour [1999] Plant Physiol 120: 383–390). This pleiotropic mutation is an

9. Comparison of Propylene-induced Responses of Immature Fruit of Normal and rin Mutant Tomatoes 12
Continuous application of propylene to 40 to 80% mature fruits of normal tomato strains (Lycopersicon esculentum Mill.) advanced ripening in fruits of all ages by at least 50%. Although preclimacteric respiration was stimulated by propylene treatment, there was no concomitant increase in ethylene production. Once ripening commenced, the rates of endogenous e

10. Ethylene Production and Respiration in Aging Leaf Segments and in Disks of Fruit Tissue of Normal and Mutant Tomatoes 1
Leaf segments of tomato plants (Lycopersicon esculentum Mill.) of a normal strain and of two nonripening mutants rin and nor were aged in darkness. Respiration in leaf segments of all strains followed a climacteric-like pattern which was accompanied by a similar pattern of ethylene production. l-Methionine-U-14C vacuum-infiltrated into leaf segments at the b

11. Polygalacturonase and Cellulase Enzymes in the Normal Rutgers and Mutant rin Tomato Fruits and Their Relationship to the Respiratory Climacteric 1
Cell wall enzymes at different stages of fruit development were compared between the normal Rutgers and the isogenic nonripening rin tomato. In Rutgers, a detectable increase in polygalacturonase (PG) activity was observed 6 days prior to the respiratory climacteric (43 days postanthesis). The maximum increase in PG activity occurred after C2H2 and CO2 produ

12. Altered Middle Lamella Homogalacturonan and Disrupted Deposition of (1→5)-α-l-Arabinan in the Pericarp of Cnr, a Ripening Mutant of Tomato1
Cnr (colorless non-ripening) is a pleiotropic tomato (Lycopersicon esculentum) fruit ripening mutant with altered tissue properties including weaker cell-to-cell contacts in the pericarp (A.J. Thompson, M. Tor, C.S. Barry, J. Vrebalov, C. Orfila, M.C. Jarvis, J.J. Giovannoni, D. Grierson, G.B. Seymour [1999] Plant Physiol 120: 383–390). Whereas the genetic
