No ano agríco la de 1978/79 instalou-se um ensaio na área experimental da Escola Superior de Agricultura "Luiz de Queiroz", USP, em Piracicaba, SP, tendo por objetivo estudar os efeitos de reguladores vegetais, em diferentes doses e épocas de aplicação, sobre a cultura do algodoeiro (Gossypium hirsutum L. ). Os tratamentos utilizados foram: cloreto de mepiquat (DPC) nas concentrações de 84, 167 e 250ppm, cloreto de clorocolina (CCC) nas dosagens de 250, 380 e 450ppm e ethephon (CEPA) nas concentrações 1670, 3340 e 6880ppm, sendo cada substância aplicada 51, 65 e 143 dias após a germinação, respectivamente. CCC e DPC tornaram mais compacta a arquitetura das plantas de algodoeiro, assim como promoveram reduções nos parâmetros da análise de crescimento. O...

(Note on the germination of Vochysia tucanorum seeds treated with growth regulators). The aim of this work was to evaluate the germination response of Vochysia tucanorum Mart. seeds treated with GA3 and CEPA and germinated under white light or darkness. Newly collected seeds from a Cerrado area were stored for 14 days at two temperatures (25 °C ± 2 and 7 °C ± 1). After the storage period the seeds were pre-treated with distilled water (control), gibberellic acid (GA3), 2-chloroethylphosphonic acid (CEPA) and a mixture of GA3 + CEPA. Following this, the seeds were sown in Petri dishes on filter paper moistened with distilled water and germinated in either darkness or white light. The results suggest that seeds are non-photoblastic and non-dormant, however a...

This study aimed to investigate the effects of growth regulators on germination rates and biochemical compound concentrations in Carica papaya L. seeds (‘Formosa’ group). The seeds were harvested from fruits at maturation stages 3 and 5 (50 and 75% yellow fruit skin, respectively). The effects of 2-chloroethylphosphonic acid (CEPA), KNO3 and gibberellic acid (GA3)on seed germination, germination index speed, soluble sugars, starch, lipids, soluble proteins and total proteins of the papaya seeds were evaluated. The seeds from stage 5 showed a higher rate of germination 30 days after sowing than did the seeds from stage 3. Treatment with CEPA decreased seed germination, apparently due to decreased starch mobilization; the opposite response was observed...
