1. CYTOKININ AND AUXIN INFLUENCE ON GROWTH AND QUALITY OF WATERMELON IRRIGATED WITH SALINE WATER
RESUMO A melancia apresenta grande relevância econômica, no entanto, fatores edafoclimáticos e manejo inadequado vem favorecendo a salinização da água utilizada para irrigação, sendo este um fator limitante para o crescimento e produção da cultura. Contudo, considera-se que a utilização de reguladores de crescimento pertencentes ao grupo das cito

2. Exogenous gibberellin and cytokinin in a novel system for in vitro germination and development of African iris (Dietes bicolor)
ABSTRACT The availability of reliable and reproducible micropropagation systems is a decisive step to successfully propagate plant species with slow growth and low germination rate. The effect was investigated of gibberellin (GA) and cytokinin (CK) in the in vitro germination and development of Dietes bicolor (Steud.) Sweet ex Klatt. Seeds were inoculated in

3. Physalis angulata L. propagation in vitro
ABSTRACT Physalis angulata L. is a plant with great fruit production potential, mainly in family farms, due to its versatility and valuable products such as jellies and juice concentrates. The aim of the present study is to evaluate the effect of two cytokines - i.e., plant growth regulators 6- benzylaminopurine (BAP) and kinetin (KIN) -, in association, or

4. Mitigation of drought stress effects on soybean gas exchanges induced by Azospirillum brasilense and plant regulators
RESUMO O déficit hídrico é limitante à produção agrícola, tendo como efeito primário a redução nas trocas gasosas vegetais, e a continuidade da incidência resulta em menor produtividade. Objetivou-se avaliar as respostas fotossintéticas e a produção de soja sob déficit hídrico severo induzido, em relação à inoculação via semente e aplica

5. Micropropagation of Physalis peruviana L.
RESUMO Physalis peruviana L. (Solanaceae) é uma frutífera herbácea, que vem se consolidando no mercado em virtude de suas potencialidades nutricionais e medicinais. As limitações à sua produção são o ciclo reprodutivo curto, o acometimento dos frutos por pragas e a carência de estudos, o que justifica a busca de estratégias para a sua propagação

6. In vitro culture and acclimatization of Cattleya xanthina (Orchidaceae), an endangered orchid of the Brazilian Atlantic Rainforest
Resumo Cattleya xanthina é uma orquídea neotropical endêmica da Mata Atlântica brasileira, com alto risco de extinção. Neste trabalho analisamos diferentes meios de cultura sobre o desenvolvimento de C. xanthina, e seu status de nitrogênio endógeno. Meios de cultura estudados: Knudson C (KC), Vacin & Went (VW) e Murashige & Skoog (MS), e o meio MS co

7. Interaction between thidiazuron and Azospirillum brasilense on yield characteristics and productivity of rice
RESUMO No arroz, o uso da bactéria Azospirillum brasilense tem se mostrado de grande utilidade para a cultura, podendo incrementar a produtividade final da mesma ou ainda, reduzir a necessidade de nitrogênio em cobertura. Recentemente notou-se que há outros reguladores que desempenham outras funções, como o thidiazuron (TDZ), uma substância de efeito c

8. In vitro multiplication of Eucalyptus hybrid via temporary immersion bioreactor: culture media and cytokinin effects
Abstract This study aimed to assess the influence of culture medium and cytokinin type on in vitro multiplication of an Eucalyptus grandis x E. urophylla hybrid clone via temporary immersion bioreactor (TIB®). JADS, modified MS at a (NO3ˉ):(NH +) ratio, and WPM were used as liquid media; and 6-benzilaminopurine (BAP), kinetin (KIN), and thidiazuron (TDZ) w

10. Cytokinin Dehydrogenase activity in primary roots and characterization of primary metabolites from leaves and rootlets of Ricinus Communis
The aim of this study was to determine the activity of cytokinin dehydrogenase (CKX) and to measure other biochemical components in the primary leaves and radicles of castor seedlings (BRS Energia) in the initial phase of growth. The crude protein extract obtained after a 1-h extraction from the root tissues of seedlings showed no detectable CKX enzymatic ac

11. Citral accumulation in Cymbopogon citratus plant as influenced by N6-benzylaminopurine and light intensity
Cymbopogon citratus (lemongrass) is an aromatic species whose essential oil is rich in citral, with industrial applications due to its lemon scent. The effects of environmental factors on the percentage and composition of essential oils are the main challenges in commercial cultivation. Various studies have indicated the positive effect of cytokinin on terpe

12. Micropropagation of an elite F1 watermelon (Citrullus lanatus) hybrid from the shoot tip of field grown plants
The aim of this work was to develop a protocol for rapid micropropagation of an elite F1 hybrid watermelon cultivar using shoot tip of field-grown plants. Maximum frequency (73%) of shoot tip showed growth response in MS medium supplemented with 5 mg l-1 benzyl adenine (BA) and 0.1 mg l-1 indole-3 acetic acid (IAA). Upon transfer to cytokinin-enriched medium
