Advances in propagation of Ficus carica L. Rev. Bras. Frutic.
Boliani,Aparecida Conceição; Ferreira,Antonio Flávio Arruda; Monteiro,Laís Naiara Honorato; Silva,Marcela Sant’anna Cordeiro da; Rombola,Adamo Domenico.
Abstract Fig tree (Ficus carica L.) stands out due to its range of cultivation and easy adaptation to diverse edaphoclimatic conditions. In addition to its adaptability, fruits have nutraceutical characteristics and are used in industry and for fresh consumption, widely appreciated by the world cuisine. Due to lack of manpower and phytosanitary problems, the area planted in Brazil has decreased recently. To overcome these obstacles, the production of quality seedlings is the first step to obtaining productive and healthy orchards. Therefore, the aim of the present literature review was to gather data referring to advances in research related to the fig tree propagation. Currently, the methods found for fig tree propagation consist of seedling production,...

Do polyembryonic seeds of Carapa surinamensis (Meliaceae) have advantages for seedling development? Acta Amazonica
FERREIRA,Débora Najara de SOUZA; CAMARGO,José Luís Campana; FERRAZ,Isolde Dorothea Kossmann.
ABSTRACT Polyembryony is the differentiation and development of multiple embryos in a single seed. This characteristic can provide advantages, as more than one embryo is produced with the same amount of resources, and the probability of establishment of at least one seedling increases. However, sibling seedlings may also increase competition, affecting development and survival. In the present study, the possible advantages and disadvantages of polyembryony were analyzed in the initial establishment of seedlings of Carapa surinamensis (Meliaceae), a tree species that produces monoembryonic or polyembryonic seeds. In this regard, the development of single seedlings was compared with a pair of seedlings emerging from polyembryonic seeds. We compared the...

Cavalcante,Lourival F.; Cavalcante,Ítalo H. L.; Pereira,Kátia S. N.; Oliveira,Francisco A. de; Gondim,Saulo C.; Araújo,Fernanda A. R. de.
The present study was carried in order to evaluate the effect of saline water irrigation with electrical conductivity (ECw) of 0.5; 1.5; 3.0; 4.5 and 6.0 dS m-1, on germination and some growth variables during the seedling formation process of four guava cultivars (Psidium guajava L.): Pentecoste, Paluma, Surubim and IPA B-38. Water salinity inhibited the germination process, plant height, stem diameter, leaf area and dry matter production of roots, stems and leaves, independently of cultivar. After germination, the seedlings did not survive due to saline water effects of ECw 4.5 and 6.0 dS m-1. After 180 days of sowing, the seedlings irrigated with ECw more than 1.5 dS m-1 did not present agronomic quality for planting. Dry matter production sequence of...

Growth regulator AIB in rooting cuttings of Sapium glandulatum (Vell.) Pax PFB - Pesquisa Florestal Brasileira
Mori da Cunha, Ana Catarina Monteiro Carvalho; Wendling, Ivar; Souza Júnior, Levi.
The present work aimed to evaluate the influence of different concentrations of indolbutiric acid (0, 2000, 4000, 6000 and 8000 mg L-1) in the rooting of cuttings and vigor of the produced seedlings of Sapium glandulatum. The results obtained with relationship to the rooting indicated the best results for the dose of 6000 mg L-1 of AIB, with average of 52%, demonstrating this to be the most suitable concentration for the production of seedlings of this species. It was concluded that rooting cuttings technique of Sapium glandulatum is technically viable and could be used in the production of seedlings, thus overcoming problems of shortage of seeds and low germination rate. Also, it could be an alternative for production of seedlings all the year.
