Cladophora

In the present piece of research work, the effect of SLF prepared with macroalgae Cladophora and Gracilaria spp was studied on Triticum aestivum Linn. in two sets of experiment- 1. Seventy two hrs after germination in petriplates; 2. Eight days after sowing in the plastic pots containing garden soil. Seeds of Triticum aestivum were soaked in 5%, 10%, and 15% SLF solutions and control for duration of 12 hours. Seed germination index, average number of roots, average length of roots and shoots were the parameters recorded in young seedlings post 72 hrs germination. Germination index was 100% in 5% Cladophora and in all strength of Gracilaria as against only 70% in control. Average root and shoot length of 72 hours old seedlings were recorded to be higher in 5% Gracilaria SLF followed by 10% Cladophora SLF treatment. In another set of experiment, germination index, average root and shoot length, fresh weight and total chlorophyll were studied in  8 days old  seedlings  that were cultivated in pots. Comparative analysis indicated that treatment with 5% Gracilaria SLF had a promoting effect on these parameters followed by 5% Cladophora SLF treatment. It is concluded that Seaweed liquid fertilizer of 10% Gracilaria has potential as a biostimulant in early growth of Triticum aestivum.

Studies were carried out in the intertidal reefs of Boa Viagem beach, Recife, northeastern Brazil, in December 2009 (dry season) and April 2010 (rainy season), to analyze the community structure of seaweeds growing on other macroalgae. The material was collected in two areas, each around 30 m long, in different habitats which are suitable for the growth of seaweeds. The seaweeds remained frozen until the analysis. The specimens are deposited at the Herbarium of the Instituto de Botânica, São Paulo, Brazil (SP). Nine species were recorded for the Pernambuco coast for the first time: Boodlea composita (Harv.) F. Brand, Ceramium corniculatum Mont., Chaetomorpha clavata Kütz., C. nodosa Kütz., Chondracanthus cf. saundersii C.W. Schneid. & C.E. Lane, Cladophora laetevirens (Dillwyn) Kütz., Neosiphonia sphaerocarpa (Børgesen) M.-S. Kim & I.K. Lee, Ulva linza L. and U. prolifera O.F. Müll. Of these, four species had their distribution along the Brazilian coast considerably expanded.
