The fungus Agaricus bisporus is commercially grown for the production of edible mushrooms. This cultivation occurs on compost, but not all of this substrate is consumed by the fungus. To determine why certain fractions remain unused, carbohydrate degrading enzymes, water-extracted from mushroom-grown compost at different stages of mycelium growth and fruiting body formation, were analyzed for t...
Background and Objectives: Beta-carotene was prepared from Azolla by Lejeune et al. (2000). Beta carotene production from Azolla filiculoides in the Anzali wetland has not been investigated in Iran so far. The present project was aimed at determining the content, quality, and purity of β-carotene extracted from Azolla filiculoides in the Anzali Wetland, and comparing it with synthetic β-caroten...
Floating ferns of the genus Azolla detach their roots under stress conditions, a unique adaptive response termed rapid root abscission. We found that Azolla pinnata plants exhibited dose-dependent rapid root abscission in response to the polyamines spermidine and spermine after a substantial time lag (>20 min). The duration of the time lag decreased in response to high pH and high temperature w...
The effect of successive applications of urban compost (up te 150 and 400 t ha-1 during eight years) en the status ef phosphorus in a calcareous soíl (20%) was testad in a greenhouse experimento An 6-15-15 complex fertiliser was also applied for comparison. Five years of ryegrass and three of horticultural plants (tomate and eggplant) were successively cropped during the experimento Increases o...

Penelitian ini bertujuan mengetahui tumbuh dari jenis IRRI, pupuk NPK, kandang ayam, kambing, sapi pada pertumbuhan mycropylla pinnata, pH , Kandungan C-Organik Kadar N microphylla pinnata. menggunakan...
Much of science progresses within the tight boundaries of what is often seen as a "black box". Though familiar to funding agencies, researchers and the academic journals they publish in, it is an entity that outsiders rarely get to peek into. Crowdfunding is a novel means that allows the public to participate in, as well as to support and witness advancements in science. Here we describe our re...
Ferns are the only major lineage of vascular plants not represented by a sequenced nuclear genome. This lack of genome sequence information significantly impedes our ability to understand and reconstruct genome evolution not only in ferns, but across all land plants. Azolla and Ceratopteris are ideal and complementary candidates to be the first ferns to have their nuclear genomes sequenced. The...
Rice farming in coastal areas is often victim to flooding as a result of climate change. Low-cost adaptation strategies are required increase resilience and rice productivity these flood-prone areas. In this study, enriched Azolla extract (EAE) liquid biofertilizers, combined with selected stress-tolerant varieties, were tested farmers’ fields Pangandaran, West Java from June October 2020. This...
A simple, rapid and eco-friendly method has long been needed for evaluating the compost stability because application of unstable compost in agricultural field causes phytotoxicity. Thus, the CIELAB variables L*, a*, b*, a* x b*, a* / b*, 2000a* / (L* x b*), 1000a* / (L* + b*), chroma (C*ab), hue (hab) and color difference (∆E00) in dried (70oC) and ground composting materials (particle size ≤ ...
