Greenhouse experiment was conducted for four months using Leucaena leucocephala and Pleurotus tuber-regium to determine their bioremediation potentials. Leucaena leucocephala, Pleurotus tuber-regium and Leucaena leucocephala combined with Pleurotus tuber-regium were tested for their ability to improve nutrient (N, P, K, total organic carbon) and reduce heavy metals (Zn, Ni, Pb, Cu) of soil poll...

Apios americana is a wild legume-bearing plant with edible tubers. Domestication of Apios is in progress because of the superior nutritional value and health benefits of the tuber. Objectives of this study were to: (1) characterize physicochemical properties of the Apios tuber starch; and (2) understand differences in starch structures and properties between the mother (seed) and child (progeny...

In this study, the interaction between iron and copper on growth parameters (plant height, fresh weight of roots, stem’s length, fresh weight of shoots, fresh and dry weight of seeds), total proteins and the antioxidant enzymes activity   in Cuminum cyminum L.  were investigated. This experiment was carried out in completely randomized blocks with 9 treatments in 3 repetitions.  Plants were tre...

North American isolates of Colletotrichum coccodes, representing six vegetative compatibility groups (NA-VCG), were used to study morphological and pathogenic variability. The objective was to determine if variability in conidial and microsclerotial size was related to pathogenicity. Significant differences were detected in length, width, and length/width ratios of conidia as well as in the len...

Comparisons of photosynthetic rates were made on leaves of ten species of woody dicotyledons grown in the field under full sun or under a canopy which transmitted approximately 18% of full light. Photosynthesis and dark respiration were measured and compared on various bases: area, chlorophyll, fresh weight of lamina, density thickness (fresh weight per unit area), and protein.Light-saturated p...

Tuber pseudoexcavatum, Tuber sinoaestivum, and Tuber indicum are the 3 most important truffles growing in southeast China; however, their cultivation is still inefficient owing to the lack of understanding regarding the composition and function of the bacterial and fungal communities from the soils around the fruit bodies and the ectomycorrhiza of these truffles. The aim of this study was to di...

Potato tuber development has proven to be a valuable model system for studying underground sink organ formation. Research on this topic has led to the identification of many genes involved in this complex process and has aided in the unravelling of the mechanisms underlying starch synthesis. However, less attention has been paid to the biochemical pathways of other important metabolites or to t...

Shallot is one of the tuber crops used in human life worldwide. Lembah Palu variety shallot (LPVS) best raw material for fried industry. The main problem that tubers have no standard harvest age and storage duration to support these plants' germination early growth. Therefore, shallots' growth productivity are influenced by tubers' viability vigor. This study aimed investigate give vigor tubers...

abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...
