The composition of hydro-distilled essential oils of Phlomis anisodonta Boiss. subsp. occidentalis Jamzad in vegetative, flowering and post flowering stages were investigated using GC and GC-MS, leading to identification of 41, 26 and 23 compounds, respectively. In all three samples, sesquiterpenes were the main components. In vegetative stage the main components of the oil were germacrene-D (1...

Numerous species of insect pests attack cotton plants, out of which the cotton boll weevil (Anthonomus grandis) is the main insect in Brazil and must be controlled to avert large economic losses. Like other insect pests, A. grandis secretes a high level of α-amylases in the midgut lumen, which are required for digestion of carbohydrates. Thus, α-amylase inhibitors (α-AIs) represent a powerful t...

Phloem-mobile signals that are regulated by day length activate both flowering and tuber formation. Both signaling processes have numerous elements in common. In this review, FLOWERING LOCUS T and the three signals currently implicated in controlling tuberization, SP6A, miR172, and the StBEL5 complex, are discussed with a focus on their functional roles, their mechanisms of long-distance transp...

Cotton is the main economic crop in China and important owing to its use as an industrial raw material a cash crop. This experiment was conducted cotton-producing area of Xinjiang, China. A hyperspectrometer used monitor canopy spectral reflectance cotton at different stages growth. The results showed that leaf index (LAI) increased with increase amount nitrogen fertilizer added during early fu...

The most important effect of water stress on plants is that it reduces leaf area and leads to changes in morphology. Decreased results crop yield through the reduction photosynthesis. This study investigates effects decrease seed cotton yield, evapotranspiration (ET), use efficiency (WUE), geometry under different growth periods. plant was divided into three periods (vegetative period (VP), flo...

LFYgene plays important roles in determining plant flowering mainly by controlling the timing of phase transition. Constitutive under-expression of LFY gene in Arabidopsis resulted in the formation of late flowering and highly branching phenotype. In this paper, we investigated some physiological and biochemical properties of the transformantsthat were down-regulated LFY gene expression to dela...

We tested the hypothesis that intensity and duration of Macrosiphum euphorbiae infestations in tomato depend on both age (phenological stage) host plant initial number aphids present colony. compared effects three levels infestation two phenological stages (pre-flowering flowering stages) curves. The position peak over time was significantly affected by phase. Populations M. reached highest abu...

The global demand for cotton makes sustainable production an important issue that can be improved by a better understanding of the influence soil microbes on growth. We collected field soils at seedling and flowering/boll-setting (FBS) stages in order to obtain properties growth indices. Bacterial fungal community compositions were assessed high-throughput sequencing 16S rRNA internal transcrib...

Moisture is a significant component in cotton growth and yield, but stress the main factor limiting crop productivity since it has negative impact on cotton's ability to produce high-quality fiber as well square/boll lint output. Reduced water availability during development of bolls could lead drastically decreased yield. Four genotypes (MNH-1020, FH-114, BH-178 CIM-602) were grown under regul...
