Rapid change in the environment due to global warming is not only linked with the scarcity of food but with the availability of green fodder also. Thirty mungbean genotypes were evaluated using randomized complete block design for fodder yield across years at two extreme environments of Pakistan; badly affecting by the flood. Broad-sense heritability and selection response were studied for degr...

phenotypic coefficient correlation is a relation criteria for traits. this coefficient can be used to differentiate insignificant traits of  varieties in selection programs. this survey was carried out with 10 breeding populations and susceptible controls in normal and stress conditions. the drought field was irrigated when plants reached wilting point. traits such as leaf length and width, pet...

The study aimed to investigate the effects of mycorrhizal inoculation on growth and development; three plant species: Petunia hybrida, Antirrhinum majus, Dianthus chinensis. as well heavy metals in soil. measured various parameters such shoot fresh weight, root flower numbers, length, diameter, leaves number, petiole length. Results showed a significant increase weight 10.74 g, weight1.77g, num...

Rumex palustris responds to complete submergence with upward movement of the younger petioles. This so-called hyponastic response, in combination with stimulated petiole elongation, brings the leaf blade above the water surface and restores contact with the atmosphere. We made a detailed study of this differential growth process, encompassing the complete range of the known signal transduction ...

Castor, (Ricinus communis L.) is one of the most important commercial, non-edible oilseed crop. Tobacco caterpillar, Spodoptera litura (Noctuidae: Lepidoptera), a major defoliator castor. The biophysical factors in castor play role conferring resistance against S.litura. present study was conducted with an objective, to basis S. litura. Feeding preference larvae leaves IVHT-39 followed by Salem...

Among a French collection of 150 Diaporthe helianthi / Phomopsis helianthi Munt.-Cvet. isolates collected on sunflower since 1995, 4 were chosen for their different characteristics according to their geographic origin and the part of the infected plant where they were sampled (leaf, petiole, capitulum). Phenotypic and molecular characterisation studies were conducted on these isolates. Phenotyp...

A new genus and species of myrmeciine ants, also called bulldog is described illustrated from the Palaeocene Menat (France) as Tyrannomecia inopinata gen. et sp. nov. This taxon represents oldest representative subfamily provides calibration point for total clade Myrmeciinae. It shows apomorphic characters used to define Myrmeciinae: mandibles elongate such that their length three-quarters or m...

salinity stress is one of the most important abiotic stresses which threaten plants. in order to study the effect of salinity stress on yield and yield components of sunflower and also genetic analysis of these traits in relation with salt tolerance, a factorial experiment based on a completely randomized design with three replications was conducted. pots were arranged outside the greenhouse in...

Plants grown under a canopy recognize changes in light quality and modify their growth patterns; this modification is known as shade avoidance syndrome. In leaves, leaf blade expansion is suppressed, whereas petiole elongation is promoted under the shade. However, the mechanisms that control these responses are largely unclear. Here, we demonstrate that both auxin and brassinosteroid (BR) are r...

Abstract The strawberry growth and fruit yield of five Korean cultivars in the tunnel-type greenhouse predicted using their growth. number leaves, petiole length, leaf length width, crown diameter, ratio red far-red (RFR) were measured during cultivation period. leaves all exhibited a similar trend this period; plant ‘Maehyang’ longest, trends except for ‘Jukhyang’, width ‘Arihyang’, was diamet...
