Influence of media and growth regulators on regeneration and morphological characteristics of strawberry cvs Kurdistan and Merck (Fragaria x ananassa Duch.)

To evaluate the best media and growth regulator combinations for the regeneration and morphological characteristics of strawberry, meristems of Kurdistan and Merck strawberry cultivars were cultured on Murashige and Skoog (1962),  Gamborg et al. (1968) and Nitsch and Nitsch (1969) media supplemented with various growth regulator combinations including B1: (BA 1.0 mg/l + IBA...

Phytotoxicity of Parthenium hysterophorus residues towards growth of three native plant species (Acacia catechu willd, Achyranthes aspera L. and Cassia tora L.) in Himachal Pradesh, India

Parthenium hysterophorus is a strong allelopathic plant which belongs to the family Asteraceae of flowering plants. It is a rapidly spreading invasive plant species in the state of Himachal Pradesh up to 2000 m altitude. The allelochemicals produced by P. hysterophorus showed powerful toxic effects on the growth of other plant species. These allelochemicals are either phytotoxic phenolics or...

Influence of the harvest age on fructan content and fructosyltransferase activity in Agave atrovirens karw pine

The effect of age on the composition and concentration of non-structural carbohydrate was determined in the “pine” or “head” of Agave atrovirens Karw. The influence of plant age on the 1-FFT enzymatic activity, the electrophoretic pattern of proteins and the non-structural carbohydrate yield were also determined to establish the optimum age for harvest. The carbohydrate composition of 6...

Inter correlation between soil properties and growth of Azadirachta indica in various types of plantations of Jodhpur region (Rajasthan, India)

Physico-chemical properties do not vary rapidly for short distance in arid and semiarid regions in absence of plantation or some manual intervention. In case of barren land, it is difficult to enhance soil health and its productivity until and unless a large quantity of fertilizer and irrigation facilities are employed. Application of high dose of fertilisers and insecticides result in short-term increase in production,...
