Allelopathic effect of apricot (Prunus armeniaca L.) root on some crops and weeds was investigated in two independent experiments. First, the effect of concentrations aqueous extract of apricot root (AAR) was assayed on the seed germination of Cicer arietinum L., Phaseolus vulgaris L., Triticum aestivum L., Zea mays L., Amaranthus retroflexus L., Secale cereal L., and Avena ludoviciana Durieu. ...

Cytological analysis of microsporogenesis in 72 popcorn plants, comprising nine from the original population (CMS-43, S(0)) and 63 from seven cycles of self-fertilization (S(1) to S(7)), one plant of S(0) generation (plant 2) was identified with B chromosomes. The number of B chromosomes varied from two to three in the same anther. The pattern of chromosome pairing and meiotic behavior of Bs we...

Remotely sensing the water status of plant canopies remains a long term goal of remote sensing research. Established approaches involve measurements in the thermal infrared and the 900-2000nm reflective infrared. Less popular UVvisible-NIR techniques presumably deserve research attention, because photochemical changes linked to plant water status manifest spectral light scattering and absorptio...

Growth responses of Zea mays and Glycine max to colonization by mixture of combination of three species of arbuscular mycorrhizal (AM) fungi, two species of Glomus and a species of Scutellospora were compared. In Zea mays, plants inoculated with single species of AM fungi showed significantly higher in dry weight than non-mycorrhizal plant for all three AM fungal species. Also, growth of plants...

A survey of plant parasitic nematodes associated with Zea mays in Kashmir valley was conducted from June 2006 to November 2006 which yielded a number of Tylenchids. Among them, the species Tylenchorhynchus zeae Sethi and G. Swarp, 1968, Pratylenchus sativus kaul, 1985, Aphelenchoides srinagrensisKaul, 1985 are reported herein, with dimensions. The parasites are being recorded for the first time...
