Background: Auxin may have a positive effect on plants under drought stress. White clover is widely cultivated and often prone to water shortages. In the present study, we investigated the effects of exogenous indole −3-acetic acid (IAA) on growth and physiological changes of white clover under drought stress condition. The contents. Salt stress initiates relatively smooth changes in gene expression in response to osmotic stress and a more pronounced change in expression of significant numbers of genes related to the ionic. compared to white clover also included lower senescence, higher stolon density, increased root dry weight, and a higher maximum nodal root diameter. Drought decreased the net photosynthetic rate by up to 48% in BC2 and white clover, but there was no significant effect on the BC1 generation. BC1 hybrids were therefore. New Zealand (Accepted 14 February ) Summaryive herbicides commonly used for suppression of weed growth in white clover seed crops were tested for toxicity to white clover (Trifolium repens), the nodule-forming bacteria Rhi:obium irifotii, and the nitrogen-fixing symbiosis of these by:

males were also detected on the roots of clover. The studies on the host-parasite relationships of nematode-feeding sites in white clover roots infected by these nematodes showed a high susceptible response. Meloidogyne hapla and H. daverti infections were also observed on nitrogen-fixing root nodules of white clo-.   Effects of factors associated with soil acidity (low pH, low calcium, high aluminium and high manganese) on theTrifolium repens-Rhizobium trifolii symbiosis were investigted under laboratory conditions using an axenic solution-culture technique. μM manganese increased root elongation in the range pH –, but had no effect on root hair formation, the number of Rhizobium in the rhizosphere, or nodule by:   To increase our insight into the above- and belowground N flows in grass and grass-clover swards relations between crop and soil parameters were studied in a cutting trial with perennial ryegrass (Lolium perenne) monocultures and ryegrass–white clover (Trifolium repens) mixtures.

McNEUR, Ecologist, Grasslands Division, D.S.I.R., Palmerston North. The popular belief among many is that clovers will not grow in acid soils, and for this reason large quantities of lime are often used to make soil less acid in an attempt to increase clover theFile Size: KB.

  Red clover (Trifolium pratense L.) is one of the most important plants in forage production, especially in northern areas. Fertilisation practices are focused on high yield and forage quality but effects of nutrients on nodulation and N 2 fixation are poorly understood. The aim of this work was to study how nitrogen (N) and phosphorus (P) separately as well as in combination affected by: Effects of sludge-borne heavy metals on plant growth, nodulation, and nitrogen (N2) fixation of alfalfa (Medicago sativa L.), white clover (Trifolium repens L.), and red clover (Trifolium pratense.
