As to the importance value index (IVI) calculated at 90 DAS, it is observed that in 2011 the weed species Bowlesia incana, belonging the Apiaceae family, presented the highest value for the treatments with ryegrass (75,01), wild radish
(65,36) and wheat (44,43).
The high accumulation of both types of matter under wild radish
culture is due to the high precocity of this crop; 105 days after seeding, the fresh matter of wild radish
shows a decreasing trend due to the senescence of the oldest leaves.
Despite its success however, little is known about genotypic variation in wild radish
. This study was conducted to determine the genotypic variation between and within populations of wild radish
along environmental gradients and to identify the traits that have contributed to the success of wild radish
in Western Australia.
Foliar herbivory in wild radish
plants resulted in induced biochemical and physical responses, increased [TABULAR DATA FOR TABLE 2 OMITTED] resistance to several herbivores, and increased seed set compared to uninduced control plants.
In two experiments with wild radish
, we found that pollen applied in mixtures from two donors germinated more slowly than identically applied pollen loads that used pollen from only a single donor.
Leaf damage by herbivores affects attractiveness to pollinators in wild radish
, Raphanus raphanistrum.
To provide a continuous display of wild radish
flowers to pollinators, arrays of nonexperimental plants were left at the field site during all times that the experimental arrays were not present.
Male and female fertility variation in wild radish
, a hermaphrodite.
is pollinated by a variety of bees, butterflies, and flies (Kay 1976; Stanton et al.
Effects of pollen donor identity on offspring quality wild radish
, Raphanus sativus.
(Brassicaceae), the wild radish
, is a widespread and common species that occupies coastal plains and cismontaine inland valleys along the Pacific coast of North America from northern Baja California to Washington and is a pantemperate weed elsewhere.
