Twenty-seven weedy rice plants were chosen for genotyping along with 12 accessions of temperate japonica varieties that are cultivated in California. Leaf tissue from the outdoor grown plants was excised and desiccated for shipment to Clemson University for DNA extraction. … Continue reading →

Restriction digestion of the target region-specific PCR product from lines 1, 2, 5 and 11 revealed that lines 1 and 5 were fully resistant to BsrI digestion, whereas line 11 showed partial digestion. However, line 2 showed complete digestion of the … Continue reading →

Recombination was only detected in O. rufipogon, so the longest nonrecombining blocks were only utilized in the comparisons including O. rufipogon. Each comparison was run in M-mode with wide value cutoffs for all parameters to determine where posterior probability distributions ranged. After … Continue reading →

As required for layer stacks, the imagery was resampled to a single scale using cubic convolution. The increase in pixel size brought the grain of the images and that of the field evaluations of vegetation composition to a similar scale, and … Continue reading →

When dealing with fast maturing crops, the grower can prevent weeds from dispersing seeds . Since weeds adapt to continuous use of the same tools, implementations of other integrated management plans are crucial .Using more than one management strategy increases … Continue reading →

The effect of depth on 1,3,-D concentration was most evident in water seals and bare soil plots. HDPE and VIF plots had more uniform distribution of the fumigant through the soil profile than the water seals plots, especially 48 hours after … Continue reading →

If growers are to adopt alternative irrigation systems, understanding potential shifts in weed species’ composition will be critical to weed management. It is well documented that weed community composition can affect yields. The critical period of watergrass competition for rice … Continue reading →

Baker highlighted high competitive ability as a characteristic of invasive species, although his focus was on competition through “special means” such as allelopathy and choking growth . In practice, invasive plant species may coexist with and outcompete natives through a … Continue reading →

These standards have less meaning with the production of a new crop type, and thus create uncertainty and potential for conflict between tenants, landlords, and end-users seeking control over the production process. Landowners may want to ensure the crops or … Continue reading →

Moreover, field men visits can provide a source of information and a familiar contact through which producers could “negotiate contract terms, share technical information, estimate expected yields, and maintain a presence to ensure that the contract will be renewed” The use of field men … Continue reading →
