Both departments said last week in written responses to questions that they were not testing wheat gluten imported from the mainland for the presence of melamine scrap, a residue from the manufacture of a chemical used in plastics production.
They've unearthed a cultural fossil record spanning a century: political buttons, ticket stubs, spelling tests, wheat pennies, flash cards, candy wrappers, and a mummified pet, its species hard to discern.
In the practical testing, wheat was sown as a common main crop before the growing of summer catch crops.
The obtained results showed significant differences among the tested wheat cultivars in the two seasons for number of spikes/m2, spike length, kernels number/spike, kernels weight/spike, weight of 1000 kernels, and grain and straw yields/fad.
One study tested wheat varieties with introduced resistance genes against leaf and stripe rust and reported a 12% reduction of yield [49], which was considered to be a very large effect [50].
The UBQ gene was confirmed to be relatively stable in the tested wheat tissues (data not shown).
Similarly, among the lignocellulosic substrates tested, wheat bran gave maximum yield of xylanase by Cellulosimicrobium sp. as compared to other substrates viz.
The cDNA products of each tissue were normalised using UBQ [AF517839] as the internal reference gene [ 68], which was confirmed to be relatively stable in the tested wheat tissues in our laboratory.
The same was true of plants sampled in the spring of the following (i.e. second) year but in summer, when take-all was severe, symptoms were significantly less severe on plants sampled from plots testing set-aside/conservation covers than on those from plots testing wheat (after wheat or after set-aside/conservation covers in the first year only).
In summer, take-all was more severe than it had been in the preceding year but there were only small, and not significant, differences between plants sampled from plots testing wheat and from those testing set-aside/conservation covers (Table 16).
