Voorbeelden van tuber

• Concentrations increased substantially thereafter to a maximum, about 100 d later, when tubers were said to be mature.

• In such cases seed tubers were dug up and transferred to a cooler place (see next section).

• Farmers were prepared to accept some late blight in tubers if other characteristics were favourable.

• Variation in soil temperatures accounted for 96 and 99 % of the variation in tuber yield at varied population densities and sowing dates, respectively.

• It can be concluded that a population of tubers sorted by minimum diameter will also be sorted by mass according to these relationships and variances.

• At natural maturity, tubers from the whole trial were harvested immediately and weighed to determine tuber yield (kg).

• Fresh tubers can be peeled, chipped, dried and milled into -our.

• Absent from private sector research, not surprisingly, are many crops cultivated by the world's poor, including small-grain cereals, tubers and legumes.

• Although post-harvest losses were slightly reduced after four months of storage by both treatments, this had no effect on tuber yield.

• There was a tendency for borderline tubers to pass along the rollers slightly too far and fall into the size above the correct category.

• In these three cultivars, therefore, tuber initiation started 19+28 d after emergence of the sprout.

• An infested tuber was defined as one with visible tunnelling damage, regardless of the presence or absence of larvae.

• A digital imaging technique was developed to quantify accurately the incidence of internal browning in potato tubers.

• The absence of a direct correlation between trapped adults and tuber infestation in sandy soil may be due to lack of statistical power.
