New method for quickly determining fruit point density

Abstract

The invention discloses a new method for quickly determining the fruit point density. The new method comprises the following steps: taking a plastic transparent board or a cardboard of 29 cm*21 cm, reserving an edge of 3-5 cm on each of the upper end, the lower end, the left end and the right end and forming a frame; then drawing a plurality of square small grids of 1 cm*1 cm in the frame; after the completion of drawing, hollowing out the one small grid every other small grid, so that a plurality of empty grooves of 1 cm<2> are formed, and a test template is obtained; during measurement, directly buckling the obtained test template on a fruit, wrapping the whole fruit in the template, respectively counting the number of fruit points on the corresponding empty slot per square centimeter to obtain the number of the fruit points per square centimeter. The new method disclosed by the invention has the benefits that the manipulative ability and the innovation ability of a student are enhanced, and more time is saved; the fruit appearance and the determination of other data are not affected; the determination method is simple and feasible, the template can be repeatedly used for multiple times, the determined data is accurate, and other fruits and vegetables, like applies, peaches and the like can also be determined.

Description

technical field [0001] The invention relates to an experimental method, in particular to a new method for rapidly measuring the fruit point density. Background technique [0002] The fruit point is naturally developed from the stomata on the surface of the fruit. In the process of fruit development, especially in the early stage of fruit growth, the fruit point is an indispensable tissue to control the gas exchange and water loss of the fruit, and to maintain normal respiration and transpiration. When the fruit is ripe, a cork cell layer is formed in the fruit point, which is filled with sclerenchyma cells and becomes a protective organ that only allows gas and water to pass through. The soluble solid content of the pulp in the part with more fruit spots of peach fruit is higher; the fruit with large fruit spots, high density and high coverage value has strong storability, low weight loss rate during storage and good water retention, but the existence of fruit spots is easy...

Problems solved by technology

In the past, we mainly asked students to draw 10 pieces of 1cm on a pear 2 This experiment is carried out with a small grid method. According to this situation, the students' measurement is relatively slow and the workload is heavy, so it is difficult to complete the experiment on time
