Pineapple Fruit

In mainland China, more than 80% of pineapples (Ananas comosus L.) grown are the cultivar ‘Comte de Paris’. Fruit size is an important commercial trait in crops such as pineapple and it is generally believed that cell number and cell size play an important role during fruit size regulation; however, few cellular biological studies on pineapple fruit development have been conducted. To better understand the regulation of pineapple fruit size, the changes in cell number and cell size during fruit development were analysed. Pineapple cv. ‘Comte de Paris’ fruit were collected every 15 days from 0 to 75 days after the first flower appeared (DAFF), and the flesh of the second (top) and the sixth (base) fruitlets were selected for histological observation. Cell size exhibited a rapid increase up to 60 DAFF, while the cell rapidly proliferated up to 30 DAFF, then slowed down but continued to proliferate. Although grown under identical conditions, ‘Comte de Paris’ pineapples grew to different sizes. The results showed that the cell number, the cell size and the number of fruitlets were correlated with the final fruit size/weight regulation, but that cell number played the most important role.

Cell size, total and protein nitrogen, and preclimacteric respiration have been studied for light and heavy crop fruit of certain Tasmanian-grown apple varieties. Differences in size of fruit from light and heavy crops have been shown to be due mainly to differences in cell size rather than in cell number. Respiration per cell, protein nitrogen per cell, and cell volume were closely intercorrelated but respiration per unit protein is greater in light crop fruit than in heavy crop.

Load Effects

The effects of rootstock on growth of fruit cell number and size of `Gala' apple trees (Malus domestica Borkh) were investigated over three consecutive seasons (2000-02) growing on Malling 26 (M.26), Ottawa-3, Pajam-1, and Vineland (V)-605 rootstocks at the Peninsular Agricultural Research Station near Sturgeon Bay, WI. Fruit growth as a function of cell division and expansion was monitored from full bloom until harvest using scanning electron microscopy (SEM). Cell count and cell size measurements showed that rootstock had no affect on fruit growth and final size even when crop load effects were removed. Cell division ceased about 5 to 6 weeks after full bloom (WAFB) followed by cell expansion. Fruit size was positively correlated (r2 = 0.85) with cell size, suggesting that differences in fruit size were primarily a result of changes in cell size rather than cell number or intercellular space (IS).

Exogenous applications of GA, have induced pathenocarpic fruit set in blueberry; however, size of GA,-treated fruit is smaller than pollinated fruit. The small fruit size in GA3-treated fruit may be related to either cell number and/or cell size. Thus, these parameters were examined throughout development in pollinated, non-pollinated and GA3-treated fruits. Fruit growth followed a double sigmoid pattern. During Stage I (0-25 DAA), fruit size in GA,-treated, pollinated, and non-pollinated fruits averaged 0.33, 0.39, and 0.16 g, respectively. There was little change in fruit size in Stage II (25-45 DAA). At ripening, fruit size averaged 1.7 g for GA,-treated and 2.6 g for pollinated fruits. Non-pollinated fruit abscised in Stage II. At anthesis, mesocarp cell number averaged 9910 cells per median cross sectional area and remained constant up to ripening. In Stage I, cell size in G A3-treated and pollinated fruits increased 7X and 9X respectively. Cell size in both fruit types increased 1.5X and 2.8X during Stage II and Stage 111, respectively. Fruit cell number was set at anthesis and differences in fruit size were due to differences in cell ellongation in Stage I.

Individual F2 tomato plant data in a scatter diagram were used to select segregants for early maturity combined with large fruit size. Selections which were tested in the F3 in replicated and progeny-row tests were carried through to a comparative test in the F5. The relationship of fruit maturity and fruit size in the F2 and F3 indicated that F3 replicated tests using individual plant data are of considerable value in the early selection of superior lines. The F3 performance also provided an indication of the performance of subsequent generations thus permitting immediate decision as to further crossing selfing. The progeny-row test was not sufficiently critical to maintain high selection standards or to provide a reliable indication of the performance of subsequent progenies.
