摘要:

以‘金艳’猕猴桃果实为材料,通过持续测量田间果实的尺寸,检测田间生长和采后贮藏过程中的果实的品质,研究果实的生长动态规律和贮藏性能。结果表明:‘金艳’猕猴桃果实在谢花后7~175 d的发育过程中,果实尺寸(纵、横径)、单果质量和干物质含量都呈逐渐上升趋势;可溶性固形物含量前期增长缓慢,且波动较大,但在140~175 d期间,迅速上升;果肉颜色h0值在整个果实生长过程中逐渐下降。‘金艳’猕猴桃谢花后175 d左右进入采收期,当可溶性固形物含量在7.5%~8.0%范围时,适宜采收。‘金艳’猕猴桃耐贮性好,在0~1 ℃,相对湿度90%~95%的冷藏条件下,贮藏150 d,硬度下降到10.01 N/cm2。干旱会降低‘金艳’猕猴桃果实的单果质量和干物质含量,影响果实产量和品质。

Abstract:

The growth pattern and storage performance of ‘Jinyan’ kiwi fruits were studied by continuously measuring the
size of developing fruits in the field and the quality of the fruit during growth and postharvest storage. The results showed
that the growth pattern of vertical diameters, transverse diameters, weight and dry matter of fruits revealed a gradually rising
trend during fruit growth from day 7 to 175 after withering. The soluble solids content rose slowly during the early growth
stage, showing significant fluctuations, but rapidly declined during day 140 to 175. The h0 value of pulp color throughout
the entire fruit growth process gradually decreased. ‘Jinyan’ kiwi fruits entered the harvest period 175 days after withering,
when the soluble solids content was 7.5%?8.0%. In addition, the fruis showed good storability and the firmness decreased to
10.01 N/cm2 after storage for 150 days at 0?1 ℃ and RH of 90%?95%. Therefore, our data demonstrate that drought can
reduce the individual fruit weight and dry matter content of ‘Jinyan’ kiwi fruits, thereby impacting fruit yield and quality.
