Abstract

Kamchatka berries contain many valuable organic and mineral compounds. However, the ripe berries are not very firm and have low transport resistance. We aimed to study the effect of chitosan solutions of different molecular weights on the growth, yield, and quality of Kamchatka berries. Chitosan with lower molecular weights, 3 and 12 kDa, stimulated plant growth, while those with molecular weights above 50 kDa reduced plant growth compared with control shrubs. Chitosan 125 and 500 kDa increased Kamchatka berry yield. In addition, chitosan 125 kDa increased fruit weight throughout the yield period. Fruit sprayed with chitosan 3, 5, and 50 kDa were dark in colour at harvest. Chitosan 3, 5, 12, and 50 kDa increased fruit/skin resistance to mechanical damage. Finally, chitosan 3, 5, 50, and 950 kDa increased average fruit firmness. Overall, we recommend higher molecular weight chitosan to increase yield and lower molecular weight chitosan to increase firmness and resistance to damage.

施用不同分子量壳聚糖对堪察加浆果生长和品质的影响:第1部分

堪察加浆果含有许多有价值的有机和矿物质化合物。然而，成熟的浆果不是很结实，抗运输能力低。研究不同分子量壳聚糖溶液对堪察加浆果生长、产量和品质的影响。分子量为3和12 kDa的低分子量壳聚糖对植株生长有促进作用，而分子量为50 kDa以上的壳聚糖对植株生长有抑制作用。125和500 kDa壳聚糖可提高堪察加莓产量。此外，125 kDa的壳聚糖在整个产期都增加了果实重。3、5和50 kDa壳聚糖喷施的果实在收获时颜色较深。3、5、12和50 kDa的壳聚糖增加了水果/果皮对机械损伤的抵抗力。最后，3、5、50和950 kDa的壳聚糖增加了水果的平均硬度。总的来说，我们推荐高分子量的壳聚糖来提高收率，低分子量的壳聚糖来增加硬度和抗损伤性。
