An experiment was conducted (in 2016–2017 and 2017–2018) to evaluate the post-harvest quality deterioration and to identify cultivars possessing better juice quality during long harvest-to-crush periods. Five promising/commonly cultivated sugarcane cultivars, CoSe 08452, CoS 08276, CoS 08279, CoS 08272 and Co 0238, in sub-tropical regions of India during periods of low and high temperature were selected. Stalks were harvested from November to April and were kept in bundles in different conditions (treatments)—in an open field condition (T1) and sprinkled with water and covered with a thick layer of sugarcane trash (T2). Cane quality parameters (weight loss, sucrose percentage, reducing sugars and dextran) were assessed in both T1 and T2 until 240 h after harvest. Some cultivars appeared to be somewhat more resistant to loss in moisture and sucrose percent during this period, while others seemed to be more susceptible to deterioration and showed the highest loss during April. However, the deterioration was markedly higher in T1 as compared to T2 in all the cultivars. This study suggests that the preparation of post-harvest quality deterioration profiles of promising elite cultivars may be helpful in harvesting schedule to the benefit of growers and millers.

亚热带条件下一些有前景的甘蔗品种收获后的质量概况

进行了一项实验（2016-2017年和2017-2018年），以评估收获后品质变差并确定在长期收获至压榨期间具有更好果汁品质的品种。选择了印度亚热带地区在低温和高温时期五个有前途/常见的甘蔗栽培品种，即CoSe 08452，CoS 08276，CoS 08279，CoS 08272和Co 0238。秸秆从11月至4月收获，并在不同条件（处理）下成束捆装-在露天条件下（T1），撒水并覆盖一层厚厚的甘蔗垃圾（T2）。直到收获后240小时，才在T1和T2中评估甘蔗质量参数（体重减轻，蔗糖百分比，还原糖和葡聚糖）。在此期间，一些栽培品种似乎对水分和蔗糖百分比的损失更有抵抗力，而其他品种似乎更容易退化，并且在四月份表现出最高的损失。但是，与所有品种的T2相比，T1的劣化明显更高。这项研究表明，准备有前途的优良品种的收获后质量恶化状况可能有助于收获时间表，使种植者和种植者受益。
