本文研究了延长天竺葵无根插条低温贮藏寿命的方法。通过在4°C下的聚乙烯袋中高湿度储存和低强度照明（1-30 µEm−2s−1）延迟劣化。储存前应用抗蒸腾剂（例如20或40%的S600）是有害的。将切割的茎在蔗糖溶液中储存24小时前引起一定的脱水，但增加干物质，并在2或5%，这样的预处理有利于储存后生根。预存储叶面应用银硝酸盐（100 ppm）减少根数，但不根重，并防止乙烯损伤的症状，然而，银硫代硫酸盐通过切割茎引起根扭曲，减少根长度和根数。通过结合有益的处理，即使在9周的储存后，也实现了超过50%的生根。
SummaryMethods were investigated for extending the storage life of unrooted cuttings of Pelargonium × hortorum Bailey at low temperatures. Deterioration was delayed by high humidity storage in polyethylene bags at 4°C, and with low intensity illumination (1–30 µEm−2s−1). The pre-storage application of anti-transpirants (e.g. S600 at 20 or 40%) was detrimental. Placing the cut stems in sucrose solutions for 24 h before storage caused some dehydration, but increased dry matter, and at 2 or 5% such pre-treatments were beneficial to post-storage rooting. Pre-storage foliar applications of silver nitrate (100 ppm) reduced root numbers but not root weight and prevented symptoms of ethylene damage; however, silver thiosulphate applied through the cut stem caused root distortion and reduced root length and number. By combining the beneficial treatments, over 50% rooting was achieved even after nine weeks’ storage.
