弯颈或“颈缩”是一种现象，经常看到在削减玫瑰，即花头下垂，由于弯曲的花梗。颈缩被认为是由于木质部的堵塞引起的，无论是由于空气栓塞还是微生物的积累，限制了水吸收到花头，并导致茎弯曲。尽管使用了杀菌剂来减少微生物的生长，但颈缩仍然是切花行业的一个问题，玫瑰继续过早死亡。由于颈缩的发生在品种内和品种间差异很大，已进行了切割月季品种'H30'的转录组分析，以探讨潜在的分子机制。颈缩三个阶段的花序梗样本（直，
Bent-neck or 'necking' is a phenomenon often seen in cut roses, whereby the flower head droops due to a bending of the peduncle. Necking is thought to be caused by a blockage of the xylem, either due to an air embolism or an accumulation of microbes, limiting water uptake to the flower head and causing the stem to bend. Despite the use of biocides to reduce microbial growth, necking remains an issue for the cut flower sector and roses continue to die prematurely. As the occurrence of necking varies widely within and between cultivars, a transcriptome analysis of cut Rosa hybrida cultivar 'H30' has been carried out to investigate the potential molecular mechanisms involved. Peduncle samples of three stages of necking (straight,
