摘要

通过比较对照T1(茎在水中)与蔗糖(T2 ~ T6、(20、40、60、80、100 gL -1)和蔗糖(40 gL -1)与200 mg -1 8-HQC相关的6种脉冲处理(T7)对6个基因型向日葵收获后寿命的影响。脉冲处理24h后，将花序置于含有20 gL -1蔗糖的维持液中，每天按评分标准进行评估，以量化花瓶天数的寿命。在测试的基因型中，脉冲治疗以各种方式促进了寿命。最佳处理为:T5和T6(基因型153);T3和T7(基因型101);T6(基因型181);T7(基因型127);T4和T5(基因型140)和T4(基因型114)。与对照组相比，这些治疗组的寿命增加了两到三天。

Genotype interaction x Helianthus post-harvest longevity.

The post-harvest longevity of six sunflower genotypes developed by Embrapa Soybean was assessed by comparing the control T1 (stems in water) with six pulsing treatments with sucrose, T2 to T6, (20, 40, 60, 80, 100 gL -1 ) and T7, sucrose (40 gL -1 ) associated with 200 mgL -1 8-HQC. After pulsing treatment for 24h, the inflorescences were placed in a maintenance solution with 20 gL -1 sucrose and assessed daily by score criteria, defined to quantify the longevity in number of vase days. The pulsing treatments promoted longevity in various ways among the genotypes tested. The best treatments were: T5 and T6 (genotype 153); T3 and T7 (genotype 101); T6 (genotype 181); T7 (genotype 127); T4 and T5 (genotype 140) and T4 (genotype 114). Longevity was increased by two to three days in these treatments compared to the control.

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
