摘要
用100、200、400、600和800 mg/L(各含2%尿素)乙烯利对湛江地区的珍珠菠萝进行综合催花效应研究,结果表明:用乙烯利在夏季进行催花的最佳浓度为200 mg/L,随着浓度的增加,菠萝果实越小,各处理在单果重、果实纵径、植株重量、最长叶宽等指标上存在极显著差异,但对抽蕾时间、果实可溶性固形物和可滴定酸含量的影响差异不显著。
Integrated effects （including flowering rate, plant growth and fruit weight etc） on Zhenzhu pineapple＇s floral induction were studied using different ethrel solution（100,200,400,600,800 mg/L）with 2% urea. Results showed that 200 mg/L ethrel with 2% urea was the best appropriate treatment to induce the pineaple＇s flowering in Summer. With the enhancement of ethrel application, the fruit weight ,the fruit length ,the plant weight, the width of the longest leaf would drop dramatically. However, it made little difference in the content of total soluble solids and titratable acid.
