摘要：采用三因素随机区组设计对不同生态类型黄瓜品种进行不同温度、时间干热处理试验。结果表明:不同黄瓜品种、不同干热处理温度和时间对黄瓜发芽率有极显著差异;干热处理时间与温度有交互作用;干热处理黄瓜种子最安全温度低于75℃,最安全时间短于24 h。

摘要：[Objective]In order to increase anther culture efficiency of pepper.[Method]MS culture media and Bolajiaohong were used in this experiment to study the influences of carbon sources and concentrations on anther callus induction of *** was taken as a material to study influences of plant growth regulators and concentrations on anther callus induction of pepper according to L16（4^5） orthogonal design.[Result]The average callus and embryoid induction rates of maltose at all concentrations were higher than these of sucrose but the difference was not *** maltose or sucrose as a carbon source,3% to 6% concentration was good for increasing induction frequencies of calli and ***,If the concentration was over 6%,the induction rates were declined dramatically with the increase of sugar *** influences of growth regulators on induction rate of calli were listed as 2,4-D﹥ZT﹥NAA﹥KT﹥6-BA;the influences on induction rates of embryoids were listed as 2,4-D﹥NAA﹥ZT﹥KT﹥*** 2,4-D,ZT,NAA and KT had signficant or extremely significant influences on induction rates of calli and embryoids.2,4-D,ZT at 1.0 mg/L and NNA,KT at 0.5 mg/L had the best *** influences of ZT on calli and embryoids were better than those of KT and 6-BA.1.0 mg/L 2,4-D ＋1.0 mg/L ZT ＋0.5 mg/L KT ＋0.5 mg/L 6-BA was the best regulator combination for induction culture of Jiayu anther.[Conclusion]The experiment provided research basis for anther culture of pepper.

摘要：以辣椒红艳为试材,采用均匀设计法考察培养基中不同含量的活性炭、蔗糖和单核苷酸对辣椒花药培养中愈伤组织诱导率和胚状体诱导率的影响。结果表明各因素对辣椒花药愈伤组织诱导率和胚状体诱导率的影响大小均为:蔗糖含量>活性炭含量>单核苷酸含量。诱导愈伤组织的最优条件是1.5 g/L活性炭、65 g/L蔗糖和30 mg/L单核苷酸的组合;诱导胚状体的最优条件为1.5 g/L活性炭,30 g/L蔗糖和30 mg/L单核苷酸的组合。

摘要：一、育苗准备可根据大棚实际情况设计漂浮池的长度,宽度根据各地育苗盘的规格而定。池埂采用红砖、空心砖或土坯做成,宽50厘米为宜。用黑色尼龙塑料薄膜或10～12丝米(1丝米=1×10-4米)的厚膜铺底,膜的边缘要盖在池埂上。最好能在薄膜一侧做个标尺,这样便于以后掌握灌水高度和施肥浓度。苗床做好后,于播种前1周灌水,盖上薄膜以提高水温,并检查是否漏水,如发现渗漏应及时更换薄膜或彻底补好漏洞。
