造林新材料在岱山海岛造林中的应用

通过3种造林新材料在岱山海岛造林中的应用,观测它们对提高造林成活率的影响.结果表明:3种造林新材料对提高夹竹桃Nerium indicum造林成活率基本没有影响,科瀚98对枫香Liquidambar formosana和银杏Ginkgo biloba造林成活率影响较小.植树宝、科瀚98和GGR可显著提高女贞Ligustrum lucidum,重阳木Bischofia javanica,香樟Cinnamomum camphora和木荷Schima superba的造林成活率.图1表1参6     

应用种间杂交方法进行谷子抗除草剂育种的初步研究

野生青狗尾草与中国栽培谷子进行杂交,并用浸有氟特力溶液的小培养皿进行发芽试验,快速鉴别F2代的抗除草剂性能。抗性被隐性基因控制,但更确切的结果有待进一步试验。氟特力不同用药量的选择试验表明,对氟特力抗性与敏感不同的谷子品种在 0~2.4 L/hm2 的处理表现不同,抗型品种的抗性大约是敏感型抗性的5倍。为我们选育谷子抗性新品种提供了依据。

Photosynthate Unloading from Seed Coats of Phaseolus vulgaris L. an Attempt to Define Conditions Required for Stimulation by Abscisic Acid and Benzylamino Purine

The instablity of the stimulation of photosynthate unloading from seed coats of Phaseolus vulgaris by abscisic acid (ABA ) and benzylamino purine ( BAP ) was studied in terms of experimental conditions. ABA stimulated photosynthate unloading at pH 6 and pH 8 without close dependence upon pH. ABA at a concentration range of 10-5-10-4 mol/L displayed stimulatory effect. However, BAP revealed no effect at a concentration range of 10-6-10-4 mol/L. Experiments designed with different transport time of 14C-photosynthate indicated that ABA might act at the plasma membrane of the unloading cells. Reducing endogenous ABA level by diminishing leaf area did not facilitate the manifestation of exogenous ABA function. Potassium ion stimulated photosynthate unloading from seed coats with highest promotion at 100 mmol/L K . However, no dependence of ABA stimulation of photosynthate unloading on K was found.
