The freshly harvested mushrooms, subjected to 50-100 KR of 60Co r-irradiation, under the house stemperature (16-21℃) and low temperature (4-10℃) were demonstrated marked effects of fresh preservation. Under the house temperature conditions more than 95% of mushrooms, subjected to r-irradiation, were preservated their fresh state for 6 days, and the veils were not broken.Which is best in the conditions of 100 KR irradiation.The unstreatment mushrooms(control)began break their veils by the third day after the...

The freshly harvested mushrooms, subjected to 50-100 KR of 60Co r-irradiation, under the house stemperature (16-21℃) and low temperature (4-10℃) were demonstrated marked effects of fresh preservation. Under the house temperature conditions more than 95% of mushrooms, subjected to r-irradiation, were preservated their fresh state for 6 days, and the veils were not broken.Which is best in the conditions of 100 KR irradiation.The unstreatment mushrooms(control)began break their veils by the third day after the experiment.Under the low temperature (4-10℃)conditions the duration of fresh preservation prolongated to 20-40 days,the unbroken veils reached 100%. The 50-100 KR r-irradiation can inhibite the activity of mould fungus.The paper boxes full of holes are the best material for the mushrooms which are kept fresh after irradiation.The second best material for package is the cotton yarn bags. The can keep the fresh mushrooms dry, clean and white and keep their good form.But the poly-ethlene plastic bags are the worst for keeping fresh because they make the mushrooms mud and turn to brown and black.There is liquid in the bage.The results from analysis of nutritional elements(Proteri-,Fat,car-bonbydrate,vitamine,water)of irradiated mushrooms shoued that they not losed-their nutritional value.The irradiated mushrooms were tasted by about 60-100 cooks, staffs and workers from 1978-1981.They all considered that the irradiated mushrooms were all in gay colour,fragrant,very dilicious and had no unusual smell,

经5—10万伦~60钴丙种射线辐射的新鲜蘑菇,在室温16—21℃和在低温4—10℃条件下,有明显的保鲜效果。在室条件下,可使蘑菇在6天内保持95%以上不破膜、开伞,以10万伦为最佳。对照组第三天即开始破膜开伞。在低温4—10℃条件下,可使保鲜时间延长至20—40天,100%不开伞,5—10万伦有抑制霉菌生长的作用。 辐射保鲜蘑菇的色装材料,以有孔的纸盒为最好,其次是纱布袋。它们保鲜的蘑菇干爽、洁白、形状好;而聚乙稀/尼龙薄膜效果最差,保鲜的蘑菇为粘稠,色褐黑,袋内有液体。 经过分析辐射保鲜蘑菇的营养成份(旦白质、脂肪、碳水化合物,维生素、水分)没有损失。辐射保鲜的蘑菇从1978—1981年经名厨师和各种工作人员约60—100人的品尝,一致认为,辐射的蘑菇色、香、味皆好,无异味。

Pear ring rot is one of the major diseases of pear tree in Zhejiang province. The fungus grows vigorously on many media, but formation of con-idia occurs only under the light.

A study of some factors affecting the organogenesis of P. sativum L. in in tissue cultures has been carried out. The results show that the B_5 medium is better than the other two base media used for the organogenesis. The medium supplemented with 0.1mg/l of NAA and 0.5-2mg/l of BA obviously promoted the bud differentiation but repressed root formation. When the concentration of sucrose in the medium was increased to 5%, the frequencies of bud induction were much higher than those at 2% of sucrose level....

A study of some factors affecting the organogenesis of P. sativum L. in in tissue cultures has been carried out. The results show that the B_5 medium is better than the other two base media used for the organogenesis. The medium supplemented with 0.1mg/l of NAA and 0.5-2mg/l of BA obviously promoted the bud differentiation but repressed root formation. When the concentration of sucrose in the medium was increased to 5%, the frequencies of bud induction were much higher than those at 2% of sucrose level. The oputimal content of nitrogen in the medium is 840mg/l for the induction of buds, especially when the concentration ratio of NO_3~-to NH_4~+ is at 8:1, frequency can reach 100%. The potentials of organogenesis are various in different explants. In our experements, shoot apices gave the best results and the epicotyls the second-best; the explants of cotyledons produced only a few buds while hypocotyl explants did not produce any buds under the same conditions.

在豌豆(Pisum sativum L.)的组织培养中,研究了影响器官分化频率的几个因素。试验结果表明,基本培养基中B_5较好,补加NAA0.1毫克/升和BA0.5-2毫克/升的B_5培养基明显促进芽的分化,但抑制根的形成;培养基蔗糖浓度从2%提高到5%对芽的诱导有显著促进作用;氮素含量的最适浓度为840毫克/升,特别是NO_3~-与NH_4~+的浓度比为8∶1时,芽的诱导频率可达100%,不同的外植体器官分化能力不同,苗端最好,上胚轴次之,子叶仅产生少数芽,而下胚轴没有分化。
