研究 7种梨果实袋的光、温特性 ,结果表明 :单层袋透光率明显高于双层袋 ;梨果实袋内温度高于树冠内温度 ,昼夜变化趋势与冠温相同 ;单层木浆纸袋内平均温度较低 ,双层纸袋和涂蜡纸袋内温度较高 ,套袋期间套袋果平均温度高于无袋果 ,平均高 0 .13~ 0 .4 4℃ ,最高达 0 .4 4~ 1.10℃ ;套袋期 ,套袋梨果呼吸强度均高于无袋果。鸭梨套袋可明显改善果实外观品质 ,但果实含糖量有降低的趋势。 The results showed that the light transmittance of single pouch was significantly higher than that of double pouch; the temperature inside the bag of pear fruit was higher than that of canopy, and the diurnal variation trend was the same as that of canopy temperature; The average temperature in the pulp-paper bag is lower, the temperature in the double paper bag and the wax-coated paper bag is higher, and the average temperature of bagging fruit during bagging is higher than that of the bagless fruit, with an average height of 0.13 ~ 0.44 ℃ and a maximum of 0. 4 4 ~ 1.10 ℃; Bagging period, bagged pear fruit respiration intensity were higher than bagless fruit. Bagged pear can significantly improve the appearance of fruit quality, but the fruit sugar content has decreased.

环状核糖核酸(circular RNA,circRNA)是一类新型非编码RNA分子,通常表现为共价闭合的环状分子,同时缺少5′帽和3′尾。它在真核生物中大量存在,成为近年来RNA领域的研究热点。环状RNA具有多种功能,例如丰富的表达,细胞或组织特异性表达,以及对RNA酶引起的更高降解抵抗力。它与组织发育和疾病发生发展密切相关,在多种疾病的发病和发展中发挥重要作用,并且可作为新型疾病分子标志物。因此
