摘要
花生芽苗菜是高端芽苗菜种类之一,为筛选适合芽苗菜生产的花生新品系和优化其配套培养方法,分别以水培法、沙培法、生长素法为处理进行花生芽苗菜的培养,测定分析了3种培养方法处理5个花生新品系的芽苗菜产量及其胚轴长度、胚轴粗度和胚根长度等技术指标。结果表明:沙培法处理、生长素处理的增重系数分别达4.21(±0.49)和4.20(±0.48),显著优于水培法3.52(±0.33)处理。水培法处理PN01增重系数最大,达4.44,PN05次之,为4.02;沙培法处理和生长素处理PN05增重系数均最大,分别达5.27和5.50,PN01次之,均为5.14。生长素处理的花生芽苗菜胚轴长度、胚轴粗度和胚根长度分别为4.41(±0.28)、6.74(±0.13)、1.60(±0.11)cm,与水培法处理差异极显著,其中对胚根长度和粗度起显著促进作用、对胚根长度起显著抑制作用;沙培法处理分别为4.83(±0.28)、6.00(±0.20)、5.51(±0.43)cm,与水培法处理比较,胚轴长度、胚根长度差异极显著,胚根粗度差异不显著。可见,生长素调控可通过促进胚轴长度、粗度的增长和抑制胚根长度的伸长,提高花生芽苗菜产量和质量;沙培法可促进胚轴长度的伸长、提高花生芽苗菜产量,但是也促进胚根长度的伸长、降低了花生芽苗菜的商品性。PN01和PN05是生产花生芽苗菜的优异品系,其中PN05尤其适宜于沙培法和生长素调控法,而PN01更适宜于水培法。
Peanut sprout is a kind of high-quality sprout. In order to screen suitable peanut lines and treatment methods for peanut sprout production,water culture method,sand culture method and auxin treatment method were used to treat five peanut lines. The fresh weight,hypocotyl length,hypocotyl thickness and radicle length were measured. The results showed that the weight gain coefficient of sand culture treatment and auxin treatment were 4.21±（0.49） and 4.20（±0.48）,which were significantly higer than water culture treatment 3.52（±0.33）. Under the water culture treatment,the weight gain coefficient of PN01 was the highest（4.44）,followed by PN05（4.02）.But under sand culture and auxin treatment,the weight gain coefficient of PN05 line was the highest,respectively 5.27and 5.50. PN01 was both followed secondly by 5.14. The hypocotyl length,hypocotyl thickness and radicle length of auxin-treated peanut sprouts are 4.41（ ±0.28）cm,6.74（ ±0.13）mm and 1.60（ ±0.11）cm. Comparing with water culture treatment,the differences were extremely significant. Auxin treatment can promote the radicle length and thickness significantly and inhibit the endoderm growth. The hypocotyl length,hypocotyl thickness and radicle length of peanut sprouts in sand culture method were 4.83（±0.28）cm、6.00（±0.20）mm and 5.51（±0.43）cm. The hypocotyl length and radicle length were signficiantly better than water culture method,but the hypocotyl thickness was not dramatically. It can be seen that auxin regulation can increase the yield and quality of peanut sprouts by promoting the growth of the length and thickness of the hypocotyl but concurrently inhibiting the elongation of the radicle length. The sand culture method can promote the elongation of the hypocotyl length and increase the peanut sprouts yield but also can promote the elongation of radicle length and reduce the commerciality of peanut sprouts. PN01 and PN05 are suitable lines for the production of peanut sprouts. PN05 is especially suitable for the sand culture and auxin treatment method,while PN01 line is more suitable for water culture method.
