Abstract

A field experiment according to simple randomized block design was conducted with the aim to find out the effects of foliar spray of thiamine hydrochloride (vitamin B1) on growth, nutrient uptake and yield characteristics of mustard (Brassica juncea L.) variety (Var.) Varuna. The plants were sprayed with 0.01, 0.02 and 0.03 wt% thiamine hydrochloride solution and a spray of distilled water was also maintained as a control. Spraying was done in a single spray after 40 days of sowing (DAS) i.e., at flower initiation stage (Ansari, 1988). The growth parameters studied include plant fresh weight, plant dry weight, leaf area (LA), leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and uptake of N and P at different growth stages. Yield as well as its components such as number of pods per plant, 1000 seed weight, yield, biological yield, harvest index, oil content and oil yield were measured at harvest. In general spray of 0.03 wt% of thiamine hydrochloride solution was found to be the best in comparison to any other concentration of the treatment for most of the parameters studied. Growth parameters like plant fresh weight, plant dry weight, CGR, RGR and NAR showed significant results at the early stages of sampling (that is, 60–80 DAS). In case of LA and LAI, there was no significant difference between thiamine hydrochloride spray treatments. Thiamine hydrochloride solution at 0.03 wt% was found significantly best in case of nitrogen uptake at 60 and 80 DAS while in case of phosphorous uptake, 0.02% was statistically the best; however, it was at par with 0.03 wt% thiamine hydrochloride solution at 80 DAS. Different yield parameters like the pod number per plant, biological yield and seed yield as well as oil yield registered significant results. The results suggest that the performance of B. juncea L. var. Varuna can be improved by spraying the plants with aqueous thiamine hydrochloride solution. Thus, it was concluded that the spray of thiamine hydrochloride solution ensured better growth and yield.
维生素B1(盐酸硫胺素)对芥菜生长和产量的促进作用
采用简单随机区组设计,研究了叶面喷施盐酸硫胺素(维生素B1)对芥菜(Brassica juncea L.) Varuna生长、养分吸收及产量特性的影响。分别用0.01、0.02和0.03 wt%盐酸硫胺素溶液喷淋植株,并保持蒸馏水喷雾作为对照。在播种40天后(DAS),即在开花阶段进行单次喷洒(Ansari, 1988)。研究的生长参数包括植株鲜重、干重、叶面积(LA)、叶面积指数(LAI)、作物生长率(CGR)、相对生长率(RGR)、净同化率(NAR)和不同生育期的氮磷吸收量。采收时测定单株荚果数、千粒重、产量、生物产量、收获指数、含油量和出油量等产量及其组成部分。总的来说,与任何其他浓度的处理相比,0.03 wt%盐酸硫胺素溶液的喷雾处理对大多数参数的研究都是最好的。植株鲜重、干重、CGR、RGR和NAR等生长参数在取样初期(即60-80 DAS)均有显著结果。在LA和LAI的情况下,盐酸硫胺素喷雾处理之间无显著差异。在60和80 DAS的氮吸收情况下,0.03 wt%的盐酸硫胺素溶液效果最好,而在磷吸收情况下,0.02%的硫胺素溶液效果最好;然而,在80 DAS时,与0.03 wt%盐酸硫胺素溶液相当。单株荚果数、生物产量、种子产量、油料产量等不同产量参数均有显著差异。结果表明,喷施盐酸硫胺素水溶液可提高芥菜的抑菌性能。由此可见,喷施盐酸硫胺素溶液能保证较好的生长和产量。
