据了解，海南椰子产业正面临“内忧外患”的困境，一方面东南亚国家椰子加工业的发展，不仅抬高了椰子收购价，而且减少了椰子出口，加剧了海南椰子供应紧张的局面。另一方面，海南省内的椰子种植基本看天收果，岛内很多椰子树品种老化严重，缺少管理，导致近年来椰子产量大幅减少。 相似文献

椰子是热带地区主要木本油料作物,也是食品能源作物;不仅口感清凉,风味独特,并含有大量的营养成分,并且具有解毒、美容、消毒等功效。随着椰子产业发展,对椰子需求越来越大,因此,椰子规模化生产发展迅速,关于椰子各方面研究非常重要,同时也受到人们重视。然而,与其他经济作物相比,椰子种质资源、栽培、产品加工及作用等研究较晚,研究基础较为薄弱,但是,近20 a来,国内外在椰子种质资源、栽培、生理生化、分子生物学、产品加工等及作用研究取得一些重要进展,为椰子生产和发展提供理论基础和技术支撑。本文综合分析了椰子种植资源收集、鉴定评价、创新利用、耕作栽培、栽培生理等研究进展情况,并介绍了椰子产品加工利用的研究进展,就进一步的研究和利用提出具体建议,以期为今后椰子产业发展提供参考。 相似文献

以CO39四叶期水稻苗的叶片为材料,提取水稻基因组DNA,通过PCR扩增获得水稻几丁质酶基因OsRCchil,经序列测定得知该基因大小为1 065 bp,序列比对结果显示,OsRCchil与已知的水稻几丁质酶基因Oryza sativa(japonica cultivar-group)class Ⅲ chitinase RCB4 (Rcb4) mRNA (AF350426)、Oryza sativa chitinasemRNA (AF330230) 及 Oryza sativa subsp.japonica class Ⅲ chitinase(chibl)gene(AF296279)的相似性分别为85.9%、76.2%和75.0%.因此,可以认为OsRCchil基因是class Ⅲ几丁质酶基因家族的一个成员. 相似文献

Coconut fibres were subjected to chemical treatment to obtain softer and finer fibres, suitable to blend with other finer fibre like jute. The chemical softening recipe was optimized using Box-Behnken design of experiments as 40 % Na2S, 10 % NaOH and 6 % Na2CO3, which notably reduced the fineness (33 %) and flexural rigidity (74 %) and improved tensile property of coconut fibre. Effect of softening of coconut fibre on its process performance was studied in high speed mechanized spinning system at different blend ratios with jute. Blending with jute assists in spinning of coconut fibre to produce yarn of 520 tex at production rate of 5-6 kg/h, as compared to 15 kg/day for hand spun 5300 tex raw coconut fibre yarn in manual system. Analysis of blended yarn structure in terms of packing density, radial distribution of fiber components (SEM) and mass irregularity were investigated. SEM shows yarns made from softened coconut fibre -jute blends are more compact than raw coconut fibre -jute blend yarns. Coconut fibres were preferentially migrated to core of the yarn. Major yarn properties viz., tensile strength, and flexural rigidity of raw and chemically softened blended yarns were compared against their finest possible 100 % coconut fibre yarn properties. Yarn made up to 50:50 chemically softened coconut fibre-jute blend showed much better spinning performance, and having superior property in terms of reduced diameter, higher compactness, strength, initial modulus and less flexural rigidity than 100 % raw, 100 % chemically softened coconut fibre rope, and raw coconut fibre-jute blend yarns. 相似文献
