【摘要】 植物资源菥在川西北草原分布广泛,储量比较丰富。为研究和利用这一资源,进行了一些试验,得到了下列结果:(1)将川西北草原几个地区所采集的菥种子进行油分分析,分析结果表明,菥种子油分的主要脂肪酸组成和普通甘蓝型油菜相近,其种子油可供食用和工业用。由于菥是甘蓝型油菜的较近缘物种,其种子油的亚油酸和亚麻酸含量比普通甘蓝型油菜的高,认为有可能作为甘蓝型油菜优质育种的杂交亲本。(2)菥种子引种成都种植时,基本上能正常生长发育,其生育期为190~197d,单株种子产量为3.9~5.6g,理论种子产量为585~840kg/hm2。虽然菥在成都的种子产量较低,但它在川西北草原龙日坝种植时,其种子产量达2250kg/hm2。这说明菥在川西北草原人工种植时有一定的增产潜力。(3)菥在成都种植的产苔量为15675~16800kg/hm2,在成都地区作为绿色野菜有一定的潜力。更多还原

【Abstract】 Thlaspi arvense is abundant and widely distributed in the grassland of West Sichuan. In or- der to exploit this plant resource,the following experiments were carried out and the results are as fol- lows. 1. The data of the seed oil analysis of Th.arvense,When cultivated in Chengdu,gave a plant seed yield of 3.9~5.6 g and a theoreticad yield of 588~840 kg/hm2,while it gave a seed yeld of 2250 kg/hm2, when cultivated in the grassland.It is suggested that Th.arvense is possible to be cultivated in the grassland of West Sichuan. 3. The picking of young budding branches of Th.arvense,when cultivated in Chengdu, gave a harvest of 15675~16800 kg/hm2. It is suggested that Th.arvense may be cultivated in Chengdu for vegetable uses.更多还原
