This paper aims to find out the nutrition characteristics and fertilizer absorption rule of Castor in arid red soil districts under the subtropical climate of Yunnan province, and establish a corresponding fertilizing technology under the condition. It choose the variety TCO-202 of Castor (Ricinus communis L.) as test material to observe and record the dry matter accumulation of each organ as root, stem, foliage and inflorescence, which are in the five critical growth stages as seedling stage、 bud stage、 blooming stage、 filling stage、 maturation stage of Castor {Ricinus communis L. respectively, and measure out the fertilizer absorption amount of nitrogen, phosphorus and potassium.

That, however, is what has happened: from the trunk of that tree of vengefulness and hatred, Jewish hatred—the profoundest and sublimest kind of hatred, capable of creating ideals and reversing values, the like of which has never existed on earth before—there grew something equally incomparable, a new love, the profoundest and sublimest kind of love—and from what other trunk could it have grown?
可这是个大事:从那报复的树干中,从那犹太的仇恨中,从那地球上从未有过的最深刻、最极端的、能创造理想、转变价值的仇恨中生长出某种同样无与伦比的东西,一种新的爱,各种爱中最深刻最极端的一种:——从其它哪根树干中能够长出这种爱?

This paper presents a study of Eucalyptus dunnii tissue culture, using its seeds as explants. The results reveal that MS medium is a suitable basic medium for its seeds to germinate and grow; that MS+KT1.0 mg/L+2, 4-D2.0 mg/L+Homocysteine30mg/L is a good medium to induce its seeds to dedifferentiate directly into callus; that H+6-BA2.0 mg/L+IAA0.2 mg/L is a good medium to make its bud on the seedling reproduce more buds; that MS+6-BA2.0 mg/L+NAA0.2 mg/L is a better medium to induce its root on the seedling into callus; that B5+6-BA2.0 mg/L+2, 4-D0.2 mg/L can induce its under-hypocotyl to differentiate into buds; and that B5+Ad2.0 mg/L+IAA0.2 mg/L can induce its under-hypocotyl into callus to generate normal buds.

Agrobacterium tumefaciens-mediated transformation system of Medicago truncatula cotyledonary-node explants Abstract The three-day-old seedlings of Medicago truncatula, which geminated in medium containing up to 5mg/L 6-BA, were used to prepare the cotyledonary-node explants which contained one cotyledon and 1-2mm of split hypocotyl. High-efficiency regeneration system of Medicago truncarula was developed by axillary shoot organogenesis of cotyledonary-node explants.

The induced rate of rooting with naphthaleneacetic acid was higher than indolebutyric acid. The medium supplemented with 50 mg/l ascorbic acid and 0.5 mg/l NAA could improve the growth and development of root system. 57.5% of shoots could develop to the well-rooted plantlets and develop into healthy and fertile plants when planted in soil.
将芽体分割进行发根试验的结果显示,naphthaleneacetic acid诱导根系的效果优於indolebutyric acid,添加50 mg/l抗坏血酸和0.5 mg/l NAA之培养基则有更好的效果,约有57.5%的芽体可再生成具有旺盛根系的植株,经移植至土壤中也可生长健旺及正常开花。
