随着植物生长物质添加含量的增加，Ⅱ型发状根的愈伤组织化程度也加大，同时也抑制了从发状根或其形成的愈伤组织上形成新的分枝侧根。

When auxin level was increased, callusing frequencies of Type Ⅰ,Ⅱ hairy roots were also increased, while formation of lateral root from hairy root or callus was inhibited.

随着生长激素添加浓度的增加，Ⅰ、Ⅱ型发状根的愈伤组织化程度也加大，同时也抑制了从发状根或其形成的愈伤组织上形成新的分枝侧根。

The declining of the value of IAA/ZR was beneficial to callusing, the other way around was beneficial to rooting. The higher value of IAA/ABA was better for root-promoting during the shape of rooting anlage and the emergence of root.

IAA/ZR比值的下降有利于愈伤组织的形成，上升有利于不定根的形成；在根原基形成和不定根出现期，高的IAA/ABA对生根有利。

This paper reviewed microsclerotia or spores in soil are stimulated to germinate by host root exudates, hyphae colonizes on the surface of root, pathogens penetrate epidermis and develop in cortex, expand on stem and leaf, and symptom development, shows that host plant develops various barriers to restrain this fungus invasion.

本文系统探讨了土壤中微菌核或孢子受寄主根系分泌物的刺激，开始萌发、产生的菌丝在寄主根表面定殖、穿过表皮、在皮层中发生及在寄主体内扩展和症状形成等黄萎病菌侵染棉花的过程，阐述了寄主植物形成多级防御反应阻击病原菌的入侵。

With the increasing of NO3- concentration, the biomass, root absorbability and root absorbing area declined under NaNO3 treatment. The biomass was gradually increased with NO3- concentration increasing under Ca(NO3)2 and KNO3 treatments, while NO3- concentration excessed 98 mmol·L-1, the fresh weight of cucumber seedlings was gradually decreased.

NaNO3处理条件下，随着NO3-浓度增加，黄瓜幼苗生物量降低、根系吸收能力及吸收面积下降；而低浓度Ca(NO3)2及KNO3处理下，黄瓜幼苗生物量随着NO3-浓度增加而增加，当大于98 mmol·L-1时，黄瓜幼苗鲜重逐渐降低。

In details, the strongest inhabitation to the shoot growth was observed when neutral soluble fractionates were supplied. The shoot biomass with neutral soluble fractionates added was decreased by 10.52% over the blank control, resulting in obvious increase of root: shoot ratio. It suggests that the root exudates would be self-poisonous. Besides, both acid and alkaline soluble fractionates exhibited the trend to increase the stem height and it is necessary to exploit the reasons.

在培养液中，分别加入分组的烤烟根系分泌物，均显著降低根系对NO_3~-、H_2PO_4~-、K~+离子的吸收和根系活力，推测根系分泌物中产生抑制作用的物质可作用在相当宽的pH范围；其中，碱溶性组分对H_2PO_4~-、酸溶性组分对K~+、中性组分对NO_3的吸收和根系活力的抑制作用较强，推测在烤烟根系分泌物中，可能存在多种抑制烤烟生K和养分吸收的化学物质；另外，抑制作用随着根系分泌物浓度的增加而增强。
