繁殖体

This study focused on characteristics related to the reproductive biology of Cyathea podophylla Copel. gametophytes, including growth habits, sexual expression, antheridiogen, ploidy, and genetic load.

本文著重於与鬼桫椤配子体繁殖有关之各种特性的研究，如生长习性，配子器发生顺序，促精素，倍体性，及遗传负荷等。

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.

以邓恩桉种子为外植体，探讨用最少种子快速繁殖最多幼苗的方法，结果表明：MS培养基是较适合邓恩桉种子萌芽和生长的基本培养基；诱导种子直接脱分化成愈伤组织的较佳培养基配方为MS+KT1.0 mg/L+2，4-D2.0 mg/L+半胱氨酸30 mg/L；以邓恩桉实生苗的芽来繁芽的较理想培养基配方为H+BA2.0 mg/L+IAA0.2 mg/L；邓恩桉实生苗的根诱导愈伤组织的较佳培养基配方为MS+6-BA2.0 mg/L+NAA0.2 mg/L；诱导邓恩桉下胚轴分化芽较佳培养基配方为B5+6-BA2.0 mg/L+2，4-D0.2 mg/L；诱导邓恩桉下胚轴脱分化为胚性愈伤组织的较佳培养基配方为B5+Ad2.0 mg/L+IAA0.2 mg/L。

Objective To study rapid propagation and in vitro flowering system for Dendrobium denndanum.

目的研究叠鞘石斛的快速繁殖及离体开花的培养体系。

To examine the effect of photoperiods on sexual reproduction of sea weed Hizikia fusiformis Okamura, receptacles were collected and incubated in three different light periods.

对羊栖菜的生殖托在不同光照周期条件下进行离体培养，观察卵细胞的释放与受精情况，以及受精卵的发育情况，以探讨光照周期对其有性繁殖过程的影响。

The recurrence of warm conditions has allowed some detailed interpretation of the effect on the "hyperthermal" B.sarsi,resulting in an overwinter reduction of breeding adults,attributable either to reduced survival to maturity or to emigration away from the area during warmer winters.

温暖条件的循环导致B·sarsi种群能够越冬进行繁殖的成体数量减少。实际上数量减少的主要原因是由于可存活过冬的个体减少、或者暖冬导致个体迁徙到别处。

Objective: To establish a protocol of rapid clonal propagation of Saussurea involucrate by using embryo as explants.

We are doing a project on Kori Bustards in Botswana and would like to tax your memory of these birds breeding in Jwana Park.

我们正在做的一个项目， kori bustards在博茨瓦纳和想税，您的记忆体，这些鸟类繁殖在jwana公园。

Methods Collected the eggs of Lucilia sericata, artificial rear the maggot under the experimental condition, Observed the time orderliness of maggot living.

方法搜集丝光绿蝇虫卵，在实验室无菌条件下进行人工饲养与繁殖，观察蛆虫生长时间与规律，对虫卵和虫体采用双重消毒处理，对蛆虫进行细菌学和病毒学检测。

This condition may be ralated to the source tissue which had lost morphogenic potential.

原生质体的愈伤组织在继代中生长旺盛，繁殖迅速，但无形态发生，这可能与起始材料本身已丧失分化能力有关。
