Abstract
Abstract An educational kit for the classroom study of plants including a compact plant growth environment and a seed of fast-cycling Brassica plants. The fast-cycling plants grow in compact areas and have generation cycle times of sixty days or less making them convenient for classroom study. Various experiments on plant growth, physiology and genetics can be performed with the kits.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
86 words
An educational kit for the classroom study of fast-cycling Brassica plants comprising a compact plant growth environment for plants suitable for classroom use, including physical containers for plants, and a watering system to continually water plants in the containers with minimum maintenance; and a stock of seeds of fast=cycling Brassica plants having an average growing cycle of not more than about sixty days and of a size appropriate for the compact growth environment, the seeds selected to yield plants having easily observable traits of educational interest.
Claim 2
Dependent Claim
86 words
An educational kit for the classroom study of fast-cycling Brassica plants comprising a compact plant growth environment for plants suitable for classroom use, including physical containers for plants, and a watering system to continually water plants in the containers with minimum maintenance; and a stock of seeds of fast=cycling Brassica plants having an average growing cycle of not more than about sixty days and of a size appropriate for the compact growth environment, the seeds selected to yield plants having easily observable traits of educational interest.
Claim 3
Dependent Claim
57 words
An educational kit as claimed in claim 1 further comprising a quantity of a plant growth factor and wherein the trait selected for in the plants is high sensitivity to the plant growth factor so that easily observed differences will develop between groups of plants exposed to the growth factor and groups of similar plants not exposed.
Claim 4
Dependent Claim
31 words
An educational kit as claimed in claim 2 wherein the growth factor is a negative growth factor selected from the group consisting of antibiotics, herbicides, parasites, pathogens, pests and competitive plants.
Claim 5
Dependent Claim
28 words
An educational kit as claimed in claim 2 wherein the growth factor is a positive growth factor selected from the group consisting of plant nutrients, hormones and symbiots.
Claim 6
Dependent Claim
23 words
An educational kit as claimed in claim 1 further including hand pollination devices so that hand pollinations can be accomplished between selected plants.
Claim 7
Dependent Claim
28 words
An educational kit as claimed in claim 1 wherein the physical containers for the plants are small plant minipots having a hollow interior and a porous bottom pad.
Claim 8
Dependent Claim
38 words
An educational kit as claimed in claim 6 wherein the watering system includes a porous wicking pad onto which the minipots are placed and at least one water reservoir into which one end of the wicking pad extends.
Claim 9
Dependent Claim
20 words
An educational kit as claimed in claim 6 wherein an optimized soil mixture is provided in each of the minipots.
Claim 10
Dependent Claim
44 words
An educational kit as claimed in claim 1 wherein the Brassica seeds are selected from the group consisting of Brassica campestris (CrGC 1), Brassica nigra (CrGC 2), Brassica oleracea (CrGc 3), Brassica juncea (CrGC 4), Brassica napus (CrGC 5), and Brassica carinata (CrGC 6).
Claim 11
Dependent Claim
31 words
An educational kit according to claim 6 wherein the minipots are placed adjacent one another and are separated by vertical separators extending upward between the minipots, whereby the separators simulate trellises.
Claim 12
Dependent Claim
21 words
An educational kit according to claim 10 wherein the separator includes notches for holding string onto which the plants may climb.
Claim 13
Dependent Claim
103 words
An educational kit for the classroom study of plant genetics in fast-cycling Brassica plants comprising a compact plant growth environment including a physical plant containment, and a watering system; pollination tools for hand-pollination of plants; and at least two stocks of seeds of fast-cycling Brassica plants characterized by a characteristic average growing cycle under optimal conditions of not more than about sixty days, each of the two stocks having one of an allelic pair of chromosomes conditioning an easily observable phenotypic trait so that crosses of the two stocks and their progeny can be readily made and the phenotypes of the progeny observed.
Claim 14
Dependent Claim
103 words
An educational kit for the classroom study of plant genetics in fast-cycling Brassica plants comprising a compact plant growth environment including a physical plant containment, and a watering system; pollination tools for hand-pollination of plants; and at least two stocks of seeds of fast-cycling Brassica plants characterized by a characteristic average growing cycle under optimal conditions of not more than about sixty days, each of the two stocks having one of an allelic pair of chromosomes conditioning an easily observable phenotypic trait so that crosses of the two stocks and their progeny can be readily made and the phenotypes of the progeny observed.
Claim 15
Dependent Claim
21 words
An educational kit as claimed in claim 12 wherein the pollination tools include a bee thorax adhered to a small stick.
Claim 16
Dependent Claim
22 words
An educational kit as claimed in claim 12 wherein the watering system continually waters plants in the plant containment with minimal supervision.
Claim 17
Dependent Claim
26 words
An educational kit as claimed in claim 14 wherein the plant containment includes individual small plant minipots having a hollow interior and a porous bottom pad.
Claim 18
Dependent Claim
45 words
An educational kit as claimed in claim 15 wherein the watering system includes a porous wicking pad extending under the plant minipots and at least one water reservoir into which the wicking pad extends so that water is delivered to the minipots by capillary action.
Claim 19
Independent Claim
118 words
A method of studying plant growth and plant genetics utilizing fast-cycling Brassica seeds, comprising: sowing the seeds of fast-cycling Brassica plants in a compact plant growth environment for Brassica plants suitable for classroom use, including physical containers for the plants and a watering system for continually watering the plants in the containers with minimum maintenance; and providing sufficient light to allowing rapid growth of the plants; wherein the seeds of the fast-cycling Brassica plants have been bred to develop into plants having a characteristic average growing cycle of not more than sixty days and having a size appropriate for the compact plant growth environment, the seeds being selected to yield plants having easily observable traits of educational interest.
Claim 20
Independent Claim
